22. The system of claim 13 , wherein the processor is further configured to associate the user intent model with at least one of: a particular user, the operating environment, a network, and a user type.
13. A system for detecting masquerade attacks, the system comprising: a hardware processor that: monitors a first plurality of user actions in a computing environment; monitors files in the computing environment that contain decoy information; generates a user intent model for a category that includes at least one of the first plurality of user actions; monitors a second plurality of user actions; compares 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; determines whether the second plurality of user actions includes accessing the files in the continuing 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; identifies whether the second plurality of user actions is a masquerade attack based at least in part on the comparison; and generates 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.
