25. A non-transitory computer-readable medium containing, computer-executable instructions that, when executed by a processor, cause the processor to perform a method for detecting masquerade attacks, the method comprising: monitoring a first plurality of user actions in a computing environment; monitoring files in the computing environment that contain decoy information; generating a user intent model for a category that includes at least one of the first plurality of user actions; monitoring a second plurality of user actions; comparing the second plurality of user actions with the generated user intent model by determining whether at least one of the second plurality of user activities deviates from the generated user intent model; determining whether the second plurality of user actions includes accessing the files in the computing environment that contain the decoy information in response to determining that at least one of the second plurality of user actions deviates from the generated user intent model; identifying whether the second plurality of user actions is a masquerade attack based at least in part on the comparison; and generating an alert in response to identifying that the second plurality of user actions is the masquerade attack and in response to determining that the second plurality of user actions includes accessing the files in the computing environment that contain the decoy information.

The non-transitory computer-readable medium of claim 25 , wherein the decoy information includes a beacon, and wherein the method further comprises using a sensor that monitors the beacon in the decoy information to determine whether the decoy information has been accessed.
