## Abstract

The disclosed computer-implemented method for capturing input from users to prevent data loss may include (1) intercepting, as part of a data-loss-prevention application, user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a data-loss-prevention policy, (2) upon intercepting the user input, causing the data-processing application to perform an alternative operation on the data that makes the data accessible to the data-loss-prevention application, (3) scanning, while the data-processing application is prevented from performing the operation, the data for compliance with the data-loss-prevention policy, (4) determining, based on a result of the scanning, that the data complies with the data-loss-prevention policy, and (5) causing, in response to determining that the data complies with the data-loss-prevention policy, the data-processing application to perform the operation. Various other methods, systems, and computer-readable media are also disclosed.

## Background
BACKGROUND
The ease with which digital information may be disseminated may create challenges for individuals and organizations concerned with preventing the loss of sensitive data. Individuals and organizations are therefore increasingly looking to data-loss-prevention (DLP) solutions to protect their sensitive data. Some DLP solutions may be directed to monitoring applications that disseminate content, such as email applications, to detect and prevent the dissemination of sensitive content by the monitored applications. Traditional DLP solutions may monitor such applications by loading, into the applications, add-ins that monitor the applications' activities. However, not all content-disseminating applications allow the use of add-ins. As a result, traditional DLP solutions may fail to prevent applications that do not allow the use of add-ins from disseminating sensitive content. The instant application, therefore, identifies the need for improved DLP solutions that do not require the use of add-ins.
SUMMARY
As will be described in greater detail below, the instant disclosure describes various systems and methods for capturing input from users to prevent data loss. In one example, a computer-implemented method for capturing input from users to prevent data loss may include (1) intercepting, as part of a DLP application, user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a DLP policy, (2) upon intercepting the user input, causing the data-processing application to perform an alternative operation on the data that makes the data accessible to the DLP application, (3) scanning, while the data-processing application is prevented from performing the operation, the data for compliance with the DLP policy, (4) determining, based on a result of the scanning, that the data complies with the DLP policy, and (5) causing, in response to determining that the data complies with the DLP policy, the data-processing application to perform the operation. In one embodiment, the DLP application may be separate and distinct from the data-processing application.
In some embodiments, the data may include an email, and the data-processing application may include an email application. In these embodiments, intercepting the user input intended for the data-processing application may include intercepting user input intended for the email application that would, if received by the email application, cause the email application to send the email to a location designated by a user of the email application. Additionally or alternatively, causing the data-processing application to perform the alternative operation may include causing the email application to save the email to a location accessible to the DLP application. Additionally or alternatively, scanning the data for compliance with the DLP policy may include scanning the email for compliance with the DLP policy. Additionally or alternatively, causing the data-processing application to perform the operation may include causing the email application to send the email to the location designated by the user.
In one example, causing the email application to save the email may include sending a command to the email application to save the email. In this example, causing the email application to send the email to the location designated by the user may include sending a command to the email application to send the email. In some examples, intercepting the user input may include intercepting the user input in response to determining that the email application does not support add-ins capable of performing capturing outgoing email data and/or add-ins capable of preventing send operations.
In some examples, intercepting the user input may include temporarily preventing the data-processing application from performing the operation that may violate the DLP policy. In some embodiments, causing the data-processing application to perform the alternative operation may include (1) generating an alternative input that would, if received by the data-processing application, cause the data-processing application to perform the alternative operation and (2) sending the alternative input to the data-processing application instead of the user input.
In some examples, intercepting the user input intended for the data-processing application may include intercepting, as part of the DLP application, a mouse event intended for the data-processing application that would, if received by the data-processing application, cause the data-processing application to perform the operation. Additionally or alternatively, intercepting the user input intended for the data-processing application may include intercepting, as part of the DLP application, a keyboard event intended for the data-processing application that would, if received by the data-processing application, cause the data-processing application to perform the operation.
In one embodiment, the computer-implemented method may further include (1) intercepting, as part of the DLP application, additional user input intended for the data-processing application that would, if received by the data-processing application, cause the data-processing application to perform the operation on additional data, (2) upon intercepting the additional user input, causing the data-processing application to perform the alternative operation on the additional data that makes the additional data accessible to the DLP application, (3) scanning, while the data-processing application is prevented from performing the operation, the additional data for compliance with the DLP policy, (4) determining, based on a result of the scanning, that the additional data does not comply with an element of the DLP policy, and (5) initiating a DLP action in response to determining that the additional data does not comply with the element of the DLP policy.
In one embodiment, the DLP action may include informing a user of the data-processing application that the additional data does not comply with the element of the DLP policy. Additionally or alternatively, the DLP action may include informing the user that the operation will not be performed on the additional data. Additionally or alternatively, the DLP action may include informing an administrator of the data-processing application that the user has attempted to perform the operation on data that does not comply with the element of the DLP policy. Additionally or alternatively, the DLP action may include permanently blocking the data-processing application from performing the operation on the additional data.
In one example, the DLP application may represent a printer application. Additionally or alternatively, the DLP application may represent a screen capturing application. Additionally or alternatively, the DLP application may represent a word processor application. In some examples, the operation may include (1) printing the data, (2) taking a screenshot of the data, (3) copying the data, and/or (4) pasting the data.
In one embodiment, a system for implementing the above-described method may include (1) an interception module, stored in memory, that intercepts, as part of a DLP application, user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a DLP policy, (2) a causation module, stored in memory, that, upon intercepting the user input, causes the data-processing application to perform an alternative operation on the data that makes the data accessible to the DLP application, (3) a scanning module, stored in memory, that scans, while the data-processing application is prevented from performing the operation, the data for compliance with the DLP policy, (4) a determination module, stored in memory, that determines, based on a result of the scanning, that the data complies with the DLP policy, and (5) a physical processor configured to execute the interception module, the causation module, the scanning module, and the determination module. In this embodiment, the causation module may also cause, in response to the determination module determining that the data complies with the DLP policy, the data-processing application to perform the operation.
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 a processor of a computing device, may cause the computing device to (1) intercept, as part of a DLP application, user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a DLP policy, (2) upon intercepting the user input, cause the data-processing application to perform an alternative operation on the data that makes the data accessible to the DLP application, (3) scan, while the data-processing application is prevented from performing the operation, the data for compliance with the DLP policy, (4) determine, based on a result of the scanning, that the data complies with the DLP policy, and (5) cause, in response to determining that the data complies with the DLP policy, the data-processing application to perform the operation.
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 capturing input from users to prevent data loss. As will be explained in greater detail below, by (1) capturing user input that, once received by an application, may trigger the application to disseminate certain information and (2) sending alternative user input to the application in place of the user input that makes the information available to a DLP application for scanning, the systems and methods may effectively prevent the application from disseminating potentially sensitive information. In some examples, the disclosed systems and methods may capture user input intended to trigger an email application to send an email. In these examples, the disclosed systems and methods may prevent the email application from receiving the user input and, instead, may send alternative user input to the email application that instructs the email application to save the email to a location accessible by a DLP application such that the DLP application may scan the email for compliance with a DLP policy.
The following will provide, with reference to FIGS. 1, 2, 4, and 5 detailed descriptions of exemplary systems for capturing input from users to prevent data loss. Detailed descriptions of corresponding computer-implemented methods will also be provided in connection with FIGS. 3 and 6. 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. 7 and 8, respectively.
FIG. 1 is a block diagram of exemplary system 100 for capturing input from users to prevent data loss. 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 an interception module 104 that may intercept user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a DLP policy. Exemplary system 100 may additionally include a causation module 106 that may cause, upon intercepting the user input, the data-processing application to perform an alternative operation on the data that makes the data accessible to the DLP application.
Exemplary system 100 may also include a scanning module 108 that may scan, while the data-processing application is prevented from performing the operation, the data for compliance with the DLP policy. Exemplary system 100 may additionally include a determination module 110 that may determine, based on a result of the scanning, that the data complies with the DLP policy. In some examples, causation module 106 may further cause, in response to determining that the data complies with the DLP policy, the data-processing application to perform the operation. 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 FIG. 2 (e.g., computing device 202 and/or server 206), computing system 710 in FIG. 7, and/or portions of exemplary network architecture 800 in FIG. 8. 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 database 120. In one example, database 120 may be configured to store one or more DLP policies, such as DLP policy 122. Database 120 may represent portions of a single database or computing device or a plurality of databases or computing devices. For example, database 120 may represent a portion of computing device 202 in FIG. 2, computing system 710 in FIG. 7, and/or portions of exemplary network architecture 800 in FIG. 8. Alternatively, 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 FIG. 2, computing system 710 in FIG. 7, and/or portions of exemplary network architecture 800 in FIG. 8.
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 FIG. 2. As shown in FIG. 2, system 200 may include a computing device 202 in communication with a server 206 via a network 204. In one example, computing device 202 may be programmed with one or more of modules 102 and/or may store all or a portion of the data in database 120. Additionally or alternatively, server 206 may be programmed with one or more of modules 102 and/or may store all or a portion of the data in database 120.
In one embodiment, one or more of modules 102 from FIG. 1 may, when executed by a processor of computing device 202 and/or server 206, enable computing device 202 and/or server 206 to capture input from users to prevent data loss. For example, and as will be described in greater detail below, interception module 104 may intercept, as part of a DLP application 208, user input 210 intended for a data-processing application 212 that would, if received by data-processing application 212, cause data-processing application 212 to perform an operation on data 214 that may violate a DLP policy 122. Causation module 106 may then cause data-processing application 212 to perform an alternative operation on data 214 that makes data 214 accessible to DLP application 208. Scanning module 108 may then scan, while data-processing application 212 is prevented from performing the operation, data 214 for compliance with DLP policy 122. Determination module 110 may then determine, based on a result of the scanning, that data 214 complies with DLP policy 122. Causation module 106 may then cause, in response to the determination that data 214 complies with DLP policy 122, data-processing application 212 to perform the operation.
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 710 in FIG. 7, or any other suitable computing device.
Server 206 generally represents any type or form of computing device that is capable of reading computer-executable instructions. Examples of server 206 include, without limitation, application servers and database servers configured to provide various database 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 800 in FIG. 8, 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 capturing input from users to prevent data loss. 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 FIG. 2, system 400 in FIG. 4, system 500 in FIG. 5, computing system 710 in FIG. 7, and/or portions of exemplary network architecture 800 in FIG. 8.
As illustrated in FIG. 3, at step 302, one or more of the systems described herein may intercept, as part of a DLP application, user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a DLP policy. For example, interception module 104 may, as part of DLP application 208 running on computing device 202 in FIG. 2, intercept user input 210 intended for data-processing application 212 that would, if received by data-processing application 212, cause data-processing application 212 to perform an operation on data 214 that may violate DLP policy 122.
Interception module 104 may intercept user input intended for a data-processing application as part of a DLP application. As used herein, the term “data-loss-prevention application” generally refers to any application that guards against the unauthorized distribution of sensitive information. In some examples, a DLP application may monitor a data-processing application to detect and prevent activities that may breach a DLP policy. In some examples, the DLP application may function as a filter that only allows the data-processing application to disseminate content that satisfies the criteria set forth in the DLP policy.
In some examples, the systems and methods disclosed herein may, as part of a DLP application, indirectly monitor a data-processing application to detect and prevent activities that may breach a DLP policy. For example, the systems and methods disclosed herein may, as part of a DLP application, monitor a data-processing application by monitoring user inputs intended for the data-processing application before the user inputs are received by the data-processing application. In some examples, the DLP application may operate as part of a DLP service provided by a security-service provider. Additionally or alternatively, the DLP application may operate as part of antivirus software.
In some examples, a DLP application may be separate and distinct from the applications that the DLP application is intended to monitor. For example, the DLP application described herein may differ from traditional DLP solutions that are integrated directly into the applications which the DLP solutions are intended to monitor. By utilizing a DLP application that is separate and distinct from the application that the DLP application is intended to monitor, the disclosed systems and methods may effectively monitor applications that do not allow for the integration of DLP applications. For example, the disclosed systems and methods may utilize the DLP application to effectively monitor applications that do not allow for DLP add-ins.
As used herein, the term “data-loss-prevention policy” generally refers to any policy directed at preventing the unauthorized distribution of sensitive information. Examples of sensitive information may include, without limitation, confidential business information, financial information, intellectual-property information, patient information, credit-card information, and/or any other information and/or class of information determined to be sensitive by the disclosed systems and methods. In some examples, a DLP policy may specify specific information that may not be distributed. For example, a DLP policy may specify a particular document and/or certain language that may not be distributed. Additionally or alternatively, a DLP policy may specify a type of information that may not be distributed. For example, a DLP policy may specify that confidential business information may not be distributed.
In some examples, a DLP policy may specify parties that are authorized and/or unauthorized to distribute a specified content and/or type of content. For example, a DLP policy may specify that management personnel are authorized to distribute confidential business information but that non-management personnel are not authorized to distribute confidential business information. Additionally or alternatively, a DLP policy may further specify locations to which the specified content and/or type of content may or may not be distributed. For example, a DLP policy may specify that a particular document may be distributed to company email addresses but may not be distributed to non-company email addresses.
Interception module 104 may intercept user input intended for a variety of data-processing applications. As used herein, the term “data-processing application” may refer to any application that a user may use to create, access, disseminate, and/or otherwise process data and/or any application that performs operations on data that may violate a DLP policy. For example, a data-processing application may refer to an application capable of disseminating potentially confidential information. Examples of data-processing applications may include, without limitation, email applications, screen-capturing applications, and/or word-processor applications.
Interception module 104 may intercept user input that may cause a data-processing application to perform various kinds of operations on data that may violate a DLP policy. The term “operation,” as used herein, generally refers to any task that may be executed by a computer. Examples of operations that may potentially violate a DLP policy include, without limitation, emailing data, printing data, taking a screenshot of data, copying data, saving data, and/or pasting data. In some examples, interception module 104 may intercept user input directed at sending an email. For example, data-processing application 212 may represent an email application that operates as part of an email platform, such as APPLE MAIL, OUTLOOK, GMAIL, YAHOO, etc., and data 214 may represent an email that a user of the email application is attempting to send via the email application. In these examples, interception module 104 may intercept input from the user of the email application that would, if received by the email application, cause the email application to send the email to a location designated by the user. For example, as illustrated in FIG. 4, interception module 104 may, as part of DLP application 208, intercept input from a user of an email application 402 that would, if received by email application 402, cause email application 402 to send an email 404.
In some examples, a data-processing application may be configured to perform operations that may violate a DLP policy in response to receiving user input from a user of the data-processing application. As used herein, the term “user input” generally refers to any input received from a user through an input device, such as a keyboard or a mouse. Examples of user input include, without limitation, a mouse event, such as a mouse click, and/or a keyboard event, such as a command from a keyboard.
Interception module 104 may intercept various kinds of user input that may cause a data-processing application to perform an operation on data that may violate a DLP policy. For example, interception module 104 may intercept a mouse or a keyboard event intended for data-processing application 212 that would, if received by data-processing application 212, cause data-processing application 212 to perform an operation on data 214. Using FIG. 4 as an example, interception module 104 may intercept a mouse click corresponding to a send button displayed within email application 402. In this example, a user may have submitted the mouse click, and the mouse click may, if received by email application 402, trigger email application 402 to send email 404. Using FIG. 4 as another example, interception module 104 may intercept a keyboard command, such as “cmd+return.” In this example, a user may have submitted the command “cmd+return,” and the command may, if received by email application 402, trigger email application 402 to send email 404.
In some examples, interception module 104 may intercept a user input by utilizing a component of an operating system (e.g., APPLE's QUARTZ EVENT SERVICES) that allows user-input events destined for data-processing applications to be monitored and filtered. Using FIG. 5 as an example, interception module 104 may receive information relating to user input 210 from an operating system component 502 of computing device 202. In some examples, operating system component 502 may be configured to (1) identify inputs from users, (2) determine to which applications the users are intending to submit the inputs, and (3) relay the inputs to the appropriate applications. In some examples, interception module 104 may register with operating system component 502 to receive the user inputs intended for a data-processing application before or instead of the data-processing application.
In some examples, interception module 104 may interface with an application accessibility application programming interface (API) (e.g., APPLE's OS X Accessibility API) to determine what operation a received user input (e.g., a mouse click) would trigger if received by a data-processing application. Using FIG. 5 as an example, interception module 104 may interface with an application accessibility API 504 to determine what operation user input 210 would trigger if received by data-processing application 212.
In some examples, interception module 104 may, as part of intercepting user input, temporarily prevent a data-processing application from receiving the user input. In one example, by temporarily preventing a data-processing application from receiving a user input, interception module 104 may prevent the data-processing application from performing an operation that the user input would have otherwise triggered and that may violate a DLP policy. As will be explained below, the systems and methods disclosed herein may later allow the data-processing application to perform the operation on the data after it is determined that the operation will not violate a DLP policy. Using FIG. 4 as an example, interception module 104 may prevent email application 402 from receiving user input 210, thereby temporarily preventing email application 402 from sending email 404.
In some examples, interception module 104 may intercept user input in response to determining that a data-processing application does not support certain add-ins. Using FIG. 4 as an example, interception module 104 may intercept user input 210 in response to determining that email application 402 does not support add-ins capable of capturing outgoing email data. In another example, interception module 104 may intercept user input in response to determining that email application 402 does not support add-ins capable of preventing send operations.
Returning to FIG. 3, at step 304, one or more of the systems described herein may cause, upon intercepting the user input, the data-processing application to perform an alternative operation on the data that makes the data accessible to the DLP application. For example, causation module 106 may, as part of computing device 202 in FIG. 2 cause data-processing application 212 to perform an alternative operation on data 214 that makes data 214 accessible to DLP application 208.
As used herein, the term “alternative operation” may refer to any computer-executed task that a data-processing application may perform that will make data from the data-processing application available to a DLP application for DLP processing. Examples of alternative operations include, without limitation, save and/or send operations. For example, an email application may perform an alternative operation on an email by saving the email to a location accessible to a DLP application and/or by sending (e.g., via an inter-process communication channel) the email to the DLP application.
Causation module 106 may cause a data-processing application to perform an alternative operation in a variety of ways. In some examples, causation module 106 may cause a data-processing application to perform an alternative operation by (1) generating an alternative user input that will, when received by the data-processing application, cause the data-processing application to perform the alternative operation and (2) sending the alternative user input to the data-processing application. Using FIG. 4 as an example, user input 210 may represent user input that would, if received by email application 402, cause email application 402 to send email 404, as discussed above. In this example, causation module 106 may generate an alternative user input that will, when received by email application 402, cause email application 402 to save email 404 to a location accessible to DLP application 208. Causation module 106 may then send the alternative user input to email application 402 instead of sending user input 210 to email application 402, thereby causing email application 402 to save email 404 instead of sending email 404. In some examples, causation module 106 may send the alternative user input to email application 402 by sending a mouse or a keyboard event that is associated with a save command of email application 402. For example, causation module 106 may send the command “cmd+s” to email application 402 to cause email application 402 to save email 404.
Returning to FIG. 3, at step 306, one or more of the systems described herein may, while the data-processing application is prevented from performing the operation, scan the data for compliance with the DLP policy. For example, scanning module 108 may, as part of computing device 202 in FIG. 2, scan data 214 for compliance with DLP policy 122 while data-processing application 212 is prevented from performing the operation associated with user input 210.
Scanning module 108 may scan data in a variety of ways. In general, scanning module 108 may scan data for compliance with a DLP policy after causation module 106 has caused a data-processing application to perform an alternative operation on the data by (1) accessing the data and (2) analyzing the data and/or a pending operation that may be performed on the data for violations of the DLP policy. In instances where the alternative operation includes saving the data to a location accessible to a DLP application, scanning module 108 may read, as part of the DLP application, the saved data from the location. In some examples, scanning module 108 may access the data by receiving the data from a data-processing application via an inter-application communication channel. In at least one example, causation module 106 may utilize a scripting language (e.g., APPLE's APPLESCRIPT) to access the data.
In some examples, scanning module 108 may analyze data and/or a pending operation that may be performed on the data for violations of a DLP policy. Additionally or alternatively, scanning module 108 may send the data to a remote service for DLP processing. For example, as shown in FIG. 5, scanning module 108 may send data 214 to a violation-detection engine 506. In this example, violation-detection engine 506 may scan data 214 for violations of a DLP policy.
At step 308, one or more of the systems described herein may determine, based on a result of the scanning performed at step 306, that the data complies with the DLP policy. For example, determination module 110 may, as part of computing device 202 in FIG. 2, determine that data 214 complies with DLP policy 122.
Determination module 110 may determine that data complies with a DLP policy in a variety of ways. For example, determination module 110 may determine that data 214 complies with DLP policy 122 based on a result of the scanning performed at step 306. For example, if scanning module 108 scanned data 214 for specific words and/or phrases that DLP policy 122 designates as sensitive, determination module 110 may determine that data 214 complies with DLP policy 122 if data 214 does not include the specific words and/or phrases. Additionally or alternatively, if scanning module 108 scanned data 214 for information that identifies an intended location to which data 214 is to be disseminated, determination module 110 may determine that data 214 complies with DLP policy 122 if DLP policy 122 does not designate the identified intended location as unauthorized and/or if DLP policy 122 designates the identified intended location as authorized. Additionally or alternatively, if scanning module 108 scanned data 214 for information that identifies an intended recipient to whom data 214 is to be disseminated, determination module 110 may determine that data 214 complies with DLP policy 122 if DLP policy 122 does not designate the identified intended recipient as unauthorized and/or if DLP policy 122 designates the identified intended recipient as authorized.
At step 310, one or more of the systems described herein may cause, in response to determining that the data complies with the DLP policy, the data-processing application to perform the operation associated with the user input intercepted as part of step 302. For example, causation module 106 may, as part of computing device 202 in FIG. 2, cause data-processing application 212 to perform the operation associated with user input 210 in response to determination module 110 determining that the operation and/or data 214 complies with DLP policy 122.
Causation module 106 may perform step 310 in a variety of ways. In some examples, causation module 106 may cause a data-processing application to perform the operation associated with the user input intercepted at step 302 by sending the same or similar substitute user input to the data-processing application. For example, if an email application is configured to send an email in response to receiving the keyboard command “cmd+return” and the user input intercepted at step 302 was the command “cmd+return,” causation module 106 may cause the email application to send the email in the manner originally requested by a user by sending the command “cmd+return” to the email application. Additionally or alternative, causation module 106 may cause a data-processing application to perform the operation associated with the user input intercepted at step 302 by instructing the data-processing application to perform the operation via an API of the data-processing application. Upon completion of step 310 in FIG. 3, exemplary method 300 may terminate.
While FIG. 3 represents examples of a system and/or method in which data complies with a DLP policy, FIG. 6 represents examples of a system and/or method in which data does not comply with a DLP policy. FIG. 6 is an additional flow diagram of an exemplary computer-implemented method 600 for capturing input from users to prevent data loss. The steps shown in FIG. 6 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 6 may be performed by one or more of the components of system 100 in FIG. 1, system 200 in FIG. 2, system 400 in FIG. 4, system 500 in FIG. 5, computing system 710 in FIG. 7, and/or portions of exemplary network architecture 800 in FIG. 8.
As illustrated in FIG. 6, at step 602, one or more of the systems described herein may intercept, as part of a DLP application, user input intended for a data-processing application that would, if received by the data-processing application, cause the data-processing application to perform an operation on data that may violate a DLP policy. For example, interception module 104 may, as part of DLP application 208 running on computing device 202 in FIG. 2, intercept user input 210 intended for data-processing application 212 that would, if received by data-processing application 212, cause data-processing application 212 to perform an operation on data 214 that may violate DLP policy 122. Step 602 is similar to step 302 in FIG. 3, therefore, the discussion of step 302 may also apply to step 602.
At step 604, one or more of the systems described herein may cause, upon intercepting the user input, the data-processing application to perform an alternative operation on the data that makes the data accessible to the DLP application. For example, causation module 106 may, as part of computing device 202 in FIG. 2, cause data-processing application 212 to perform an alternative operation on data 214 that makes data 214 accessible to DLP application 208. Step 604 is similar to step 304 in FIG. 3, therefore, the discussion of step 304 may also apply to step 604.
At step 606, one or more of the systems described herein may, while the data-processing application is prevented from performing the operation, scan the data for compliance with the DLP policy. For example, scanning module 108 may, as part of computing device 202 in FIG. 2, scan data 214 for compliance with DLP policy 122 while data-processing application 212 is prevented from performing the operation. Step 606 is similar to step 306 in FIG. 3, therefore, the discussion of step 306 may also apply to step 606.
At step 608, one or more of the systems described herein may determine, based on a result of the scanning performed at step 306, that the data does not comply with the DLP policy. For example, determination module 110 may, as part of computing device 202 in FIG. 2, determine that data 214 does not comply with DLP policy 122.
Determination module 110 may determine that data does not comply with a DLP policy in a variety of ways. In some examples, determination module 110 may determine that data does not comply with a DLP policy if the data includes certain content. For example, determination module 110 may determine that the data does not comply with the DLP policy if the data includes specific words and/or phrases designated as sensitive in the DLP policy. Additionally or alternatively, determination module 110 may determine that the data does not comply with the DLP policy if the DLP policy designates an intended location indicated in the data as unauthorized. Additionally or alternatively, determination module 110 may determine that the data does not comply with the DLP policy if the DLP policy designates an intended recipient indicated in the data as unauthorized.
At step 610, one or more of the systems described herein may initiate, in response to determining that the data does not comply with the DLP policy, a DLP action. For example, causation module 106 may, as part of computing device 202 in FIG. 2, initiate a DLP action in response to determination module 110 determining that data 214 does not comply with DLP policy 122.
Causation module 106 may initiate a variety of DLP actions if data does not comply with a DLP policy. For example, causation module 106 may inform a user of data-processing application 212 that data 214 does not comply with DLP policy 122. In one example, causation module 106 may inform the user that the operation will not be performed on data 214. As another example, causation module 106 may inform an administrator of data-processing application 212 that a user has attempted to perform an operation on data 214 that does not comply with DLP policy 122. In one embodiment, causation module 106 may permanently block data-processing application 212 from performing the operation on data 214. Upon completion of step 610 in FIG. 6, exemplary method 600 may terminate.
As discussed above, the disclosed systems and methods may capture user input intended for an application that may, if received by the application, trigger the application to disseminate certain information. By capturing the user input, the disclosed systems and methods may prevent the application from receiving the user input, thereby preventing the intended dissemination. In some examples, the disclosed systems and methods may send alternative input to the application that causes the application to perform an action that makes the information available to the disclosed systems and methods for DLP processing. After capturing the user input, the disclosed systems and methods may analyze the information to determine whether the information includes sensitive data. In some examples, the disclosed systems and methods may cause the application to disseminate the information after determining that the information does not include sensitive data. In additional or alternative examples, the disclosed systems and methods may permanently prevent the application from disseminating the information after determining that the information includes sensitive information. By controlling whether applications receive user input that may trigger information dissemination, the disclosed systems and methods may indirectly control which information is disseminated from the applications.

intercepting, as part of the data-loss-prevention application, additional user input intended for the email application that would, if received by the email application, cause the email application to send an additional email to an additional location designated by the user;
upon intercepting the additional user input, sending the command to the email application to save the additional email to the location accessible to the data-loss-prevention application;
scanning, while the email application is prevented from sending the additional email to the additional location, the additional email for compliance with the data-loss-prevention policy;
determining, based on a result of the scanning, that the additional email does not comply with at least one element of the data-loss-prevention policy; and
initiating a data-loss-prevention action in response to determining that the additional email does not comply with the element of the data-loss-prevention policy.

10. The computer-implemented method of claim 9, wherein the data-loss-prevention action comprises at least one of:
informing a user of the email application that the additional email does not comply with the element of the data-loss-prevention policy;
informing the user that the email will not be sent;
informing an administrator of the email application that the user has attempted to send the additional email and that the additional email that does not comply with the element of the data-loss-prevention policy; and
permanently blocking the email application from sending the additional email to the additional location.

11. The computer-implemented method of claim 9, wherein determining that the additional email does not comply with the element of the data-loss-prevention policy comprises determining that the email includes at least one of words or phrases designated as sensitive in the data-loss-prevention policy.

12. The computer-implemented method of claim 9, wherein determining that the additional email does not comply with the element of the data-loss-prevention policy comprises determining that at least one of the additional location designated by the user is unauthorized or an intended recipient of the email is unauthorized.

13. A system for capturing input from users to prevent data loss, the system comprising:
an interception module, stored in memory, that intercepts, as part of a data-loss-prevention application, user input intended for an email application that would, if received by the email application, cause the email application to send an email to a location designated by a user of the email application, wherein:
sending the email to the location designated by the user may violate a data-loss-prevention policy;
the data-loss-prevention application is separate and distinct from the email application;

a causation module, stored in memory, that, upon the interception module intercepting the user input, sends a command to the email application to save the email to a location accessible to the data-loss-prevention application, wherein the causation module sends the command by sending at least one of a mouse or keyboard event that is associated with a save command of the email application;
a scanning module, stored in memory, that scans, while the email application is prevented from sending the email to the location designated by the user, the email for compliance with the data-loss-prevention policy;
a determination module, stored in memory, that determines, based on a result of the scanning, that the email complies with the data-loss-prevention policy;
wherein the causation module sends, in response to the determination module determining that the email complies with the data-loss-prevention policy, an additional command to the email application to send the email to the location designated by the user; and
at least one physical processor configured to execute the interception module, the causation module, the scanning module, and the determination module.

14. The system of claim 13, wherein the interception module intercepts the user input intended for the email application by intercepting, as part of the data-loss-prevention application, a keyboard event intended for the email application that would, if received by the email application, cause the email application to send the email to the location designated by the user.

15. The system of claim 14, wherein the keyboard event intended for the email application comprises the command cmd+return.

16. The system of claim 13, wherein the interception module intercepts the user input by intercepting the user input in response to determining that the email application does not support add-ins capable of performing at least one of capturing outgoing email data or preventing send operations.

17. The system of claim 13, wherein the interception module intercepts the user input by temporarily preventing the email application from sending the email to the location designated by the user.

18. The system of claim 13, wherein the causation module sends the additional command to the email application to send the email to the location designated by the user by instructing the email application via an application programming interface.

19. The system of claim 13, wherein the interception module intercepts the user input intended for the email application by intercepting, as part of the data-loss-prevention application, a mouse event intended for the email application that would, if received by the email application, cause the email application to send the email to the location designated by the user.

20. A non-transitory computer-readable medium comprising one or more computer-readable instructions that, when executed by at least one processor of a computing device, cause the computing device to:
intercept, as part of a data-loss-prevention application, user input intended for an email application that would, if received by the email application, cause the email application to send an email to a location designated by a user of the email application, wherein:
sending the email to the location designated by the user may violate a data-loss-prevention policy;
the data-loss-prevention application is separate and distinct from the email application;
