摘要

A computer-implemented method for data loss prevention of unidentifiable and unsupported object types may include (1) monitoring, through at least one filter, data input to an application during execution, (2) scanning, through a data loss prevention scanner, the data input to the application to detect whether the data includes sensitive data that is protected by a data loss prevention policy, (3) flagging, based on the scanning, the application as having accessed the sensitive data that is protected by the data loss prevention policy, (4) detecting that the application is requesting to output a data object in a format that obscures underlying content, and (5) performing, by a data loss prevention program, a remedial action to prevent loss of the sensitive data based on both flagging the application and detecting that the application is requesting to output the data object in the format that obscures underlying content.

說(shuō)明書(shū)

At step 310, one or more of the systems described herein may perform, through a data loss prevention program, a remedial action to prevent loss of the sensitive data based on both flagging the application and detecting that the application is requesting to output the data object in the format that obscures underlying content. For example, performance module 112 may, as part of server 206 in FIG. 2, perform, as part of system 200, a remedial action to prevent loss of sensitive data 234 based on both flagging application 230 and detecting that application 230 is requesting to output data object 212 in the format that obscures underlying content. As used herein, the term “remedial action” generally refers to any action that a data loss prevention system may perform to protect sensitive data from loss or leakage.

Performance module 112 may perform the remedial action in a variety of ways. In some examples, performance module 112 may simply block the attempt to output the data object. In these examples, the remedial action may prevent the data object from being received at the corresponding network, file system, and/or operating system clipboard. In further examples, the remedial action may include notifying the application about the blocking of the data object and/or the reason for blocking the data object. In other examples, the remedial action may simply fail the attempt to output the data object without notifying or explaining to the application.
