## Title
Systems and methods for detecting data leaks

## Abstract

A computer-implemented method for detecting data leaks may include (1) monitoring at least one data-distribution channel utilized by an entity, (2) detecting a plurality of full DLP policy violations and/or partial DLP policy violations committed by the entity by analyzing data distributed by the entity via the data-distribution channel, (3) determining that the entity's DLP policy violations cumulatively exceed a predetermined threshold, and (4) performing a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold. Various other methods, systems, and computer-readable media are also disclosed.

## Background
Individuals and entities increasingly share, access, and disseminate high volumes of electronic information. In addition, the ubiquity of high-speed Internet access, mobile devices, and portable storage has led to an increasingly mobile workforce. As a consequence, it has become more difficult than ever for organizations to prevent sensitive information from being lost and/or compromised.
For example, users may maliciously or unintentionally leak confidential data to unauthorized third parties via a variety of communication channels. In order to prevent these security breaches, conventional data loss prevention (DLP) systems typically monitor the flow of information over potentially insecure channels. When a security breach is detected, a DLP system may perform certain security measures, such as reporting the breach to administrators and/or preventing the offending user from accessing various networking, computing, and/or data resources.
Unfortunately, normal computing tasks performed by authorized users often result in accidental data leakage. However, if a DLP system detects and reports every such instance of data leakage, it will most likely report many false positives, and the resulting security measures performed by the DLP system may significantly disrupt the workflow of authorized users. While some DLP systems attempt to correct such over-reporting by relaxing their policies, malicious users may take advantage of these relaxed policies to periodically leak small portions of data over an extended period of time (a problem often referred to as “drip data leakage”), potentially resulting in significant data leaks. As such, the current disclosure identifies and addresses a need for more efficient and effective systems and methods for detecting data leaks.
SUMMARY
As will be described in greater detail below, the instant disclosure generally relates to systems and methods for both (1) detecting data leaks (by, e.g., tracking and accumulating both full and partial DLP policy violations) and (2) providing feedback to DLP administrators to restructure relaxed policies. In one example, a computer-implemented method for performing such a task may include (1) monitoring at least one data-distribution channel utilized by an entity, (2) detecting a plurality of full DLP policy violations and/or partial DLP policy violations committed by the entity by analyzing data distributed by the entity via the data-distribution channel, (3) determining that the entity's DLP policy violations cumulatively exceed a predetermined threshold, and (4) performing a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold.
In some embodiments, monitoring the data-distribution channel utilized by the entity may include identifying and associating a plurality of data-distribution channels utilized by a user. In these embodiments, the systems described herein may determine that the entity's DLP policy violations cumulatively exceed the predetermined threshold by determining that DLP policy violations from each of the data-distribution channels associated with the user cumulatively exceed the predetermined threshold. In such embodiments, the plurality of data-distribution channels may include a computing device and/or a web account. In addition, in such embodiments identifying the plurality of data-distribution channels may include identifying login credentials of the user, identifying an IP address of a computing device of the user, and/or identifying packets within messages distributed by the user.
In some examples, determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold may include assigning a weight to each DLP policy violation. The method may then include accumulating the weights of each DLP policy violation to determine that the cumulative weight exceeds the predetermined threshold. In these examples, the weight assigned to each DLP policy violation may be based on content of distributed data that violated the DLP policy, an amount of the distributed data, a recipient of the distributed data, a frequency with which the DLP policy violations occurred, a location at which the DLP policy violation occurred, and/or previous DLP policy violations committed by the entity.
In some embodiments, the predetermined threshold may include a number of DLP policy violations, an amount of distributed data that violates the DLP policies, and/or a frequency of distributed data that violates DLP policies. In some examples, performing the security action may include notifying the entity and/or an administrator that the entity's DLP policy violations cumulatively exceed the predetermined threshold, lowering the predetermined threshold for future DLP policy violations committed by the entity, and/or disabling the entity's access to the data-distribution channel and/or sensitive data.
In some embodiments, the method may further include determining that at least one DLP policy should be adjusted by analyzing DLP policy violations committed by multiple entities. The method may then include adjusting the DLP policy.
In one embodiment, a system for implementing the above-described method may include (1) a monitoring module that monitors at least one data-distribution channel utilized by an entity, (2) a detection module that detects a plurality of full DLP policy violations and/or partial DLP policy violations committed by the entity by analyzing data distributed by the entity via the data-distribution channel, (3) a determination module that determines that the entity's DLP policy violations cumulatively exceed a predetermined threshold, and (4) a security module that performs a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold. In addition, the system may include at least one processor configured to execute the monitoring module, the detection module, the determination module, and the security module.
In some examples, the above-described method may be encoded as computer-readable instructions on a non-transitory computer-readable medium. For example, a computer-readable medium may include one or more computer-executable instructions that, when executed by at least one processor of a computing device, may cause the computing device to (1) monitor at least one data-distribution channel utilized by an entity, (2) detect a plurality of full DLP policy violations and/or partial DLP policy violations committed by the entity by analyzing data distributed by the entity via the data-distribution channel, (3) determine that the entity's DLP policy violations cumulatively exceed a predetermined threshold, and (4) perform a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold.
Features from any of the above-mentioned embodiments may be used in combination with one another in accordance with the general principles described herein. These and other embodiments, features, and advantages will be more fully understood upon reading the following detailed description in conjunction with the accompanying drawings and claims.

DETAILED DESCRIPTION OF EXEMPLARY EMBODIMENTS
The present disclosure is generally directed to systems and methods for detecting data leaks. As will be explained in greater detail below, by identifying and accumulating multiple full and/or partial DLP policy violations, the disclosed systems and methods may detect drip data leaks that may have gone undetected using traditional DLP systems. In addition, these systems and methods may avoid disrupting the workflow of authorized users by performing a security action only when the aggregate of multiple DLP policy violations has exceeded a threshold.
The following will provide, with reference to FIGS. 1-2C, detailed descriptions of exemplary systems for detecting data leaks. Detailed descriptions of corresponding computer-implemented methods will also be provided in connection with FIG. 3. In addition, detailed descriptions of an exemplary computing system and network architecture capable of implementing one or more of the embodiments described herein will be provided in connection with FIGS. 4 and 5, respectively.
FIG. 1 is a block diagram of an exemplary system 100 for detecting data leaks. As illustrated in this figure, exemplary system 100 may include one or more modules 102 for performing one or more tasks. For example, and as will be explained in greater detail below, exemplary system 100 may include a monitoring module 104 that monitors at least one data-distribution channel utilized by an entity. Exemplary system 100 may also include a detection module 106 that detects a plurality of full and/or partial DLP policy violations committed by the entity by analyzing data distributed by the entity via the data-distribution channel.
In addition, and as will be described in greater detail below, exemplary system 100 may include a determination module 108 that determines that the entity's DLP policy violations cumulatively exceed a predetermined threshold. Exemplary system 100 may also include a security module 110 that performs a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold. Finally, exemplary system 100 may include a feedback module 112 that notifies DLP administrators of, and/or automatically adjusts, relaxed DLP policies that require adjustment. Although illustrated as separate elements, one or more of modules 102 in FIG. 1 may represent portions of a single module or application.
In certain embodiments, one or more of modules 102 in FIG. 1 may represent one or more software applications or programs that, when executed by a computing device, may cause the computing device to perform one or more tasks. For example, and as will be described in greater detail below, one or more of modules 102 may represent software modules stored and configured to run on one or more computing devices, such as the devices illustrated in FIGS. 2A-2C (e.g., computing device 202 and/or server 206), computing system 410 in FIG. 4, and/or portions of exemplary network architecture 500 in FIG. 5. One or more of modules 102 in FIG. 1 may also represent all or portions of one or more special-purpose computers configured to perform one or more tasks.
As illustrated in FIG. 1, exemplary system 100 may also include one or more databases, such as DLP database 120. As will be described in greater detail below, DLP database 120 may be configured to store DLP policies. DLP database 120 may also be configured to record partial and full DLP policy violations and/or weights assigned to DLP violations committed by an entity. In addition, DLP database 120 may store associations between users, computing devices, and/or web accounts that may distribute data.
DLP database 120 may represent portions of a single database or computing device or a plurality of databases or computing devices. For example, DLP database 120 may represent a portion of computing device 202 and/or server 206 in FIGS. 2A-2C, computing system 410 in FIG. 4, and/or portions of exemplary network architecture 500 in FIG. 5. Alternatively, DLP database 120 in FIG. 1 may represent one or more physically separate devices capable of being accessed by a computing device, such as server 206 in FIGS. 2A-2C, computing system 410 in FIG. 4, and/or portions of exemplary network architecture 500 in FIG. 5.
Exemplary system 100 in FIG. 1 may be implemented in a variety of ways. For example, all or a portion of exemplary system 100 may represent portions of exemplary system 200 in FIGS. 2A-2C. As shown in FIGS. 2A-2C, system 200 may include a computing device 202 in communication with a server 206 via a network 204. In one example, illustrated in FIG. 2A, computing device 202 may be programmed with all of modules 102 and/or DLP database 120. Alternatively, as illustrated in FIG. 2B, server 206 may be programmed with all of modules 102 and/or DLP database 120.
In some examples, the functionality of modules 102 may be implemented across both computing device 202 and server 206 to most effectively detect data leaks. For example, as illustrated in FIG. 2C, one or more of modules 102 may be hosted and executed on both computing device 202 and server 206. In one embodiment, monitoring module 104 may be hosted on computing device 202 in order to identify data-distribution channels utilized by a user of computing device 202. Detection module 106 may be hosted and executed on both computing device 202 and server 206, as sensitive data may be distributed by the user from a computing device to server 206. In addition, determination module 108 may be implemented solely on server 206, as accumulating the DLP policy violations may be the most resource-intensive step of data leak detection process. Furthermore, security module 110 may be hosted and executed solely on computing device 202 in order to disable the user from distributing data via computing device 202. Finally, feedback module 112 may be implemented on both computing device 202 and server 206 in order to analyze DLP policy violations committed by multiple entities.
In one embodiment, one or more of modules 102 from FIG. 1 may, when executed by at least one processor of computing device 202 and/or server 206, enable computing device 202 and/or server 206 to detect data leaks. For example, and as will be described in greater detail below, monitoring module 104 may cause computing device 202 and/or server 206 to monitor at least one data-distribution channel (e.g., data distribution channel 208) utilized by an entity (e.g., computing device 202 and/or a user of the same). Detection module 106 may also cause computing device 202 and/or server 206 to detect a plurality of full and/or partial DLP policy violations (e.g., DLP policy violations 210) committed this entity by analyzing data distributed by the entity via the data-distribution channel. Next, determination module 108 may cause computing device 202 and/or server 206 to determine that the entity's DLP policy violations cumulatively exceed a predetermined threshold. In addition, security module 110 may cause computing device 202 and/or server 206 to perform a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold.
In addition, FIGS. 2A and 2B show several examples of data flow between modules 102. In one example, monitoring module 104 may monitor data-distribution channel 208 by sending and receiving information to and from data-distribution channel 208. Monitoring module 104 and detection module 106 may then communicate back and forth in order for detection module 106 to detect DLP policy violations. In another embodiment, monitoring module 104 may receive information from data-distribution channel 208 and may then pass on the information to detection module 106. In addition, detection module 106 may communicate directly with data-distribution channel 208.
Computing device 202 generally represents any type or form of computing device capable of reading computer-executable instructions. Examples of computing device 202 include, without limitation, laptops, tablets, desktops, servers, cellular phones, Personal Digital Assistants (PDAs), multimedia players, embedded systems, wearable devices (e.g., smart watches, smart glasses, etc.), gaming consoles, combinations of one or more of the same, exemplary computing system 410 in FIG. 4, or any other suitable computing device.
Server 206 generally represents any type or form of computing device that is capable of identifying and/or analyzing data that is related to a DLP policy and/or an entity that may commit a DLP policy violation. Examples of server 206 include, without limitation, application servers, database servers, network servers, and messaging servers configured to provide various database and/or web services and/or run certain software applications.
Network 204 generally represents any medium or architecture capable of facilitating communication or data transfer. Examples of network 204 include, without limitation, an intranet, a Wide Area Network (WAN), a Local Area Network (LAN), a Personal Area Network (PAN), the Internet, Power Line Communications (PLC), a cellular network (e.g., a Global System for Mobile Communications (GSM) network), exemplary network architecture 500 in FIG. 5, or the like. Network 204 may facilitate communication or data transfer using wireless or wired connections. In one embodiment, network 204 may facilitate communication between computing device 202 and server 206.
FIG. 3 is a flow diagram of an exemplary computer-implemented method 300 for detecting data leaks. The steps shown in FIG. 3 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 3 may be performed by one or more of the components of system 100 in FIG. 1, system 200 in FIGS. 2A-2C, computing system 410 in FIG. 4, and/or portions of exemplary network architecture 500 in FIG. 5.
As illustrated in FIG. 3, at step 302 one or more of the systems described herein may monitor at least one data-distribution channel utilized by an entity. For example, monitoring module 104 may, as part of computing device 202 and/or server 206 in FIGS. 2A-2C, monitor a data-distribution channel 208 utilized by an entity.
The term “entity,” as used herein, generally refers to any type or form of computing device, server, web account, application, or combinations thereof or user of the same, that is capable of distributing data via one or more data-distribution channels. For example, an entity may be a computing device or a user of a computing device. In addition, an entity may be the combination of a user and multiple communication channels associated with the user.
In addition, the phrase “data-distribution channel,” as used herein, generally refers to any type or form of communication pathway, computing system, and/or executable code capable of dispersing digital information from one entity to another. Examples of data-distribution channels include, without limitation, computing devices, mobile communication devices, email accounts, text-messaging services, social networking platforms, Internet and Ethernet networks, servers, and/or any other suitable communication channel.
The systems described herein may monitor the data-distribution channel utilized by the entity in a variety of ways. In some examples, monitoring module 104 may identify and monitor a single data-distribution channel of an entity, such as by monitoring messages received by and distributed from a particular messaging account. In other examples, monitoring module 104 may identify and associate a plurality of data-distribution channels utilized by an entity. For example, monitoring module 104 may identify one or more computing devices and/or web accounts (e.g., email accounts, social networking accounts, etc.) that belong to a user. Monitoring module 104 may then form an association between the multiple data-distribution channels in order to detect data leaks committed by the user from multiple access points. In some examples, monitoring module 104 may store associations between multiple data-distribution channels utilized by an entity in DLP database 120.
In some embodiments, monitoring module 104 may identify the data-distribution channel utilized by the entity by identifying unique attributes that are indicative of a particular entity. For example, monitoring module 104 may identify a computing device of a user by identifying the login credentials that the user enters to access the computing device and/or by identifying an IP address of the computing device. In addition, monitoring module 104 may identify packets within messages distributed via a web account of the user that indicate the web account from which the messages were distributed. In some examples, identifying unique attributes that are indicative of a particular identify may allow monitoring module 104 to determine precisely which user distributed sensitive data from within a group of users (e.g., employees within an organization) that distribute data via the same network and/or server cluster.
Furthermore, monitoring module 104 may identify a geographical location that is unique to or indicative of the user, a personal (i.e., non-work related) computing device of the user, a mobile communication device of the user, and/or any additional identifier and/or data-distribution channel associated with an entity. Some malicious users may distribute sensitive data via a variety of channels in order to avoid detection. However, by identifying and monitoring a combination of the above-described data-distribution channels, the systems and methods described herein may detect data leaks committed by an entity whether the entity distributes sensitive data from a workplace, from home, while travelling, via a personal computer or cell phone, via an email account, via a social networking platform, and/or any other data-distribution channel.
Once monitoring module 104 has identified data-distribution channel 208, monitoring module 104 may monitor data-distribution channel 208 in a variety of ways. For example, if data-distribution channel 208 is a web account, monitoring module 104 may monitor data-distribution channel 208 by identifying messages and/or attachments within messages distributed by the entity. If data-distribution channel 208 is a computing device, monitoring module 104 may monitor files downloaded to and/or uploaded from the computing device Monitoring module 104 may also monitor files transferred to and from the computing device. In general, monitoring module 104 may monitor any type of data-distribution channel by identifying data distributed via the channel.
Returning to FIG. 3, at step 304 the one or more of systems described herein may detect a plurality of full DLP policy violations and/or partial DLP policy violations committed by the entity by analyzing data distributed by the entity via the data-distribution channel. For example, detection module 106 may detect DLP policy violations 210 committed by the entity by analyzing data distributed via data-distribution channel 208.
The systems described herein may analyze data distributed by the entity to detect DLP policy violations committed by the entity in a variety of ways. For example, detection module 106 may analyze the distributed data using Described Content Matching (DCM), Indexed Data Matching (IDM), Exact Data Matching (EDM), and/or Vector Machine Learning (VML) technologies.
In some embodiments, detection module 106 may further analyze the distributed data by identifying the recipient of the distributed data. Additionally or alternatively, detection module 106 may determine the amount (e.g., number of files and/or the size of the files) of distributed data, the location from which the data was distributed (e.g., a particular computing device or a geographical location), the time (e.g., during work hours or on a weekend), a frequency with which the entity distributes sensitive data, and/or any additional attribute of the distributed data that may indicate a data leak.
Once detection module 106 has analyzed the data distributed by the entity, detection module 106 may determine whether the entity has committed a DLP policy violation based on the analysis. For example, detection module 106 may compare the results of the analysis to a set of DLP policies stored in DLP database 120. The DLP policies may impose any set of restrictions on data distribution by an entity, such as limiting the amount and/or the content of distributed data. In addition, the DLP policies may take into consideration the position (e.g., security clearance or role within an organization) of the distributor and/or the receiver of the data, as well as any additional attribute of the distributed data, such as the location from which the data was distributed and/or the time at which the data was distributed. The DLP policies may be any set of DLP policies already implemented within an organization and/or they may be customized and tailored to embodiments of the present disclosure.
For example, a DLP policy may state that an entity may not distribute more than 1 MB of sensitive data to an unauthorized party. In this example, detection module 106 may determine that a user is attempting to send an email containing an attached file marked “confidential.” In addition, detection module 106 may determine that the intended recipient has a low security clearance (i.e., unauthorized to view sensitive data) and that the confidential attachment contains 1.2 MB of data. Based on those determinations, detection module 106 may then determine that the user is violating a DLP policy by distributing more than 1 MB of confidential data to an unauthorized party.
In some embodiments, detection module 106 may determine whether distributed data partially or fully violates a DLP policy. In the above example, detection module 106 may determine that the user is fully violating the DLP policy because the confidential attachment contains more than 1 MB of data. However, in another example, the user may only distribute 0.8 MB of data to an unauthorized user. In this case, detection module 106 may determine that the user has only partially violated the DLP policy.
As an additional example, a set of DLP policies may contain a policy that restricts a user from distributing the credit card information of more than 50 customers via any data-distribution channel. If the user distributes the credit card information of 25 customers via a removable device and later distributes the credit card information of an additional 26 customers via a messaging account, detection module 106 may determine that the user has partially violated the DLP policy twice. Since the user distributed the credit card information of more than 50 customers in total, detection module 106 may record the two partial DLP policy violations as a full DLP policy violation. In general, detection module 106 may record a full DLP policy violation in response to detecting any combination of partial violations that amount to a full violation.
In addition to detecting full and partial DLP policy violations, detection module 106 may record the time and severity of each DLP policy violation committed by an entity in DLP database 120. Traditional DLP systems may only detect and/or mitigate full DLP policy violations; however, by identifying and recording partial DLP policy violations, the systems described herein may detect legitimate data leaks that comprise multiple smaller data distributions over an extended period of time.
Returning to FIG. 3, at step 306 one or more of the systems described herein may determine that the entity's DLP policy violations cumulatively exceed a predetermined threshold. For example, determination module 108 may determine that DLP policy violations 210 cumulatively exceed the predetermined threshold.
The systems described herein may determine that the entity's DLP policy violations cumulatively exceed a predetermined threshold in a variety of ways. In some examples, determination module 108 may determine that the DLP policy violations from a single data-distribution channel cumulatively exceed the predetermined threshold. However, if monitoring module 104 identified and associated a plurality of data-distribution channels associated with a user, determination module 108 may determine that the DLP policy violations from each of the data-distribution channels associated with the user cumulatively exceed the predetermined threshold.
In some embodiments, determination module 108 may accumulate the entity's DLP policy violations by assigning a weight to each DLP policy violation and accumulating each assigned weight. For example, if an entity has partially violated a DLP policy, determination module 108 may quantify the degree to which the entity violated the policy and/or the relative threat imposed by the DLP policy violation by assigning a numerical weight to the violation. In some embodiments, the weight assigned to each DLP policy violation may be based on content of the distributed data that violated the DLP policy, an amount of the distributed data, a recipient of the distributed data, a frequency with which the DLP policy occurred, a location at which the DLP policy violation occurred, previous DLP policy violations committed by the entity, and/or any additional measure of the violation
For example, if an entity partially violates a DLP policy prohibiting the distribution of more than 5 MB of sensitive data by distributing 2 MB of sensitive data, determination module 108 may assign a weight of “0.4” (i.e., 2 MB/5 MB) to the violated DLP policy.
In some examples, the predetermined threshold may be based on the weights assigned to each DLP policy violation. For example, determination module 108 may weight and accumulate partial and full DLP policy violations until the cumulative weight reaches “1” (e.g., the weight assigned to a full violation). Additionally or alternatively, the predetermined threshold may be based on a cumulative number (e.g., 4 partial violations or 2 full violations) of DLP policy violations, an amount (e.g., 10 MB) of distributed data that violates DLP policies and/or a frequency (e.g., 10 MB/month) of distributed data that violates DLP policies. The predetermined threshold may be based on any combination of weights, numbers, amounts, frequencies, or additional metrics used to quantify DLP policy violations.
Returning to FIG. 3, at step 308 one or more of the systems described herein may perform a security action in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold. For example, security module 110 may perform a security action in response to determining that DLP policy violations 210 exceed the predetermined threshold.
The systems described herein may perform a variety of security actions in response to determining that the entity's DLP policy violations cumulatively exceed the predetermined threshold. For example, the entity may have accidentally committed and/or may be unaware of committing the DLP policy violations. As such, security module 110 may first notify the entity that the entity's DLP policy violations cumulatively exceed the predetermined threshold so that the entity can take appropriate action to prevent future accidental data leaks. Security module 110 may also lower the threshold for future DLP policy violations and/or perform a more severe security action following future DLP policy violations committed by the entity.
Additionally or alternatively, security module 110 may notify an administrator that the entity's DLP policy violations cumulatively exceed the predetermined threshold. Security module 110 may also disable the entity's access to one or more data-distribution channels and/or sensitive data, such as by disabling the entity's access a computing device and/or the Internet. In addition, security module 110 may perform any other suitable security measure to prevent further data leaks.
Furthermore, the systems described herein may monitor and analyze data-distribution channels and DLP policy violations associated with multiple entities within an organization. As a result of this analysis, feedback module 112 may detect trends of data-distribution behavior and may use such trends to adjust DLP policies and/or predetermined thresholds.
For example, feedback module 112 may determine that multiple users within an organization frequently partially and/or fully violate particular DLP policies. Feedback module 112 may then automatically restructure and/or suggest to an administrator to restructure the DLP policies by adding, removing, or modifying the rules within the policies. Specifically, feedback module 112 may remove or lower (or suggest to an administrator to remove or lower) the weights assigned to the policy violations if determination module 108 determines that the distributed data that violated the DLP policies does not actually pose a security threat. Additionally or alternatively, feedback module 112 may add policies and/or increase the weights assigned to the policy violations (or suggest to an administrator to add policies and/or increase the weights assigned to the policy violations) if feedback module 112 determines that the partial DLP policy violations indicate a legitimate data leak.
Similarly, feedback module 112 may configure (or suggest to an administrator to configure) the weights assigned to policy violations and/or the predetermined thresholds to be applicable for a predetermined amount of time, such as a day, a week, or a month. For example, feedback module 112 may temporarily impose a lower threshold on a particular user, as a warning or probationary measure, in response to the user having previously violated DLP policies. Additionally or alternatively, feedback module 112 may increase or remove the threshold for a particular user if the user has a legitimate requirement to share sensitive data. Feedback module 112 may adjust one or more DLP policies and/or predetermined thresholds in any suitable manner to more effectively detect data leaks.
The systems and methods disclosed herein may be implemented in a variety of ways and provide a number of advantages. For example, by associating multiple data-distribution channels utilized by an entity, the systems and methods described herein may detect sensitive data distributed via a variety of channels by a single user. In addition, the systems and methods described herein may detect drip data leaks by identifying and accumulating multiple small data leaks. Furthermore, by waiting to perform a security action until after an entity exceeds a predetermined threshold, the disclosed systems and methods may reduce unnecessary and bothersome DLP prevention measures while not sacrificing the strictness of DLP policies.
FIG. 4 is a block diagram of an exemplary computing system 410 capable of implementing one or more of the embodiments described and/or illustrated herein. For example, all or a portion of computing system 410 may perform and/or be a means for performing, either alone or in combination with other elements, one or more of the steps described herein (such as one or more of the steps illustrated in FIG. 3). All or a portion of computing system 410 may also perform and/or be a means for performing any other steps, methods, or processes described and/or illustrated herein.
Computing system 410 broadly represents any single or multi-processor computing device or system capable of executing computer-readable instructions.
