Abstract: A method includes generating a behavioral state for an endpoint device based on actor identities and corresponding subject identities for a plurality of operations wherein for each operation, a respective actor represented by a respective actor identity performs the operation upon a respective subject represented by a respective subject identity. Performance of a later operation by an actor with an actor identity upon a subject with a subject identity is recorded and the actor identity and the subject identity are used to determine that the performance of the later operation does not match the behavioral state and indicates a security risk.

Abstract: An Identity Based Behavior Measurement Architecture (such as the BMA) and related technologies are described herein. In an exemplary embodiment, the BMA can be derived from an IMA and use an identity model to express a deterministic measurement value for platform behavior.
