  • Data loss protection through application data access classification
    Patent number: 8695090
    Abstract: A method and apparatus for classifying behavior of an application based on its data access pattern is described. In one embodiment, the method includes monitoring file access events associated with an application, and determining whether at least one of the file access events indicates the application's attempt to manipulate data of a file. If at least one file access event indicates the application's attempt to manipulate the data within the file, then at least one action is caused to be performed.

  • System and method for managing data loss due to policy violations in temporary files
    Patent number: 8671080
    Abstract: A method and apparatus for managing data loss due to policy violations in temporary files is described. In one embodiment, the method includes monitoring, by a client agent, information content on a client for violations of a policy. The method further includes determining, by the client agent, that a violation of the policy has occurred for content of a temporary file of an application.

  • Systems and methods for preventing data loss on external devices
    Patent number: 8224796
    Abstract: A computer-implemented method for data loss prevention may include: 1) indentifying an external device, 2) intercepting a write attempt to a file on the external device, 3) creating a sandbox version of the file, 4) performing the write attempt on the sandbox version of the file, and then 5) analyzing the sandbox version of the file for potential data-loss violations. Various other methods, systems, and computer-readable media are also disclosed.
