## Abstract

An analysis trigger monitoring system is provided in one or more virtual assets. One or more analysis trigger parameters, including security threat patterns, are defined and analysis trigger data is generated. The one or more analysis trigger monitoring systems are used to monitor at least a portion of the message traffic sent to, or sent from, the one or more virtual assets to detect any message including one or more of the one or more analysis trigger parameters. Any detected message is identified as a potential security threat and is assigned a threat score, which is provided to the virtual asset. A copy of at least a portion of any detected message including one or more of the one or more analysis trigger parameters is then transferred to one or more analysis systems for further analysis using a second communication channel.

No. 14/171,438 (INTU148121), filed on Feb. 3, 2014, entitled “METHOD AND SYSTEM FOR VIRTUAL ASSET ASSISTED EXTRUSION AND INTRUSION DETECTION IN A CLOUD COMPUTING ENVIRONMENT,” which is herein incorporated by reference in its entirety as if it were fully set forth herein. This application is also a continuation of Lietz, et al., U.S. patent application Ser. No. 14/292,700 (INTU148245), filed on May 30, 2014, entitled METHOD AND APPARATUS FOR A SCORING SERVICE FOR SECURITY THREAT MANAGEMENT, ” which is herein incorporated by reference in its entirety as if it were fully set forth herein.


BACKGROUND
As various forms of distributed computing, such as cloud computing, have come to dominate the computing landscape, security has become a bottleneck issue that currently prevents the complete migration of various capabilities and systems associated with sensitive data, such as financial data, to cloud-based infrastructures, and/or other distributive computing models. This is because many owners and operators of data centers that provide access to data and other resources are extremely hesitant to allow their data and resources to be accessed, processed, and/or otherwise used, by virtual assets, such as virtual machine and server instances, in the cloud.
In a cloud computing environment, various virtual assets, such as, but not limited to, virtual machine instances, data stores, and various services, are created, launched, or instantiated, in the cloud for use by an “owner” of the virtual asset, herein also referred to as a user of the virtual asset.
Herein the terms “owner” and “user” of a virtual asset include, but are not limited to, applications, systems, and sub-systems of software and/or hardware, as well as persons or entities associated with an account number, or other identity, through which the virtual asset is purchased, approved, managed, used, and/or created.
Typically a given cloud computing environment receives message traffic through one or more network communications channels. One long standing problem associated with cloud computing environments is the fact that malware can be introduced into the cloud computing environment, just as in any computing environment, via these network communications channels. The introduction of malware into a virtual asset, and therefore into an application, service, enterprise, or cloud infrastructure of a cloud computing environment is known as intrusion. However, once introduced, some forms of malware take control of some, or all, of the infected virtual asset functionality and use the virtual asset to send outbound messages and data. This outbound malware mechanism is referred to as extrusion.
The detection of both malware intrusion and extrusion is an important part of making cloud computing environments more secure. However, a given cloud computing environment can include hundreds, thousands, or even millions, of virtual machines and other assets, owned or used by hundreds, thousands, or even millions, of parties and, in many cases, a given application or service can operate within, and interface with, multiple cloud computing environments. Consequently, detecting malware intrusion and extrusion is an extremely difficult and resource intensive task.
What is needed is a method and system for detecting and prioritizing malware intrusion and extrusion in cloud computing environments that makes use of existing cloud computing environment infrastructure, features, and assets.

Typically, trusted computing environments are those where the virtual and/or other assets and components, infrastructure, communication and networking systems, and security systems associated with the computing systems making up the trusted computing environment, are either under the control of, or known to, a party. In contrast, unknown, or untrusted computing environments are environments and systems where the virtual and/or other assets and components, infrastructure, communication and networking systems, and security systems implemented and associated with the computing systems making up the untrusted computing environment, are not under the control of, and/or are not known by, a party, and/or are dynamically configured with new elements capable of being added that are unknown to the party.
Examples of trusted computing environments include the virtual and/or other assets and components making up data centers associated with, and/or controlled by, a party and/or any computing systems, and/or networks of computing systems, associated with, known by, and/or controlled by, a party. Examples of untrusted computing environments include, but are not limited to, public networks, such as the Internet, various cloud-based computing environments, and various other forms of distributed computing systems.
In various embodiments, each computing environment includes allocated assets and virtual assets associated with, and controlled or used to create, and/or deploy, and/or operate an application.
It is often the case that a party desires to transfer data to, and/or from, a first computing environment that is an untrusted computing environment, such as, but not limited to, a public cloud, a virtual private cloud, and a trusted computing environment, such as, but not limited to, networks of computing systems in a data center controlled by, and/or associated with, the party. However, in other situations a party may wish to transfer data between two trusted computing environments, and/or two untrusted computing environments.
In one embodiment, two or more assets, such as computing systems and/or virtual assets, and/or two or more computing environments, are connected by one or more communications channels including but not limited to, Secure Sockets Layer communications channels and various other secure communications channels, and/or distributed computing system networks, such as, but not limited to: a public cloud; a private cloud; a virtual private network (VPN); a subnet; any general network, communications network, or general network/communications network system; a combination of different network types; a public network; a private network; a satellite network; a cable network; or any other network capable of allowing communication between two or more assets, computing systems, and/or virtual assets, as discussed herein, and/or available or known at the time of filing, and/or as developed after the time of filing.

FIG. 1 is a functional diagram of the interaction of various elements associated with one embodiment of the methods and systems for virtual asset assisted extrusion, and/or intrusion, detection in a cloud computing environment discussed herein. Of particular note, the various elements in FIG. 1 are shown for illustrative purposes as being associated with specific computing environments, such as computing environment 10, computing environment 11, computing environment 12, computing environment 13, computing environment 14, and computing environment 15. However, the exemplary placement of the various elements within these environments and systems in FIG. 1 is made for illustrative purposes only and, in various embodiments, any individual element shown in FIG. 1, or combination of elements shown in FIG. 1, can be implemented and/or deployed on any of one or more various computing environments or systems, and/or architectural or infrastructure virtual and/or other assets and components, such as one or more hardware systems, one or more software systems, one or more data centers, more or more clouds or cloud types, one or more third party service capabilities, or any other computing environments, architectural, and/or infrastructure virtual and/or other assets and components as discussed herein, and/or as known in the art at the time of filing, and/or as developed/made available after the time of filing.
In addition, the elements shown in FIG. 1, and/or the computing environments, systems and architectural and/or infrastructure virtual and/or other assets and components, deploying the elements shown in FIG. 1, can be under the control of, or otherwise associated with, various parties or entities, or multiple parties or entities, such as, but not limited to, the owner of a data center, a party and/or entity providing all or a portion of a cloud-based computing environment, the owner or a provider of a service, the owner or provider of one or more resources, and/or any other party and/or entity providing one or more functions, and/or any other party and/or entity as discussed herein, and/or as known in the art at the time of filing, and/or as made known after the time of filing.
In one embodiment, one or more cloud computing environments are provided. In various embodiments, the one or more cloud computing environments are used to create, and/or deploy, and/or operate an application that can be any form of cloud computing environment, such as, but not limited to, a public cloud; a private cloud; a virtual private network (VPN); a subnet; a Virtual Private Cloud (VPC); any security/communications grouping; or any other cloud-based infrastructure, sub-structure, or architecture, as discussed herein, and/or as known in the art at the time of filing, and/or as developed after the time of filing.
In many cases, a given application or service provided through a cloud computing infrastructure may utilize, and interface with, multiple cloud computing environments, including multiple VPCs, in the course of providing the associated service. As noted above, each cloud computing environment includes allocated virtual assets associated with, and controlled or used by, the party utilizing the cloud computing environment.
As used herein, the term “virtual asset” includes any virtualized entity or resource, and/or part of an actual, or “bare metal” entity requiring access to various resources, and types of resources. In various embodiments, the virtual assets can be, but are not limited to, virtual machines, virtual servers, and instances implemented in a cloud computing environment; databases implemented, or associated with, a cloud computing environment, and/or instances implemented in a cloud computing environment; services associated with, and/or delivered through, a cloud computing environment; communications systems used with, part of, or provided through, a cloud computing environment; and/or any other virtualized assets and/or sub-systems of “bare metal” physical devices such as mobile devices, remote sensors, laptops, desktops, point-of-sale devices, ATMs, electronic voting machines, etc. requiring access to various resources, and/or types of resources, located within a data center, within a cloud computing environment, and/or any other physical or logical location, as discussed herein, and/or as known/available in the art at the time of filing, and/or as developed/made available after the time of filing.
As discussed below, in one embodiment, virtual asset creation data is generated through a virtual asset creation system such as a virtual asset template through which the creator of a virtual asset can generate operational logic and assign resources and attributes to the virtual assets to be instantiated in a cloud computing environment, such as a virtual private cloud computing environment.
In one embodiment, a network communications device is included with each cloud computing environment provided. In one embodiment, outgoing message traffic sent from one or more of the virtual assets associated with a given cloud computing environment to a destination external to the cloud computing environment, such as the Internet, and/or incoming message traffic sent to one or more of the virtual assets associated with a given cloud computing environment from an origin external to the cloud computing environment, such as the Internet, is relayed through the network communications device for that cloud computing environment.
In various embodiments, the network communications devices for the cloud computing environment include, but are not limited to, one or more of a switching system, such as a network switch; a router; a border router; any gateway system; a firewall system; a load balancing system; a hypervisor; or any communication, relay, or routing system, as discussed herein, and/or as known in the art at the time of filing, and/or as developed after the time of filing, through which message traffic on a network communications channel to, or from, an external network, such as the Internet, is relayed, and/or routed, to one or more virtual assets in a cloud computing environment.
In one embodiment, the outgoing message traffic, and/or incoming message traffic, is relayed through the network communications device via at least one communications channel, e.g., a network communications channel, herein also referred to as a first communications channel.
As noted above, in various embodiments, the outgoing, and/or incoming, message traffic to, and/or from, the virtual assets associated with a given cloud computing environment are susceptible to the introduction of malware and, in particular, extrusion, and/or intrusion, related malware.
As also noted above, the fact that malware can be introduced into the cloud computing environment is a long standing problem. As also noted above, the introduction of malware into a virtual asset via one or more messages included in message traffic relayed by the network communications device, is known as intrusion. However, as also noted above, once introduced, some forms of malware take control of some, or all, of the infected virtual asset functionality and use the virtual asset to send outgoing messages and data through the message traffic relayed by the network communications device. This outbound malware mechanism is referred to as extrusion.
Consequently, the detection of both malware intrusion and extrusion is an important part of making cloud computing environments more secure. However, as also noted above, a given cloud computing environment, and/or VPC, can include hundreds, thousands, or even millions, of virtual assets, owned or used by hundreds, thousands, or even millions, of parties. Consequently, detecting malware intrusion and extrusion in a cloud computing environment is currently an extremely difficult and resource intensive task.
To address this issue, as discussed below, in one embodiment, one or more virtual assets within, and/or assigned to, a cloud computing environment are provided an analysis trigger monitoring system.
In one embodiment, by virtue of the addition of the analysis trigger monitoring system logic to one or more of the one or more virtual assets in the cloud computing environment, the one or more virtual assets in the cloud computing environment provided an analysis trigger monitoring system are transformed into extrusion, and/or intrusion, detection capable virtual assets for the cloud computing environment.
In various embodiments, the analysis trigger monitoring system is a module of software and/or logic implemented in, or on, the one or more virtual assets and capable of monitoring at least a portion of the message traffic to, and/or between, and/or from, one or more virtual assets instantiated in the cloud computing environment.
In various embodiments, the methods and systems for intrusion and extrusion detection discussed herein are applied to network communications, e.g., message traffic, which is in plain text or is encrypted. Consequently, in some embodiments, the analysis trigger monitoring system, and/or the network communications device, and/or the extrusion, and/or intrusion, detection capable virtual assets include a decryption capability to decrypt outgoing and incoming message traffic as part of the monitoring and analysis. In other embodiments, a decryption capability is provided to decrypt outgoing and incoming message traffic prior to being provided to analysis trigger monitoring system and any monitoring and analysis.
As discussed below, in some embodiments, the analysis trigger monitoring system allows for analysis policies to be added, or removed, dynamically based on alerts that are received.
Referring to FIG. 1, cloud computing environment 11 is shown, along with illustrative computing environments 10, 12, 13, 14, and 15. Herein, cloud computing environment 11 and computing environments 10, 12, 13, 14, and 15 are referred to collectively as computing environments 10, 11, 12, 13, 14, and 15.
Also shown in FIG. 1 is Internet 101 that, in this specific illustrative example, is the origin, and/or destination, external to cloud computing environment 11. As seen in FIG. 1, Internet 101 is communicatively coupled to cloud computing environment 11 via network communications channel 114 and network communications device 115, shown in this illustrative example as implemented computing environment 10.
As seen in FIG. 1, Internet 101 is communicatively coupled to network communications device 115, through which message traffic to, and from, representative extrusion detection capable virtual asset 125 and representative intrusion detection capable virtual asset 135 in cloud computing environment 11 is relayed via network communications channel 114, also referred to herein as the first communications channel.
As seen in FIG. 1, network communications device 115 is shown as implemented in computing environment 10 that is distinct from computing environment 11 of representative extrusion detection capable virtual asset 125 and representative intrusion detection capable virtual asset 135. However, as noted above, this illustrative placement of network communications device 115 is not limiting and, in other embodiments, network communications device 115 can be implemented in any of computing environments 10, 11, 12, 13, 14, and 15.
As also seen in FIG. 1, representative extrusion detection capable virtual asset 125 and representative intrusion detection capable virtual asset 135 are provided with analysis trigger monitoring system 127 and analysis trigger monitoring system 137, respectively. Those of skill in the art will readily recognize that while a single representative example of an extrusion detection capable virtual asset, i.e., extrusion detection capable virtual asset 125, is shown in FIG. 1, extrusion detection capable virtual asset 125 is representative of any number of extrusion detection capable virtual assets that can be created and instantiated in cloud computing environment 11. Likewise, while a single representative example of an intrusion detection capable virtual asset, i.e., intrusion detection capable virtual asset 135, is shown in FIG. 1, intrusion detection capable virtual asset 135 is representative of any number of intrusion detection capable virtual assets that can be created and instantiated in cloud computing environment 11.
In addition, in various embodiments, only extrusion detection capable virtual assets are created and instantiated in cloud computing environment 11, and/or only intrusion detection capable virtual assets are instantiated in cloud computing environment 11, and/or a mix of extrusion detection capable virtual assets and intrusion detection capable virtual assets are created and instantiated in cloud computing environment 11.
In addition, in various embodiments, extrusion detection capable virtual asset 125 can include intrusion detection capabilities and intrusion detection capable virtual asset 135 can include extrusion detection capabilities. Consequently, in various embodiments, extrusion detection capable virtual asset 125 and intrusion detection capable virtual asset 135 are similar, or identical, extrusion/intrusion detection capable virtual assets.
As discussed above, in one embodiment, virtual asset creation data is generated through a virtual asset creation system such as a virtual asset template through which the creator of a virtual asset can generate operational logic and assign resources and attributes to the virtual assets to be instantiated in a cloud computing environment.
Referring to FIG. 2B, a functional diagram is shown of part of the operational logic of an extrusion/intrusion detection capable virtual asset creation template 240 for creating an extrusion, and/or intrusion, detection capable virtual asset, such as extrusion detection capable virtual asset 125 and/or intrusion detection capable virtual asset 135 of FIG. 1, in accordance with one embodiment.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes primary virtual asset data 243 which, in one embodiment, includes at least part of primary virtual asset data associated with the virtual asset itself, and/or the operation of the virtual asset, and/or the operating environment of the virtual asset.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes primary virtual asset data transfer logic 245 which is used to transfer a copy of at least part of the primary virtual asset data from the virtual asset to a virtual asset validation system.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes virtual asset launch sequence logic 247 for launching the virtual asset in a given computing environment and indicating the launch sequence and protocols to be used to launch the virtual asset and to be applied at launch.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes analysis trigger data 249 which, as discussed below, includes machine-readable analysis trigger data representing analysis trigger parameters. In one embodiment, the analysis trigger parameters are defined such that if one or more of the one or more analysis trigger parameters are detected in a message to, or from, the virtual asset, then that message is deemed a suspect message that is potentially associated with an intrusion or extrusion attack on the virtual asset, and/or the cloud computing environment. In various embodiments, the analysis trigger parameters of analysis trigger data 249 can be dynamically added, removed, and/or modified to reflect various policies, and/or policy changes made in response to malware alerts.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes message data 251 including at least part of the message data associated with at least some of the message traffic to, and/or from, the extrusion, and/or intrusion, detection capable virtual asset.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes analysis trigger monitoring logic 253 which, as discussed below, uses the analysis trigger parameters of analysis trigger data 249 to monitor message data 251 representing at least part of the message data associated with at least some of the message traffic to, and/or from, virtual assets relayed by the network communications device to detect one or more of the one or more analysis trigger parameters within the message data.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes suspect message copy generation logic 255 which, as discussed below, is used to generate, for each detected suspect message, suspect message copy data representing a copy of at least part of the message data making up the suspect message detected in message data 251 by analysis trigger monitoring logic 253.
As seen in FIG. 2B, in one embodiment, extrusion/intrusion detection capable virtual asset creation template 240 includes suspect message copy transfer logic 257 which, as discussed below, is used to transfer the suspect message copy data of suspect message copy generation logic 255 to one or more analysis systems for further analysis in an “off-line” environment.
In one embodiment, one or more analysis trigger parameters are defined such that if one or more of the one or more analysis trigger parameters are detected in a message to, or from, a virtual asset, then that message is deemed a suspect message that is potentially associated with an intrusion or extrusion attack on the virtual asset, and/or the cloud computing environment.
In various embodiments, the analysis trigger parameters can be dynamically added, removed, and/or modified to reflect various policies, and/or policy changes made in response to malware alerts.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, the presence of an IP address in a message indicating a designated suspect origin or destination. In one embodiment, this analysis trigger parameter is used to detect messages coming from, or going to, a designated suspicious entity that is suspected of being associated with malware. In various embodiments, the IP addresses associated with designated suspicious entities, and/or the identity of the entities themselves, is provided by one or more third parties via alerts or other mechanisms.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, the presence of an IP address in a message indicating a designated suspect geographical region. In one embodiment, this analysis trigger parameter is used to detect messages coming from, or going to, geographical locations that are known to be associated with malware. In various embodiments, the geographical locations known to be associated with malware are provided by the one or more third parties via alerts or other mechanisms.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, the presence of an IP address in a message indicating an origin or destination that is not included on a list of authorized, or expected, origins or destinations of messages to be received by, or transmitted from, the virtual assets. In one embodiment, this analysis trigger parameter is used to detect message traffic that would not be expected to be generated in the normal course of operation of the virtual assets according to their operational mission.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, the presence of an IP address in a message indicating a geographical location that is not included on a list of authorized, or expected, geographical locations to be associated with messages to be received by, or transmitted from, and the virtual assets. In one embodiment, this analysis trigger parameter is used to detect message traffic that would not be expected to be generated in the normal course of operation of the virtual assets according to their operational instructions.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, setting a threshold maximum message size and determining that a given message is of a size exceeding the threshold maximum message size. In one embodiment, this analysis trigger parameter takes advantage of the fact that many forms of malware require message sizes larger than those normally associated with a given virtual asset in order to deliver the malware necessary to execute the malicious intent.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, setting a threshold minimum message size and determining that a given message is of a size that is less than the threshold minimum message size. In one embodiment, this analysis trigger is used to detect messages of a size that is smaller than a message size determined to be typical with respect to a given virtual asset, and that are therefore suspicious.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, analysis trigger parameters based on frequency analysis of the access pattern indicating that messages arrive too frequently or too infrequently.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, a hash value of at least part of the message data that is not included in a list of allowed hash values. In one embodiment, this analysis trigger parameter is used in conjunction with a hash-based analysis of at least part of a given message being sent to, and/or transmitted from, a virtual asset. In one embodiment, allowable hash values are defined and then a hash is performed on at least part of a given message. In one embodiment, if the hash of the portion of the given message does not match any of the allowed hash values, the message is determined to be suspect.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, an MD5 value of the message data that is not included in a list of allowed MD5 values.
MD5 (Message-Digest algorithm five) is a widely used cryptographic hash function producing a 128 bit (16 byte) hash value that is typically expressed as a 32 digit hexadecimal number. In one embodiment, the MD5 algorithm is applied to at least part of the message data associated with a given message and the resulting MD5 value is compared with a list of allowed MD5 values. If the resulting MD5 value does not match any of the allowed MD5 values, then the message is considered suspect.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, the specific identity of the sender of the message and adding the ability to have a per-message offline analysis that determines whether to trigger a message as suspect. In one embodiment, the analysis can be in-line or asynchronously off-line and would typically miss an initial or first example of an intrusion or extrusion message but would be used for other “like messages” where the criteria for “like” is an analysis trigger parameter that can be dynamically installed in the trigger monitoring system. Consequently, in one embodiment, new analysis trigger parameters are discovered and applied heuristically to create a self-learning extrusion and/or intrusion detection system.
In various embodiments, specific examples of analysis trigger parameters include, but are not limited to, the specific identity of the recipient of the message and adding the ability to have a per-message offline analysis that determines whether to trigger a message as suspect. In one embodiment, the analysis can be in-line or asynchronously off-line and would typically miss an initial or first example of an intrusion or extrusion message but would be used for other “like messages” where the criteria for “like” is an analysis trigger parameter that can be dynamically installed in the trigger monitoring system. Consequently, in one embodiment, new analysis trigger parameters are discovered and applied heuristically to create a self-learning extrusion and/or intrusion detection system.
In various other embodiments, any other analysis trigger parameter, or combination of analysis trigger parameters, as discussed herein, and/or as known in the art at the time of filing, and/or as developed after the time of filing is/are defined.
In one embodiment, once the analysis trigger parameters are defined, machine-readable analysis trigger data is generated representing the analysis trigger parameters.
In one embodiment, all, or part, of the analysis trigger data is provided to the analysis trigger monitoring systems associated with the extrusion, and/or intrusion, detection capable virtual assets.
In one embodiment, the analysis trigger data and the analysis trigger monitoring systems are then used to monitor at least part of the message data associated with at least some of the message traffic to, and/or from, the virtual assets relayed by the network communications device. In one embodiment, at least part of the message data associated with at least some of the message traffic to, and/or from, the extrusion, and/or intrusion, detection capable virtual assets is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, the part of the message data associated with at least some of the message traffic from the extrusion, and/or intrusion, detection capable virtual assets is decrypted by a decryption capability associated with the analysis trigger monitoring system, and/or the network communications device, and/or the extrusion, and/or intrusion, detection capable virtual assets before the analysis trigger data and the analysis trigger monitoring systems are used to monitor at least part of the message data associated with at least some of the message traffic to and/or from the extrusion, and/or intrusion, detection capable virtual assets.
In one embodiment, if one or more of the one or more analysis trigger parameters is detected within the message data associated with a given message, the classification data associated with that message is transformed into classification data indicating that the detected message including one or more of the one or more analysis trigger parameters is a suspect message.
Returning to FIG. 1, analysis trigger monitoring system 127 is shown implemented in extrusion detection capable virtual asset 125 and analysis trigger monitoring system 137 is shown implemented in intrusion detection capable virtual asset 135. Referring now to FIG. 2A, cloud computing environment 11 is shown in more detail.
As seen in FIG. 2A, Internet 101 is communicatively coupled to cloud computing environment 10 and network communications device 115. As seen in FIG. 2A, analysis trigger monitoring system 127 is implemented in extrusion detection capable virtual asset 125 in cloud computing environment 11 and includes analysis trigger monitor 215 and matching engine 216 commutatively coupled to network communications channel 114. As seen in FIG. 2A, network communications channel 114 relays message data 209 to, and/or from, extrusion detection capable virtual asset 125.
As also seen in FIG. 2A, analysis trigger data 213, representing defined analysis trigger parameters, is shown as second input data to matching engine 216 of analysis trigger monitor 215.
In one embodiment, the detected suspect messages are temporarily permitted to be transmitted to, and/or from, the virtual assets through the network communications channel, i.e. the first communications channel, with minimal delay. In one embodiment, these transmissions are permitted in order to avoid significantly disrupting or delaying the transmission of messages without further evidence that the suspect messages are indeed malicious. However, for each detected suspect message, suspect message copy data is generated representing a copy of at least part of the message data making up the suspect message.
Consequently, in one embodiment, the analysis performed by the analysis trigger monitoring systems can be performed in-line or asynchronously off-line on a per-message basis that would then miss an initial or first example of an intrusion or extrusion message but would be used for other “like messages” where the criteria for “like” is an analysis trigger parameter that can be dynamically installed in the trigger monitoring systems.
In one embodiment, for each detected suspect message, the at least part of the message data making up the suspect message is decrypted and decrypted suspect message copy data is generated representing a decrypted copy of at least part of the message data making up the suspect message.
In one embodiment, the suspect message copy data is then transmitted to one or more analysis systems for further analysis in an “off-line” environment. In one embodiment, the suspect message copy data is transmitted to the one or more analysis systems via a message analysis communication channel, also referred to herein as a second communications channel, that is distinct from the network communications channel, i.e., the first communications channel through which messages are relayed to, and/or from, the virtual assets via the network communications device. In this way, the transmission of the suspect message copy data, and the subsequent message data analysis, does not affect the operation of the virtual assets, and/or the operation of the cloud computing environment associated with the virtual assets.
As seen in FIG. 1, message copy data 129 is sent from extrusion detection capable virtual asset 125 to threat scoring service 151, illustratively shown in computing environment 14 in FIG. 1, via threat scoring channel 150, also referred to as a second communications channel. Likewise, message copy data 139 is sent from intrusion detection capable virtual asset 135 to threat scoring service 181, illustratively shown in computing environment 15 in FIG. 1, via threat scoring channel 180, also referred to as a second communications channel.
As seen in FIG. 2A, in one embodiment, when message copy data 129 is provided to threat scoring service 151, it is provided to threat scoring engine 155. In one embodiment, threat scoring engine 155 generates threat score data 153. In one embodiment, threat score data 153 is generated by threat scoring service 151 and indicates the results of the analysis of the message copy data 129 by threat scoring engine 155.
In one embodiment, threat scoring service 151 determines threat patterns for potential security threats using any one of a number of techniques. In one embodiment, threat scoring service 151 requests and receives security threat patterns from an information management security service provider or vendor. Threat scoring service 151 then updates a security threat pattern database with the received security threat patterns. In another embodiment, computing security analysts manually update the security threat pattern database through threat scoring service 151 after compiling, reverse-engineering, or otherwise analyzing traffic patterns between a malicious computing device and a service provider. For example, computing security analysts can simulate and monitor traffic patterns between a test computing system and a test asset hosting a test online service by configuring the test computing system to send or execute security threats on the test online service. Based on the traffic patterns monitored from the simulation, the analysts can determine and record particular patterns that are associated with particular types of security threats. In some embodiments, the types of threats for which security threat patterns are stored in the security threat pattern database include, but are not limited to, spoofing, tampering, repudiation, information disclosure, denial of service, and/or elevation of privilege, among others.
Threat scoring service 151 can determine threat patterns or potential security threats by establishing baseline time limits for the reasonable execution of one or more APIs associated with a virtual asset. For example, threat scoring service 151 can cause a virtual asset to execute a sample program that cycles through one or more APIs of the virtual asset. During the execution of the sample program. Threat scoring service 151 monitors the execution of the APIs and establishes minimum time delays that are likely to occur or that should occur during normal and/or non-malicious communications with the virtual asset, according to one embodiment. Threat scoring service 151 can then record, create, or determine baseline or normal traffic patterns for the service traffic and can determine or define deviations from the baseline as security threat patterns, according to one embodiment. In some embodiments, threat scoring service 151 defines login failure patterns based on APIs associated with login attempts, so that excessive attempts and excessively short delays between successive attempts to login can be flagged as security threat patterns. In some embodiments, the patterns include, but are not limited to, time references, such as “FAST,” “SLOW,” “LONG,” “SHORT,” “QUICK,” “MEDIUM,” “VERY SLOW,” “VERY FAST,” or the like. In other embodiments, the patterns include, but are not limited to, bandwidth references and/or payload size references, such as, “SMALL,” “MEDIUM,” “LARGE,” “VERY LARGE,” or the like.
Threat scoring service 151 can also determine defined anti-patterns, in one embodiment. By evaluating normal execution patterns of APIs for the virtual asset for extended periods of time, threat scoring service 151 can develop a sizable library in the threat scoring service 151 of reasonable, allowable, and/or “normal” API execution sequences. Threat scoring service 151 can then define any traffic patterns that do not fit within the predetermined model as a subset of security threat patterns, i.e., anti-patterns. When an anti-pattern occurs, threat scoring service 151 can flag or identify service traffic associated with the anti-pattern as being potentially malicious, according to one embodiment.
In one embodiment, threat score data 153 is provided to extrusion detection capable asset 125 via threat scoring channel 140, also referred to as a second communications channel. Turning back to FIG. 1, in one embodiment, threat score data 183 is generated by threat scoring service 181. In one embodiment, threat score data 183 is provided to intrusion detection capable virtual asset 135 via threat scoring channel 190, also referred to as a second communications channel.
In FIG. 1, threat scoring service 151 is illustratively shown as being implemented in computing environment 14. As noted above, the implementation of threat scoring service 151 in computing environment 14 is shown for illustrative purposes only and, in other embodiments, threat scoring service 151 could be implemented in computing environment 10, or computing environment 11, or computing environment 12, or computing environment 13, or computing environment 15, or partially implemented in any one or more of computing environment 10, computing environment 11, computing environment 12, computing environment 13, computing environment 14, and computing environment 15.
In one embodiment, threat scoring services, such as representative threat scoring services 151 and 181, are provided that are specifically implemented to analyze specific analysis trigger parameters. Consequently, in one embodiment, the particular threat scoring service to which a given example of suspect message data is transmitted is determined, at least in part, by the specific analysis trigger parameter detected in the suspect message from which the suspect message copy data was derived. Consequently, in one embodiment, the matching trigger data is used, at least in part, to determine which analysis system, such as representative threat scoring service 151, of one or more specialized analysis systems (not shown) is to receive message copy data 129 via message analysis channel 160.
In various embodiments, threat scoring services, services, such as representative threat scoring services 151 and 181, provide threat score data, such as representative threat score data 153 and 183 to extrusion/intrusion detection capable virtual assets such as representative extrusion detection capable virtual asset 125 and intrusion detection capable virtual asset 135 at various frequencies. In one embodiment, threat score data is transmitted to the extrusion/intrusion detection capable virtual assets on a periodic basis in digests, rather than in real time. In some embodiments, threat score data representing less significant potential threats are periodically transmitted to extrusion/intrusion detection capable virtual assets, e.g., on a weekly, semi-monthly, or monthly basis. In one embodiment, threat score data representing significant threats are immediately transmitted to the extrusion/intrusion detection capable virtual assets.
As seen in FIG. 1, message copy data 129 is sent from extrusion detection capable virtual asset 125 to analysis system 161, illustratively shown in computing environment 12 in FIG. 1, via message analysis channel 160, also referred to as a third communications channel. Likewise, message copy data 139 is sent from intrusion detection capable virtual asset 135 to analysis system 171, illustratively shown in computing environment 13 in FIG. 1, via message analysis channel 170, also referred to as a third communications channel.
Referring back to FIG. 1 and FIG. 2A together, if analysis trigger monitor 215 detects one of the analysis trigger parameters of analysis trigger data 213 in message data 209, message data 209 is classified as suspect message data and this information is provided to message copy generation module 220 where suspect message copy data, represented in FIG. 1 by message copy data 129, is generated and transmitted to analysis system 161, i.e., a malware detection and analysis system, via message analysis channel 160 that is distinct from network communications channel 114.
In one embodiment, message copy data 129 is then provided to analysis module 163 of analysis system 161. As seen in FIG. 1, analysis system 161 is illustratively shown as being implemented in computing environment 12. As noted above, the implementation of analysis system 161 in computing environment 12 is shown for illustrative purposes only and, in other embodiments, analysis system 161 could be implemented in computing environment 10, or computing environment 11, or computing environment 13, or computing environment 14, or computing environment 15, or partially implemented in any of computing environment 10, computing environment 11, computing environment 12, and computing environment 13.
In one embodiment, results data 165 is generated by analysis system 161 indicating the results of the analysis of the message copy data 129 by analysis module 163.
In one embodiment, multiple analysis systems, such as representative analysis systems 161 and 171, are provided that are specifically implemented to analyze specific analysis trigger parameters. Consequently, in one embodiment, the particular analysis system to which a given example of suspect message data is transmitted is determined, at least in part, by the specific analysis trigger parameter detected in the suspect message from which the suspect message copy data was derived. Consequently, in one embodiment, the matching trigger data is used, at least in part, to determine which analysis system, such as representative analysis system 161, of one or more specialized analysis systems (not shown) is to receive message copy data 129 via message analysis channel 160.
In one embodiment, if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems, it is determined that the suspect message is indeed associated with an intrusion or extrusion attack, one or more systems, entities, and/or parties, are alerted to the situation so that appropriate protective action can be taken.
In one embodiment, if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems, it is determined that the suspect message is indeed associated with an intrusion or extrusion attack, one or more protective actions are automatically taken to prevent further infection of the virtual assets, and/or other virtual assets, and/or the application, service, infrastructure, or computing environment, associated with the now identified infected virtual asset.
In various embodiments, the protective actions taken can include, but are not limited to, isolating the virtual asset such that the virtual asset can still continue to operate, but in total isolation of all other virtual assets; partially isolating the virtual asset such that the virtual asset is allowed to connect to some very specific virtual assets, but has most of its communication channels blocked; “killing” or terminating the virtual asset; repairing the virtual asset by re-loading the compromised sub-components of the virtual asset; and/or any other protective actions, or combination of protective actions, discussed herein, and/or as known in the art at the time of filing, and/or as developed, or become known, after the time of filing.
Using the methods and systems for virtual asset assisted extrusion, and/or intrusion, detection in a cloud computing environment discussed above, intrusion and extrusion attacks in cloud computing environments can be detected using largely existing cloud computing environment infrastructure, such as modified virtual assets with added analysis trigger monitoring systems; without the need for devoting extensive and/or specialized resources. Consequently, using the method and system for virtual asset assisted extrusion, and/or intrusion, detection in a cloud computing environment, intrusion and extrusion events can be efficiently and effectively detected; thereby making distributed computing environments, such as cloud computing environments, more secure.
Process
In accordance with one embodiment, a process for virtual asset assisted extrusion detection in a cloud computing environment includes providing a cloud computing environment. In one embodiment, the cloud computing environment includes one or more virtual assets. In one embodiment, one or more of the one or more virtual assets in the cloud computing environment is provided an analysis trigger monitoring system; thereby transforming the one or more virtual assets in the cloud computing environment provided an analysis trigger monitoring system into extrusion detection capable virtual assets for the cloud computing environment. In one embodiment, one or more analysis trigger parameters are defined and analysis trigger data representing the analysis trigger parameters is generated. In one embodiment, the analysis trigger data is provided to the analysis trigger monitoring systems of the extrusion detection capable virtual assets. The analysis trigger monitoring systems and the analysis trigger data are then used to monitor at least a portion of the message traffic sent from the virtual assets in the cloud computing environment to detect any message including one or more of the one or more analysis trigger parameters.
In one embodiment, any detected message including one or more of the one or more analysis trigger parameters is identified as a suspect message and, for each suspect message, suspect message copy data representing a copy of at least a portion of the suspect message is generated. In one embodiment, the suspect message copy data is then transferred to one or more analysis systems for further analysis.
FIG. 3 is a flow chart of a process 300 for virtual asset assisted extrusion detection in a cloud computing environment in accordance with one embodiment. In one embodiment, process 300 for virtual asset assisted extrusion detection in a cloud computing environment begins at ENTER OPERATION 301 of FIG. 3 and process flow proceeds to PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303.
In one embodiment, at PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 a cloud computing environment is provided.
In various embodiments, the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 can be any form of cloud computing environment, such as, but not limited to, a Virtual Private Cloud, or VPC.
In many cases, a given application or service provided through a cloud computing environment may utilize, and interface with, multiple cloud computing environments, including multiple VPCs, in the course of providing the associated service. As noted above, each cloud computing environment includes allocated virtual assets associated with, and controlled or used by, the party utilizing the cloud computing environment.
As used herein, the term “virtual asset” includes any virtualized entity or resource, and/or part of an actual, or “bare metal” entity requiring access to various resources, and types of resources. In various embodiments, the virtual assets can be, but are not limited to, virtual machines, virtual servers, and instances implemented in a cloud computing environment; databases implemented, or associated with, a cloud computing environment, and/or instances implemented in a cloud computing environment; services associated with, and/or delivered through, a cloud computing environment; communications systems used with, part of, or provided through, a cloud computing environment; and/or any other virtualized assets and/or sub-systems of “bare metal” physical devices such as mobile devices, remote sensors, laptops, desktops, point-of-sale devices, ATMs, electronic voting machines, etc. requiring access to various resources, and/or types of resources, located within a data center, within a cloud computing environment, and/or any other physical or logical location, as discussed herein, and/or as known/available in the art at the time of filing, and/or as developed/made available after the time of filing.
In one embodiment, virtual asset creation data is generated through a virtual asset creation system such as a virtual asset template through which the creator of a virtual asset can generate operational logic and assign resources and attributes to the virtual assets to be instantiated in a cloud computing environment, such as a virtual private cloud computing environment.
In one embodiment, once a cloud computing environment is provided at PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303, process flow proceeds to PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305.
In one embodiment, at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 a network communications device is provided for each cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303.
In various embodiments, the network communications devices of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 provided for the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 include, but are not limited to, one or more of a switching system, such as a network switch; a router; a border router; any gateway system; a firewall system; a load balancing system; a hypervisor; or any communication, relay, or routing system, as discussed herein, and/or as known in the art at the time of filing, and/or as developed after the time of filing, through which message traffic on a network communications channel to, or from, an external network, such as the Internet, is relayed, and/or routed, to one or more virtual assets in a cloud computing environment.
In one embodiment, outgoing message traffic sent from one or more of the virtual assets associated with a given cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 to a destination external to the cloud computing environment, such as the Internet, is relayed through the network communications device for that cloud computing environment of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305.
In one embodiment, the outgoing message traffic is relayed through the network communications device of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 via at least one communications channel, e.g., a network communications channel, herein also referred to as a first communications channel.
As noted above, in various embodiments, the outgoing message traffic from the virtual assets associated with a given cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 are susceptible to the introduction of malware and, in particular, extrusion related malware.
As also noted above, the fact that malware can be introduced into the cloud computing environments of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 is a long standing problem. As also noted above, some forms of malware take control of some, or all, of the infected virtual asset functionality and use the virtual asset to send outgoing messages and data through the message traffic relayed by the network communications device. This outbound malware mechanism is referred to as extrusion.
Consequently, the detection of malware extrusion is an important part of making the cloud computing environments of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 more secure. However, as also noted above, a given cloud computing environment, and/or virtual private cloud computing environment, can include hundreds, thousands, or even millions, of virtual assets, owned or used by hundreds, thousands, or even millions, of parties. Consequently, detecting malware extrusion in a cloud computing environment is currently an extremely difficult and resource intensive task.
To address this issue, in one embodiment, at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 one or more virtual assets within, and/or assigned to, the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 are provided an analysis trigger monitoring system.
In one embodiment, by virtue of the addition of the analysis trigger monitoring system logic to one or more of the one or more virtual assets in the cloud computing environment at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305, the one or more virtual assets in the cloud computing environment provided an analysis trigger monitoring system are transformed into extrusion detection capable virtual assets for the cloud computing environment.
In various embodiments, the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 is a module of software and/or logic implemented in, or on, the one or more virtual assets and capable of monitoring at least a portion of the message traffic from one or more virtual assets instantiated in the cloud computing environment.
In various embodiments, process 300 for virtual asset assisted extrusion detection in a cloud computing environment is applied to network communications, e.g., message traffic, which is in plain text or is encrypted. Consequently, in some embodiments, the analysis trigger monitoring system, and/or the network communications device, and/or the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 include a decryption capability to decrypt outgoing message traffic as part of the monitoring and analysis. In other embodiments, a decryption capability is provided to decrypt outgoing message traffic prior to being provided to analysis trigger monitoring system and any monitoring and analysis.
As discussed below, in some embodiments, the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 allows for analysis policies to be added, or removed, dynamically based on alerts that are received.
In one embodiment, once one or more virtual assets within, and/or assigned to, the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303 are provided an analysis trigger monitoring system at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305, process flow proceeds to DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307.
In one embodiment, at DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 one or more analysis trigger parameters are defined such that if one or more of the one or more analysis trigger parameters are detected in a message from a virtual asset, then that message is deemed a suspect message that is potentially associated with an extrusion attack on the virtual asset, and/or the cloud computing environment.
In various embodiments, the analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 can be dynamically added, removed, and/or modified to reflect various policies, and/or policy changes, made in response to malware alerts. In addition, as discussed below, in one embodiment, analysis trigger parameters are applied heuristically and new analysis trigger parameters that are discovered by the application of process 300 for virtual asset assisted extrusion detection in a cloud computing environment are added to create a self-learning extrusion detection system.
In various embodiments, specific examples of analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 include, but are not limited to, the presence of an IP address in a message indicating a designated suspect destination. In one embodiment, this analysis trigger parameter is used to detect messages going to a designated suspicious entity that is suspected of being associated with malware.

In one embodiment, this analysis trigger is used to detect messages that are smaller than a message size determined to be typical with respect to a given virtual asset, and that are therefore suspicious.

In one embodiment, this analysis trigger parameter is used in conjunction with a hash-based analysis of at least part of a given message being transmitted from a virtual asset. In one embodiment, allowable hash values are defined and then a hash is performed on at least part of a given message. In one embodiment, if the hash of the portion of the given message does not match any of the allowed hash values, the message is determined to be suspect.
In various embodiments, specific examples of analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 include, but are not limited to, an MD5 value of the message data that is not included in a list of allowed MD5 values.
MD5 (Message-Digest algorithm five) is a widely used cryptographic hash function producing a 128 bit (16 byte) hash value that is typically expressed as a 32 digit hexadecimal number. In one embodiment, the MD5 algorithm is applied to at least part of the message data associated with a given message and the resulting MD5 value is compared with a list of allowed MD5 values. If the resulting MD5 value does not match any of the allowed MD5 values, then the message is considered suspect.
In various embodiments, specific examples of analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 include, but are not limited to, the specific identity of the sender of the message and adding the ability to have a per-message offline analysis that determines whether to trigger a message as suspect. In one embodiment, the analysis can be in-line or asynchronously off-line and would typically miss an initial or first example of an extrusion message but would be used for other “like messages” where the criteria for “like” is an analysis trigger parameter that can be dynamically installed in the trigger monitoring system. In addition, as discussed below, in one embodiment, analysis trigger parameters are applied heuristically and new analysis trigger parameters that are discovered by the application of process 300 for virtual asset assisted extrusion detection in a cloud computing environment are added to create a self-learning extrusion detection system.

In one embodiment, at PROVIDE THE ANALYSIS TRIGGER DATA TO THE ANALYSIS TRIGGER MONITORING SYSTEMS OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 311 at least part of the analysis trigger data of GENERATE ANALYSIS TRIGGER DATA REPRESENTING THE ANALYSIS TRIGGER PARAMETERS OPERATION 309 is provided to the analysis trigger monitoring systems of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305.
In one embodiment, once at least part of the analysis trigger data of GENERATE ANALYSIS TRIGGER DATA REPRESENTING THE ANALYSIS TRIGGER PARAMETERS OPERATION 309 is provided to the analysis trigger monitoring systems of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 at PROVIDE THE ANALYSIS TRIGGER DATA TO THE ANALYSIS TRIGGER MONITORING SYSTEMS OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 311, process flow proceeds to USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313.

In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 the at least part of the message data associated with at least some of the message traffic from the extrusion detection capable virtual assets is decrypted by the decryption capability associated with the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 before the analysis trigger data of GENERATE ANALYSIS TRIGGER DATA REPRESENTING THE ANALYSIS TRIGGER PARAMETERS OPERATION 309 and the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 are used to monitor at least part of the message data associated with at least some of the message traffic from the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 a sample part of the message data associated with at least some of the message traffic from at least some of the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 all of the message data from at least some of the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 at least part of the message data from all of the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 all of the message data associated with all of the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, the analysis of USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 is performed by the analysis trigger monitoring systems in-line, or asynchronously off-line, on a per-message basis. Consequently, in some embodiments, an initial or first example of an extrusion message is passed through a given extrusion detection capable virtual asset but would be used to stop other “like messages” where the criteria for “like” is an analysis trigger parameter that can be dynamically installed in the trigger monitoring system.
In addition, in one embodiment, analysis trigger parameters are applied heuristically at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 and new analysis trigger parameters that are discovered by the application of process 300 for virtual asset assisted extrusion detection in a cloud computing environment are added to create a self-learning extrusion detection system.
In one embodiment, once the analysis trigger data of GENERATE ANALYSIS TRIGGER DATA REPRESENTING THE ANALYSIS TRIGGER PARAMETERS OPERATION 309 and the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 are used to monitor at least part of the message data associated with at least some of the extrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 305 at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313, process flow proceeds to CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315.
In one embodiment, at CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315, if one or more of the one or more analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 is detected within the message data associated with a given message, the classification data associated with that message is transformed into classification data indicating that the detected message including one or more of the one or more analysis trigger parameters is a suspect message.
In one embodiment, once the classification data associated with messages having one or more of the one or more analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307 is transformed into classification data indicating that the detected message including one or more of the one or more analysis trigger parameters is a suspect message at CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315, process flow proceeds to ASSIGN A THREAT SCORE TO THE SUSPECT MESSAGE AT LEAST PARTIALLY BASED ON A POTENTIAL IMPACT OF THE SUSPECT MESSAGE'S POTENTIAL SECURITY THREAT ON THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET OPERATION 317. In one embodiment, at ASSIGN A THREAT SCORE TO THE SUSPECT MESSAGE AT LEAST PARTIALLY BASED ON A POTENTIAL IMPACT OF THE SUSPECT MESSAGE'S POTENTIAL SECURITY THREAT ON THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET OPERATION 317, a threat score is assigned to the suspect message based, at least partially, on a potential impact of the suspect message's potential security threat on the extrusion detection capable virtual asset.
For example, if the potential security threat can compromise financial data, e.g., credit card information of users, the threat score will be higher than if the potential security threats cause minor decreases in network connectivity speeds, according to one embodiment. To determine the potential impact of the potential security threat, the process evaluates the context of the potential security threat. In other words, the process evaluates the characteristics of the extrusion detection capable virtual asset, the type of threat, the likelihood of success of the threat, and the like.
In one embodiment, a threat score is assigned to the suspect message based on the relative impact of a potential security threat to the extrusion detection capable virtual asset. For example, based on the impact of the potential security threat, a numerical score can be assigned to the suspect message. For example, a score of 10 can be assigned to suspect messages having potential security threats with the highest probability of successful attack and that acquire personal data of users of the extrusion detection capable virtual asset. A 0 (zero) can be assigned to suspect messages having potential security threats with the lowest probability of successful attack and/or that are likely to have a negligible effect on the performance of the extrusion detection capable virtual asset, according to one embodiment. Various factors, such as asset configuration, number of subscribers, security features developed into the extrusion detection capable virtual asset, notification of new security threats or external risks, or input from a third party vulnerability scanner, can provide context while assessing a potential security threat and assigning a threat score. In some embodiments, the threat scores range from 0 to 10. In other embodiments, the threat scores range from 0 to 100. In yet other embodiments, the threat scores include values or indicators such as, “LOW,” “MEDIUM,” and “HIGH.” In one embodiment, the threat scores can include color coordinating so that high priority potential security threats are a first color such as red, low priority potential security threats are a second color different from the first color, such as orange, and the absence of potential security threats is indicated with a third color different from the first and second colors, such as green. As those of skill in the art will appreciate, other scoring ranges or values can be used while assigning a threat score to a suspect message having a potential security threat, according to various embodiments.
In one embodiment, once a threat score is assigned to the suspect message at ASSIGN A THREAT SCORE TO THE SUSPECT MESSAGE AT LEAST PARTIALLY BASED ON A POTENTIAL IMPACT OF THE SUSPECT MESSAGE'S POTENTIAL SECURITY THREAT ON THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET OPERATION 317, process flow proceeds to PROVIDE THE THREAT SCORE TO THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET TO ENABLE THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET TO SECURE AGAINST THE POTENTIAL SECURITY THREAT OPERATION 319.
In one embodiment, at PROVIDE THE THREAT SCORE TO THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET TO ENABLE THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET TO SECURE AGAINST THE POTENTIAL SECURITY THREAT OPERATION 319, the threat score is provided to the extrusion detection capable virtual asset to enable the extrusion detection capable virtual asset to secure against the potential security threat.
In some embodiments, threat scores associated with suspect messages are provided to the extrusion detection capable virtual assets on a periodic basis in digests, rather than in real time. In some embodiments, threat scores between 0 and 5 are periodically provided to the extrusion detection capable virtual assets, e.g., on a weekly, semi-monthly, or monthly basis. In one embodiment, threat scores of between 8 and 10 are immediately provided to the extrusion detection capable virtual assets. In one embodiment, threat scores are provided to the extrusion detection capable virtual assets according to the computing resources and human resources available.
The threat scores are provided to the extrusion detection capable virtual assets for consideration and/or remedial action, according to one embodiment. In some embodiments, one or more identifiers, e.g., an IP address, involved in the potential security threat are provided to the extrusion detection capable virtual assets to allow the extrusion detection capable virtual assets to block future communications associated with the suspect message.
In one embodiment, the extrusion detection capable virtual asset secures against the potential security threat by submitting the security threat to disciplinary authorities to track down and punish the author(s) of the security threat. In other embodiments, the extrusion detection capable virtual asset secures against the potential security threat by blocking access of one or more computing systems to the extrusion detection capable virtual asset.
In one embodiment, once the threat score is provided to the extrusion detection capable virtual asset at PROVIDE THE THREAT SCORE TO THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET TO ENABLE THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSET TO SECURE AGAINST THE POTENTIAL SECURITY THREAT OPERATION 319, process flow proceeds to FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321.
In one embodiment, the detected suspect messages of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315 are temporarily permitted to be transmitted from the virtual assets through the network communications channel with minimal delay.
In one embodiment, this transmission is permitted in order to avoid significantly disrupting or delaying the transmission of messages without further evidence that the suspect messages are indeed malicious. However, in one embodiment, at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321, for each detected suspect message of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315, suspect message copy data is generated representing a copy of at least part of the message data making up the suspect message.
In one embodiment, for each detected suspect message of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315, the at least part of the message data making up the suspect message is decrypted and decrypted suspect message copy data is generated representing a decrypted copy of at least part of the message data making up the suspect message at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321.
In one embodiment, once for each detected suspect message of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A SUSPECT MESSAGE OPERATION 315, suspect message copy data is generated representing a copy of at least part of the message data making up the suspect message at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321, process flow proceeds to TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323.
In one embodiment, at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323, the suspect message copy data of FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321 is transmitted to one or more analysis systems for further analysis in an “off-line” environment.
In one embodiment, at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323, the suspect message copy data of FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321 is transmitted to the one or more analysis systems via a message analysis channel, also referred to herein as a third communications channel, that is distinct from the network communications channel, i.e., the first communications channel through which messages are transmitted from the virtual assets relayed by the network communications device of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 303. In this way, the transmission of the suspect message copy data, and the subsequent message data analysis, does not affect the operation of the virtual asset, and/or the cloud computing environment, application, service, enterprise, and/or infrastructure associated with the virtual asset.
In one embodiment, multiple analysis systems are provided at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323 that are specifically implemented to analyze specific analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 307.
Consequently, in one embodiment, the particular analysis system to which a given example of suspect message data is transmitted at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323 is determined, at least in part, by the specific analysis trigger parameter detected in the suspect message at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 from which the suspect message copy data was derived at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321.
In one embodiment, if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323, it is determined that the suspect message is indeed associated with an extrusion attack, one or more systems, entities, and/or parties, are alerted to the situation so that appropriate protective action can be taken.
In one embodiment, if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323, it is determined that the suspect message is indeed associated with an extrusion attack, one or more protective actions are automatically taken to prevent further infection of the virtual assets, and/or other virtual assets, and/or the cloud computing environment, application, service, infrastructure, or computing environment, associated with the now identified infected virtual asset.
In various embodiments, the protective actions taken can include, but are not limited to, isolating the virtual asset such that the virtual asset can still continue to operate, but in total isolation of all other virtual assets; partially isolating the virtual asset such that the virtual asset is allowed to connect to some very specific virtual assets, but has most of its communication channels blocked; “killing” or terminating the virtual asset; repairing the virtual asset by re-loading the compromised sub-components of the virtual asset; and/or any other protective actions, or combination of protective actions, discussed herein, and/or as known in the art at the time of filing, and/or as developed, or become known, after the time of filing.
In addition, analysis trigger parameters are applied heuristically at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT FROM EACH OF THE EXTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 313 and if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323, it is determined that the suspect message is indeed associated with an extrusion attack, new analysis trigger parameters that are thereby discovered by the application of process 300 for virtual asset assisted extrusion detection in a cloud computing environment are added to create a self-learning extrusion detection system.
In one embodiment, once the suspect message copy data of FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 321 is transmitted to one or more analysis systems for further analysis in an “off-line” environment at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 323, process flow proceeds to EXIT OPERATION 330.
In one embodiment, at EXIT OPERATION 330 process 300 for virtual asset assisted extrusion detection in a cloud computing environment is exited to await new data.
Using process 300 for virtual asset assisted extrusion detection in a cloud computing environment discussed above, extrusion attacks can be detected using largely existing cloud computing environment infrastructure, such as modified virtual assets with added analysis trigger monitoring systems; without the need for devoting extensive and/or specialized resources. Consequently, using process 300 for virtual asset assisted extrusion detection in a cloud computing environment, extrusion events can be efficiently and effectively detected; thereby making distributed computing environments, such as cloud computing environments, more secure.
In accordance with one embodiment, a process for virtual asset assisted intrusion detection in a cloud computing environment includes providing a cloud computing environment. In one embodiment, the cloud computing environment includes one or more virtual assets. In one embodiment, one or more of the one or more virtual assets in the cloud computing environment is provided an analysis trigger monitoring system; thereby transforming the one or more virtual assets in the cloud computing environment provided an analysis trigger monitoring system into intrusion detection capable virtual assets for the cloud computing environment. In one embodiment, one or more analysis trigger parameters are defined and analysis trigger data representing the analysis trigger parameters is generated. In one embodiment, the analysis trigger data is provided to the analysis trigger monitoring systems of the intrusion detection capable virtual assets. The analysis trigger monitoring systems and the analysis trigger data are then used to monitor at least a portion of the message traffic sent to the virtual assets in the cloud computing environment to detect any message including one or more of the one or more analysis trigger parameters.
In one embodiment, any detected message including one or more of the one or more analysis trigger parameters is identified as a suspect message and, for each suspect message, suspect message copy data representing a copy of at least a portion of the suspect message is generated. In one embodiment, the suspect message copy data is then transferred to one or more analysis systems for further analysis.
FIG. 4 is a flow chart of a process 400 for virtual asset assisted intrusion detection in a cloud computing environment in accordance with one embodiment. In one embodiment, process 400 for virtual asset assisted intrusion detection in a cloud computing environment begins at ENTER OPERATION 401 of FIG. 4 and process flow proceeds to PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403.
In one embodiment, at PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 a cloud computing environment is provided.
In various embodiments, the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 can be any form of cloud computing environment, such as, but not limited to, a Virtual Private Cloud, or VPC.
In many cases, a given application or service provided through a cloud computing infrastructure may utilize, and interface with, multiple cloud computing environments, including multiple VPCs, in the course of providing the associated service. As noted above, each cloud computing environment includes allocated virtual assets associated with, and controlled or used by, the party utilizing the cloud computing environment.
As used herein, the term “virtual asset” includes any virtualized entity or resource, and/or part of an actual, or “bare metal” entity requiring access to various resources, and types of resources. In various embodiments, the virtual assets can be, but are not limited to, virtual machines, virtual servers, and instances implemented in a cloud computing environment; databases implemented, or associated with, a cloud computing environment, and/or instances implemented in a cloud computing environment; services associated with, and/or delivered through, a cloud computing environment; communications systems used with, part of, or provided through, a cloud computing environment; and/or any other virtualized assets and/or sub-systems of “bare metal” physical devices such as mobile devices, remote sensors, laptops, desktops, point-of-sale devices, ATMs, electronic voting machines, etc. requiring access to various resources, and/or types of resources, located within a data center, within a cloud computing environment, and/or any other physical or logical location, as discussed herein, and/or as known/available in the art at the time of filing, and/or as developed/made available after the time of filing.
In one embodiment, virtual asset creation data is generated through a virtual asset creation system such as a virtual asset template through which the creator of a virtual asset can generate operational logic and assign resources and attributes to the virtual assets to be instantiated in a cloud computing environment, such as a virtual private cloud computing environment.
In one embodiment, once a cloud computing environment is provided at PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403, process flow proceeds to PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405.
In one embodiment, at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 a network communications device is provided for each cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403.
In various embodiments, the network communications devices of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 provided for the cloud computing environments of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 include, but are not limited to, one or more of a switching system, such as a network switch; a router; a border router; any gateway system; a firewall system; a load balancing system; a hypervisor; or any communication, relay, or routing system, as discussed herein, and/or as known in the art at the time of filing, and/or as developed after the time of filing, through which message traffic on a network communications channel to, or from, an external network, such as the Internet, is relayed, and/or routed, to one or more virtual assets in a cloud computing environment.
In one embodiment, incoming message traffic sent to one or more of the virtual assets associated with a given cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 from an origin external to the cloud computing environment, such as the Internet, is relayed through the network communications device for that cloud computing environment of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405.
In one embodiment, the incoming message traffic is relayed through the network communications device of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 via at least one communications channel, e.g., a network communications channel, herein also referred to as a first communications channel.
As noted above, in various embodiments, the incoming message traffic from the virtual assets associated with a given cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 are susceptible to the introduction of malware and, in particular, intrusion related malware.
As also noted above, the fact that malware can be introduced into the cloud computing environments of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 is a long standing problem. Consequently, the detection of malware intrusion is an important part of making the cloud computing environments of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 more secure. However, as also noted above, a given cloud computing environment, and/or virtual private cloud computing environment, can include hundreds, thousands, or even millions, of virtual assets, owned or used by hundreds, thousands, or even millions, of parties. Consequently, detecting malware intrusion in a cloud computing environment is currently an extremely difficult and resource intensive task.
To address this issue, in one embodiment, at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 one or more virtual assets within, and/or assigned to, the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 are provided an analysis trigger monitoring system.
In one embodiment, by virtue of the addition of the analysis trigger monitoring system logic to one or more of the one or more virtual assets in the cloud computing environment at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 the one or more virtual assets in the cloud computing environment provided an analysis trigger monitoring system are transformed into intrusion detection capable virtual assets for the cloud computing environment.
In various embodiments, the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 is a module of software and/or logic implemented in, or on, the one or more virtual assets and capable of monitoring at least a portion of the message traffic to one or more virtual assets instantiated in the cloud computing environment.
In various embodiments, process 400 for virtual asset assisted intrusion detection in a cloud computing environment is applied to network communications, e.g., message traffic, which is in plain text or is encrypted. Consequently, in some embodiments, the analysis trigger monitoring system, and/or the network communications device, and/or the intrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 include a decryption capability to decrypt incoming message traffic as part of the monitoring and analysis. In other embodiments, a decryption capability is provided to decrypt incoming message traffic prior to being provided to analysis trigger monitoring system and any monitoring and analysis.
As discussed below, in some embodiments, the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 allows for analysis policies to be added, or removed, dynamically based on alerts that are received.
In one embodiment, once one or more virtual assets within, and/or assigned to, the cloud computing environment of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403 are provided an analysis trigger monitoring system at PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405, process flow proceeds to DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 407.
In one embodiment, at DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 407 one or more analysis trigger parameters are defined such that if one or more of the one or more analysis trigger parameters are detected in a message to a virtual asset, then that message is deemed a suspect message that is potentially associated with an intrusion attack on the virtual asset, and/or the cloud computing environment. In one embodiment, an analysis trigger parameter can be found in the procedural characteristics of message traffic and/or can be found in the content of message traffic. Procedural characteristics of the message traffic include, but are not limited to, frequency, time of day, and/or the lapses between transmissions of commands, data, and requests associated with application programming interfaces (“APIs”) or other interfaces, for example, between computing systems, according to one embodiment. Table 1 is provided below with an example threat pattern that can be used as an analysis trigger.

As seen above, Table 1 includes an API column, a normal traffic pattern column, and a suspicious traffic pattern column. The online service API column illustrates an order in which example APIs are called or executed during an example routine request. In Table 1, the order by which the example APIs should be called is: “API A”, “API B”, “API A”, “API C”, “API D”, and “API E”, as an example. Some APIs can return significantly more information and parameters than other APIs, so some APIs may require a longer duration of processing prior to execution of a subsequent API. For example, API A may return smaller quantities of information and/or small sized files in response to execution. In contrast, API B, API D, and API E, may return large files and/or large numbers of parameters that need processing prior to execution of a subsequent API. For APIs that return large amounts of information, minimum execution times may be noted that a well-equipped computing system would be unable to out-perform. Processing times may then be used as flags, or trigger parameters, that are faster than the minimum time limitations as suspicious. Therefore, a normal traffic pattern for the online service APIs of Table 1 is “FAST”, “SLOW”, “FAST”, “FAST”, “SLOW”, and “SLOW”, according to one embodiment. A suspicious traffic pattern for the order of the online service APIs of Table 1 is “FAST”, “FAST”, “FAST”, “SLOW”, “FAST”, and “SLOW”, according to one embodiment. The suspicious traffic pattern is suspicious when compared to the normal traffic pattern at least because API B and API D are executed more rapidly than should be possible with premium computing resources, according to one embodiment. In another embodiment, the suspicious traffic pattern is suspicious when compared to a normal traffic pattern because of an ordering of API executions that does not make sense. For example, if an API is dependent on one or more other APIs but is executed prior to the APIs upon which it is dependent, such API executions may be identified as suspicious.

In one embodiment, once at least part of the analysis trigger data of GENERATE ANALYSIS TRIGGER DATA REPRESENTING THE ANALYSIS TRIGGER PARAMETERS OPERATION 409 is provided to the analysis trigger monitoring systems of PROVIDE A NETWORK COMMUNICATIONS DEVICE FOR RELAYING MESSAGE TRAFFIC SENT TO EACH OF THE VIRTUAL ASSETS OPERATION 405 at PROVIDE THE ANALYSIS TRIGGER DATA TO THE ANALYSIS TRIGGER MONITORING SYSTEMS OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 411, process flow proceeds to USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413.

In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413 a sample part of the message data associated with at least some of the message traffic to at least some of the intrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413 all of the message data to at least some of the intrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413 at least part of the message data from all of the intrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413 all of the message data associated with all of the intrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 is monitored to detect one or more of the one or more analysis trigger parameters within the message data.
In one embodiment, the analysis of USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413 is performed by the analysis trigger monitoring systems in-line, or asynchronously off-line, on a per-message basis. Consequently, in some embodiments, an initial or first example of an intrusion message is passed through a given intrusion detection capable virtual asset but would be used to stop other “like messages” where the criteria for “like” is an analysis trigger parameter that can be dynamically installed in the trigger monitoring system.
In addition, in one embodiment, analysis trigger parameters are applied heuristically at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413 and new analysis trigger parameters that are discovered by the application of process 400 for virtual asset assisted intrusion detection in a cloud computing environment are added to create a self-learning intrusion detection system.
In one embodiment, once the analysis trigger data of GENERATE ANALYSIS TRIGGER DATA REPRESENTING THE ANALYSIS TRIGGER PARAMETERS OPERATION 409 and the analysis trigger monitoring system of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 are used to monitor at least part of the message data associated with at least some of the intrusion detection capable virtual assets of PROVIDE ONE OR MORE OF THE VIRTUAL ASSETS AN ANALYSIS TRIGGER MONITORING SYSTEM TO TRANSFORM THE ONE OR MORE VIRTUAL ASSETS INTO INTRUSION DETECTION CAPABLE VIRTUAL ASSETS OPERATION 405 at USE THE ANALYSIS TRIGGER MONITORING SYSTEMS AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE INTRUSION DETECTION CAPABLE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS OPERATION 413, process flow proceeds to CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415.
In one embodiment, at CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415, if one or more of the one or more analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 407 is detected within the message data associated with a given message, the classification data associated with that message is transformed into classification data indicating that the detected message including one or more of the one or more analysis trigger parameters is a suspect message.
In one embodiment, once the classification data associated with messages having one or more of the one or more analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 407 is transformed into classification data indicating that the detected message including one or more of the one or more analysis trigger parameters is a suspect message at CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415, process flow proceeds to ASSIGN A THREAT SCORE TO THE SUSPECT MESSAGE AT LEAST PARTIALLY BASED ON A POTENTIAL IMPACT OF THE SUSPECT MESSAGE'S POTENTIAL SECURITY THREAT ON THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET OPERATION 417.
In one embodiment, at ASSIGN A THREAT SCORE TO THE SUSPECT MESSAGE AT LEAST PARTIALLY BASED ON A POTENTIAL IMPACT OF THE SUSPECT MESSAGE'S POTENTIAL SECURITY THREAT ON THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET OPERATION 417, a threat score is assigned to the suspect message based, at least partially, on a potential impact of the suspect message's potential security threat on the intrusion detection capable virtual asset.
For example, if the potential security threat can compromise financial data, e.g., credit card information of users, the threat score will be higher than if the potential security threats cause minor decreases in network connectivity speeds, according to one embodiment. To determine the potential impact of the potential security threat, the process evaluates the context of the potential security threat. In other words, the process evaluates the characteristics of the intrusion detection capable virtual asset, the type of threat, the likelihood of success of the threat, and the like.
In one embodiment, a threat score is assigned to a suspect message based on the relative impact of a potential security threat to the intrusion detection capable virtual asset. For example, based on the impact of the potential security threat, a numerical threat score can be assigned to the suspect message. For example, a threat score of 10 can be assigned to suspect messages having potential security threats with the highest probability of successful attack and that acquire personal data of users of the intrusion detection capable virtual asset. A 0 (zero) can be assigned to suspect messages having potential security threats with the lowest probability of successful attack and/or that are likely to have a negligible effect on the performance of the intrusion detection capable virtual asset, according to one embodiment. Various factors, such as asset configuration, number of subscribers, security features developed into the intrusion detection capable virtual asset, notification of new security threats or external risks, or input from a third party vulnerability scanner, can provide context while assessing a potential security threat and assigning a threat score. In some embodiments, the threat scores range between 0-10. In other embodiments, the threat scores range between 0 and 100. In yet other embodiments, the threat scores include values, such as, “LOW,” “MEDIUM,” and “HIGH.” In one embodiment, the threat scores can include color coordinating so that high priority potential security threats are red, low priority potential security threats are orange, and the absence of potential security threats is indicated with green. As those of skill in the art will appreciate, other scoring ranges or values can be used while assigning a threat score to a suspect message having a potential security threat, according to various embodiments.
In one embodiment, once a threat score is assigned to the suspect message at ASSIGN A THREAT SCORE TO THE SUSPECT MESSAGE AT LEAST PARTIALLY BASED ON A POTENTIAL IMPACT OF THE SUSPECT MESSAGE'S POTENTIAL SECURITY THREAT ON THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET OPERATION 417, process flow proceeds to PROVIDE THE THREAT SCORE TO THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET TO ENABLE THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET TO SECURE AGAINST THE POTENTIAL SECURITY THREAT OPERATION 419.
In one embodiment, at PROVIDE THE THREAT SCORE TO THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET TO ENABLE THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET TO SECURE AGAINST THE POTENTIAL SECURITY THREAT OPERATION 419, the threat score is provided to the intrusion detection capable virtual asset to enable the intrusion detection capable virtual asset to secure against the potential security threat.
In some embodiments, threat scores associated with suspect messages are provided to the intrusion detection capable virtual assets on a periodic basis in digests, rather than in real time. In some embodiments, threat scores between 0 and 5 are periodically provided to the intrusion detection capable virtual assets, e.g., on a weekly, semi-monthly, or monthly basis. In one embodiment, higher threat scores, e.g. threat scores of between 8 and 10, for example, are immediately provided to the intrusion detection capable virtual assets. In one embodiment, threat scores are provided to the intrusion detection capable virtual assets according to the computing resources and human resources available.
The threat scores are provided to the intrusion detection capable virtual assets for consideration and/or remedial action, according to one embodiment. In some embodiments, one or more identifiers, e.g., an IP address, involved in the potential security threat are provided to the intrusion detection capable virtual assets to allow the intrusion detection capable virtual assets to block future communications associated with the suspect message.
In one embodiment, the intrusion detection capable virtual asset secures against the potential security threat by submitting the security threat to disciplinary authorities to track down and punish the author(s) of the security threat. In other embodiments, the intrusion detection capable virtual asset secures against the potential security threat by blocking access of one or more computing systems to the intrusion detection capable virtual asset.
In one embodiment, once the threat score is provided to the intrusion detection capable virtual asset at PROVIDE THE THREAT SCORE TO THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET TO ENABLE THE INTRUSION DETECTION CAPABLE VIRTUAL ASSET TO SECURE AGAINST THE POTENTIAL SECURITY THREAT OPERATION 419, process flow proceeds to FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421.
In one embodiment, the detected suspect messages of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415 are temporarily permitted to be transmitted to the virtual assets through the network communications channel with minimal delay.
In one embodiment, this transmission is permitted in order to avoid significantly disrupting or delaying the transmission of messages without further evidence that the suspect messages are indeed malicious. However, in one embodiment, at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421, for each detected suspect message of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415, suspect message copy data is generated representing a copy of at least part of the message data making up the suspect message.
In one embodiment, for each detected suspect message of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415, the at least part of the message data making up the suspect message is decrypted and decrypted suspect message copy data is generated representing a decrypted copy of at least part of the message data making up the suspect message at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421.
In one embodiment, once suspect message copy data is generated representing a copy of at least part of the message data making up the suspect message at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421 for each detected suspect message of CLASSIFY ANY DETECTED MESSAGE INCLUDING ONE OR MORE OF THE ANALYSIS TRIGGER PARAMETERS AS A POTENTIAL SECURITY THREAT OPERATION 415, process flow proceeds to TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423.
In one embodiment, at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423, the suspect message copy data of FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421 is transmitted to one or more analysis systems for further analysis in an “off-line” environment.
In one embodiment, at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423, the suspect message copy data of FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421 is transmitted to the one or more analysis systems via a message analysis channel, also referred to herein as a third communications channel, that is distinct from the network communications channel, i.e., the first communications channel through which messages are transmitted from the virtual assets relayed by the network communications device of PROVIDE A CLOUD COMPUTING ENVIRONMENT INCLUDING ONE OR MORE VIRTUAL ASSETS OPERATION 403. In this way, the transmission of the suspect message copy data, and the subsequent message data analysis, does not affect the operation of the virtual asset, and/or the cloud computing environment, application, service, enterprise, and/or infrastructure associated with the virtual asset.
In one embodiment, multiple analysis systems are provided at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423 that are specifically implemented to analyze specific analysis trigger parameters of DEFINE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 407.
Consequently, in one embodiment, the particular analysis system to which a given example of suspect message data is transmitted at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423 is determined, at least in part, by the specific analysis trigger parameter detected in the suspect message at USE THE ANALYSIS TRIGGER MONITORING SYSTEM AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE ONE OR MORE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 413 from which the suspect message copy data was derived at FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421.
In one embodiment, if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423, it is determined that the suspect message is indeed associated with an intrusion attack, one or more systems, entities, and/or parties, are alerted to the situation so that appropriate protective action can be taken.
In one embodiment, if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423, it is determined that the suspect message is indeed associated with an intrusion attack, one or more protective actions are automatically taken to prevent further infection of the virtual assets, and/or other virtual assets, and/or the cloud computing environment, application, service, infrastructure, or computing environment, associated with the now identified infected virtual asset.
In various embodiments, the protective actions taken can include, but are not limited to, isolating the virtual asset such that the virtual asset can still continue to operate, but in total isolation of all other virtual assets; partially isolating the virtual asset such that the virtual asset is allowed to connect to some very specific virtual assets, but has most of its communication channels blocked; “killing” or terminating the virtual asset; repairing the virtual asset by re-loading the compromised sub-components of the virtual asset; and/or any other protective actions, or combination of protective actions, discussed herein, and/or as known in the art at the time of filing, and/or as developed, or become known, after the time of filing.
In addition, in one embodiment, analysis trigger parameters are applied heuristically at USE THE ANALYSIS TRIGGER MONITORING SYSTEM AND THE ANALYSIS TRIGGER DATA TO MONITOR AT LEAST A PORTION OF THE MESSAGE TRAFFIC SENT TO EACH OF THE ONE OR MORE VIRTUAL ASSETS TO DETECT ANY MESSAGE INCLUDING ONE OR MORE OF THE ONE OR MORE ANALYSIS TRIGGER PARAMETERS OPERATION 413 and if, as a result of the analysis of the suspect message copy data by one or more of the analysis systems at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423, it is determined that the suspect message is indeed associated with an intrusion attack, new analysis trigger parameters that are thereby discovered by the application of process 400 for virtual asset assisted intrusion detection in a cloud computing environment are added at to create a self-learning intrusion detection system.
In one embodiment, once the suspect message copy data of FOR EACH SUSPECT MESSAGE GENERATE SUSPECT MESSAGE COPY DATA REPRESENTING A COPY OF AT LEAST A PORTION OF THE SUSPECT MESSAGE OPERATION 421 is transmitted to one or more analysis systems for further analysis in an “off-line” environment at TRANSFER THE SUSPECT MESSAGE COPY DATA TO ONE OR MORE ANALYSIS SYSTEMS FOR FURTHER ANALYSIS OPERATION 423, process flow proceeds to EXIT OPERATION 430.
In one embodiment, at EXIT OPERATION 430 process 400 for virtual asset assisted intrusion detection in a cloud computing environment is exited to await new data.
Using process 400 for virtual asset assisted intrusion detection in a cloud computing environment discussed above, intrusion attacks can be detected using largely existing cloud computing environment infrastructure, such as modified virtual assets with added analysis trigger monitoring systems; without the need for devoting extensive and/or specialized resources. Consequently, using process 400 for virtual asset assisted intrusion detection in a cloud computing environment, intrusion events can be efficiently and effectively detected; thereby making distributed computing environments, such as cloud computing environments, more secure.
