     FIELD OF THE INVENTION 
       [0002]    The present invention generally relates to network security and in particular to an automated system and method for detecting, evaluating and reporting network threats. 
       BACKGROUND 
       [0003]    The threat landscape has grown exponentially since the early 2000&#39;s, along with this landscape technology has continued to outpace itself, data has continued to grow, and the qualified people with the skillsets to sift through this data has shrunk. Computer security has become one of the largest markets in the technology field. It is becoming quintessential to everyday business, protection of intellectual property and to organizations, a way to stabilize the ever growing cyber arms race faced by nation states surrounding the economic empires of Americas, European, Russian, and Asia. 
         [0004]    By way of example, there is a lack of ability and need to present security data to two major consumers of this type or category of data including analysts and customers. In current threat landscape, traditional portals that support security analysis or a customer base do not provide the comprehensive approach that is needed with the amount of data that is typically required to be presented in order for decisions to be made quickly, made by the right people, and made for the right reasons. These “security portals” typically do not have this comprehensive approach reflected to the customer in an easily readable, graphics intensive illustration that shows real-time threat data, the root cause analysis, metrics based on analysts assigned to monitor and security company assets, and the vulnerabilities associated with those assets. 
       SUMMARY 
       [0005]    Embodiments of the present invention, including systems and methods, serve to increate automation, analysis, and reporting of analysis to customers through several functions, programs. Systems and methods according to the teachings of the present invention provide advancements in areas that traditional security reporting and operations portals do not provide. 
         [0006]    Embodiments of the invention may provide Real-Time Labeling, Sorting, Ranking of Incidents, by way of example. One embodiment may comprise a threat intelligence product that feeds portal real-time incident information providing situation awareness of sorted, categorized/labeled and ranked for our analysts. 
         [0007]    Metrics and Routing of Incident Information may be provided. By way of example. a threat intelligence system may include analyst profiles stored which have inputs about analyst capabilities, background, and the like, that allow intelligent decision making by an incident routing system so that incidents that arrive at an analyst&#39;s desk match not only a skill level, but familiarity with customer assets affected by the incident. 
         [0008]    Pivoting to Security Devices may be provided. By way of example, a threat intelligence system may comprise built-in links and direct software calls to various brands of security devices that are presented to the analyst so that a simple “click” will allow them to “pivot” into security devices to investigate incidents alerted to them by our threat intelligence programs. 
         [0009]    Common Analysis Processes may be provided. By way of example, a threat intelligence system may allow triage of alerted incidents through simultaneous editing and work flow on incidents with real-time chat, spell checking, customer checks to make sure tickets are for the customer intended, and war-room response to involve a full suite of analysis by using contextual searches on previous written tickets. 
         [0010]    Believability and Reliability may be provided. By way of example, a system may include functionality that takes input from the analyst that is sent to a threat intelligence program in order to help with believability and reliability rankings of the incident alerts that our analysts see. 
         [0011]    Scenario Based Ticket Creation may be provided. A system may provide an input form with various menus that allow an analyst to build an illustrated incident scenario such as type of attack, type of asset, time based analysis, and transaction base analysis that provides overview through graphical entity illustrations to the client. 
         [0012]    Customizable Views may be provided. By way of example, a system may provide a module-based, customized view in which customers have over 30 different types of data views that can be displayed from parabolic graphics, 3D views of geo-locations, etc. 
         [0013]    Link Analysis may be provided, wherein a system provides a robust illustration of incidents that characterize incidents in terms of entities, relationship based computer to computer transactions based on data flow analysis, exploit used, success rate, compromise rate, and ranking of the data stream used in the incident, by way of example. 
         [0014]    Root Cause Analysis may be provided. By way of example, a system may provide insight into the root cause of the incident that was reported. The incident may be categorized based on analyzing the timeline and/or sequence of events, confirmation of an exploit and or attempted exploit of the computer system, and human analysis of the event. 
         [0015]    Vulnerability Data Association may be provided. By way of example, a system may provide an interface and logical mapping of enterprise IT assets across incidents, ranking those assets per a level of criticality to business units and or business objectives of the customer. Vulnerability data may be paired with asset information and incident information in order to provide the customer with a holistic view of their security posture. 
         [0016]    Asset Management may be provided. By way of example, a system may provide an ability to receive in different file formats, and/or export from leading IT Asset Products the asset lists for customer enterprise computer systems and infrastructure, so that assets are linked to the computer systems that are described in the incident that is being reported to the customer. 
         [0017]    Metrics may be provided, wherein by way of example, a system is enriched with a program that drives calculations of metrics on the analyst&#39;s over a period of time, allowing customers to be served by not only the correct analyst for their business vertical, but serve to allow the customer insight into threat intelligence operations by systems and methods of the invention, and the talent that serves a contract between a provider of embodiments of the invention and the customer. 
         [0018]    One method aspect of the invention may include a computer-implemented method for detecting and reporting an internet threat. The method may comprise collecting a plurality of cyber threat data for an incident from a plurality of threat intelligence sources; weighting the cyber threat data based on past performance by the threat intelligence source providing the data; sorting the cyber threat data by severity and reliability for providing indicators for the incident; connecting to a client system; monitoring incidents of the cyber threats on the client system; retrieving incidents detected on the client system; selecting at least one incident by an analyst; displaying known information about the at least one incident to the analyst; analyzing the incident by the analyst based on the indicators of the cyber threat data; transmitting an incident report to the client system by the analyst, wherein the incident report includes a recommended course of action and modification to the user system; closing the incident report; and updating a database with the closed incident report. 
         [0019]    It will be understood by those of ordinary skill in the art that where reference is made to a system, an appropriate related method is applicable and supported by the present disclosure.

     DETAILED DESCRIPTION OF EMBODIMENTS 
       [0029]    The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which embodiments of the invention are shown by way of illustration and example. This invention may, however, be embodied in many forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. 
         [0030]    With reference initially to  FIG. 1 , one system and associated method according to the teachings of the present invention is herein described, by way of example, as comprising two large components that fall in the category of data display components, which are aptly named Analyst and Customer. These two data display functions are both supported by two components named client side and server side. 
         [0031]    The client side is a set of procedural steps taken in the lifecycle of one incident report. A connection to the server is opened. A list of incidents is retrieved and displayed. An analyst selects an incident and all known information is displayed to the analyst. After an incident is claimed, reporting fields are displayed for customer and internal reporting made. When reporting has finished, the analyst closes the incident and the database is updated with the closed report. 
         [0032]    With continued reference to  FIG. 1 , the server side is an event driven and input driven process in which delivers client-side requested information about the incidents. After receiving the request to open a connection to the client, the server retrieves a list of incidents from the incident database and passes it to the client. Additional information is made available to the client for all incidents passed in the list. Further, the client has multiple features available as illustrated with reference to  FIG. 3 . When an incident is claimed, it is updated in the database and all clients are informed of the claim. Reports are stored in the database as the client makes fills them out, and when the report is marked as complete in the database, and all clients are informed of the update. 
         [0033]    The first component that makes up the client side program is called, “Establish Connection.” After authenticating, a socket connection is established with the server. Data are then synced across client and server. Once all necessary items are set to sync and other objects used only by the client are instantiated, the client requests the list of incidents from the server. 
         [0034]    After connecting to the server, the client receives the list of incidents as an array of objects. Each item in the list represents one incident with several key fields meant to help an analyst quickly differentiate one incident from another. Each incident is parsed into an HTML list item and table row, given a class to help differentiate open incidents from claimed ones, and a click event handler is attached to each one. The list of incidents is then animated into the document for the analyst to interact with. When an incident is clicked, the client requests all additional information about the incident from the server. 
         [0035]    In a claim incident, the data from the server-side are returned as a dictionary of key value pairs. Each pair represents one field and its respective value about the incident. The pairs are parsed into table cells and displayed on the screen. If the incident had already been claimed by another analyst, no other options are made available beyond viewing the information about the incident as well as which analyst is handling it. If an analyst has not already claimed the incident, a claim button is made visible. Clicking the button sends the claim command to the server. The client then reinterprets the incident as being claimed by the analyst. When the incident is marked as claimed by the analyst, the reporting process becomes available. 
         [0036]    After claim incident process flow has finished, the reporting process becomes available to the analyst. Once the reporting process is available, two fields are displayed, one for a client report, and one for internal reporting. Key press event handlers are attached to each field that sends a command to the server to save the modified report. A close report button is also made visible which when clicked will send a command to the server closing the completed report. After receiving confirmation from the server, the view is reset and the updated incident list is requested again. A close report functional flow is illustrated with referee again to  FIG. 3 . 
         [0037]    As herein described by way of example for one embodiment, there are two ways that the incident is sorted either by a client-defined filter and or the list is sorted comparing severity, believability, and the time the incident was discovered. The list is then parsed into a browser-friendly format and sent back to the client for display. When the client requests additional information about an incident, all information known about the incident is retrieved from the database, parsed, and sent back to the client for display. Upon receiving the command to mark an incident as claimed, the record is updated in the database, and the incident is no longer available to other clients for claiming. The reporting fields associated with the incident are unlocked and the server sends the client the signal to allow reporting. As the report is filled out on the client side, all changes are sent to the server to be stored to allow multitasking by the analyst. If the incident information is requested again later, the reports are sent along with it to allow analysts to work on multiple incidents at once while preventing data loss. When the client sends the command to close the report, the record is marked as closed and is removed from display. The record is no longer available in the standard filter and must be specially requested by an analyst to view any closed report. 
         [0038]    Customizable Views are available. By way of example and with reference to  FIG. 4 , a Customizable Dashboard meant to display metrics, statistics, and live insight into a customer&#39;s network. Information is displayed through dynamic widgets that can be moved, resized, removed, or added as the customer sees fit, with a persistent layout that is stored for each user via a profile. The widgets serve as an easy entry point for drilldown on incidents; threat Intel, assets, analysts, etc. 
         [0039]    Link Analysis is available. Data from analyst reports and information provided by automated analytics is processed, producing a graph showing the links between incidents and other events in the customer&#39;s network. Information is displayed as an interactive web, allowing for customer drilldown into the individual events to better analyze the incident. 
         [0040]    Further, systems and methods according to the teachings of the present invention provide Root Cause Analysis, Vulnerability Data Association, and Asset Management. The system provides insight into the root cause of the incident that was reported. When the forms are generated for the asset, that asset is assigned a category and associated with vulnerability information input previously by a customer. An analyst that examines the timeline then categorizes the incident or sequences of events, confirmation of exploit or attempted exploit. 
         [0041]    An interface that allows the customer to import vulnerability data into the customer portal that is stored in the incident database, tied to asset management. When an incident affects a certain asset, the display page shows a logical mapping of assets across incidents, ranking those per level of criticality. Analysts are then routed via the server side this information per the metrics and routing functionality. A page is dedicated to allowing the customer to manually add asset information regarding types of devices, and associating priority with each respective device. By providing this information, the customer helps tailor the automated response, affecting how incidents are displayed to an analyst by differentiating critical systems from normal devices. 
         [0042]    As analysts operate on incidents identified in the customer&#39;s environment, statistics are tracked and displayed to the customer. Information like most severe incidents identified, number of false positives, average incidents per day, asset with most number of incidents, etc. are all available, and all act as starting points for drilldown. 
         [0043]    Embodiments of the system are built in module sections of code client side and server side, which support the architecture of both system analyst dashboard and customer dashboard. By way of non-limiting example only, the tickets and analyst part is known as analyst and the customer dashboard is known as customer. 
         [0044]    In order to provide the efficient sharing of data between analysts and the threat intelligence engine in a security operations center, reference is again made to  FIG. 3 . As illustrated in  FIG. 3  for retrieving an incident list, a specific process flows where information presented to the analysts is controlled by two factors such as client-driven filter profiles about the analyst and the threat intelligence alert which is sorted by performing machine learning and human analysis on comparing the severity, believability, reliability and timing of incident discovery. These factors are weighted to perform averages over determinate periods of time increasing the intelligence about the speed with which we provide our analysts with the latest incident based on threat intelligence feeds and automated direct code access to enterprise security devices. The objective of Incident List retrieval functionality is to provide real-time, near instant streaming of incidents to our analysts that are ranked in order to provide prioritization through criticality, asset, vulnerability, root-cause, and the like. 
         [0045]    The system provides advanced metrics and routing of incident information. Referring again to  FIG. 3 , block entitled “Send Client Incident Information” under the retrieve incident information process flow, is where the portal has profiles stored of SOC analysts, measured by key words, years of experience, familiarity with tools, understanding of customer network and assets, etc. The server side engine to makes efficient routing changes and collects metrics on analysts so that incidents match not only skill level but also various other degrees of experience in different categories uses these profiles. 
         [0046]    While improving efficiency of data analysis, sharing of data, routing of incidents is important and also builds contextual information based on what enterprise device detected the incident and or threat that should be presented to the analyst to triage. In order to provide efficiency and speed to investigative analysis in security operation centers, the portal provides direct links to the enterprise security devices in the box called “Send Client Incident List” that allows analysts to pivot directly to information that is more detailed than the alert, this allows for what is termed as deep analysis. 
         [0047]    Automating common analysis processes on the analyst side of the system is desirable for improving analyst processes. Referring again to  FIG. 1 , a process flow is illustrated with reference to the client incident flow for how analysts claim incidents from the client side program. This process flow parses the incident information, presents this to an analyst, which in return opens a flexible web  2 . 0  based chat session to similar ranked analysts allowing for editing and collaboration across ticket portals. In this routine are various checks to make sure the incident is assigned correctly, given the right priority, that spell check and customer are correct and also provides an administrative review option for junior analysts to senior analysts. 
         [0048]    In order to provide an avenue for machine learning algorithms to improve processes, the system utilizes a believability and reliability ranking engine that helps to tailor the incident information the is processed and presented the analyst. Parts of this functionality are illustrated with reference again to  FIG. 3  where all “incident fields” are retrieved as the threat intelligence engine has informed the incident database of previous ranking of believability, and reliability. With reference again to  FIG. 3  regarding an update report function, the analyst can provide human based input to teach the machine learning algorithm of whether the incident was a false positive, the threat intelligence was not correct, and or the threat has since moved and the threat intelligence data needs to be retired because its finite life period has expired, and the information was not used by threat actors recently, etc. 
         [0049]    In order to add in the customer dashboard creation, and the illustration of complex incidents the system also utilizes cutting edge techniques to allow human analysis to illustrate the scenario that correctly describes the incident routed to the analyst. With reference again to  FIG. 1 , referencing an analyst reporting, there are a multitude of drop down menus with entities, attack types, scenario language that is used to build from a form based input the entire attack scenario of the incident going as granular as known malware families and or threat actors that are being tracked by the operations centers that attack certain customer bases. 
         [0050]    Displaying incident information to clients in an intelligent, comprehensive, collated, efficient, and illustrative way that combines power of root-cause, link analysis, vulnerability and asset information is ever more important, to give clients and users the insight into their defensive posture is something that larger, branded, and outdated web portals have tried to do. 
         [0051]    The system starts the display engine with a series of graphical widgets that are event driven consoles, which originate from various data sources. Referring to  FIG. 5 , there are a series of plug and play modules that draw from data points associated within the incident database, analyst inputs and raw intelligence which provide customizable view points and or mini dashboards such as link analysis in the form of parabolic graphs, geo-location view points, threat intelligence highlighted view points, etc. These modules are not selected all at once by the customer view point but are rather a menu of options that allow over 75 different customizations for preparation of data fed from incident ticketing, analysis, human analysis, threat intelligence, open source intelligence gathering, and “darknet” searching providing trademark, company, brand protection trends as related to OSIM (open source intelligence methodology) employed by analysts and automated resources. 
         [0052]    The system also provides a cutting edge presentation layer built around link analysis theory. Reference again to  FIG. 5  illustrates that the data points from an incident, all entities involved are given graphical characters, events are put in a sequence that allow full visual playback for the incident. These data links are graphical characters that hold menu links allowing further drilldown by said customer into computer specific log files, screen captures, analyst notes. 
         [0053]    The system stores large amounts of what is termed “surrounding data”, surrounding data is data about an organizations enterprise including assets, network names, host names, vulnerability data associated with the assets.  FIG. 6  illustrates the asset management functionality of the system, in which surrounding data is organized and associated to assets in order to provide the drill down features of link analysis in  FIG. 5 . The system has a flexible parsing engine allowing upload of asset lists in industry standard formats and populates this into the incident database. Vulnerability data about particular assets are linked directly to those assets in the incident database. Presentation of this data is a sub-routine handled by link analysis in  FIG. 5  where the “surrounding data” is retrieved. The system takes analyst input, illustrated with reference again to  FIG. 1 , which allows analysts to report on a root cause of the incident. This root cause is associated with the vulnerability data inside the incident database adding to the “surrounding data” collected and or inputted into the system. 
         [0054]    In order to gather metrics on large teams of analysts, the system includes a metrics engine in  FIG. 7  titled “Calculate requested metrics across all sets of records”. This calculation allows large teams of analysts to be ranked on various attributes from close of incidents, what type of incidents handled over period of time, level of incident handled on daily or weekly basis.  FIG. 7  allows for collection of metrics that help feed the decision-making processes involved in the routing engine referred to in  FIG. 3 . 
         [0055]    By way of further example and with reference to  FIG. 8 , one method aspect of the invention may include a computer-implemented method for detecting and reporting an internet threat. The method may comprise collecting a plurality of cyber threat data for an incident from a plurality of threat intelligence sources; weighting the cyber threat data based on past performance by the threat intelligence source providing the data; sorting the cyber threat data by severity and reliability for providing indicators for the incident; connecting to a client system; monitoring incidents of the cyber threats on the client system; retrieving incidents detected on the client system; selecting at least one incident by an analyst; displaying known information about the at least one incident to the analyst; analyzing the incident by the analyst based on the indicators of the cyber threat data; transmitting an incident report to the client system by the analyst, wherein the incident report includes a recommended course of action and modification to the user system; closing the incident report; and updating a database with the closed incident report.
