Context Based Authorized External Device Copy Detection

Abstract:

A system and method monitors access of an external storage device connected to a target device. A notification of a connection of the external storage device to the target device is received, a notification of an external file access on the external storage device is received, and activity of a user on the target device is monitored to detect a user operation accessing a source file stored on the target device. Events are logged based upon the connection, the user operation, and the external file access. Two or more of the events are associated with a copy of the source file to the external connected storage device and the source file history. An alert regarding the association is forwarded to a monitor application in communication with the target device.
