US Patent 10002252 Verification of trusted threat-aware microvisor

A trusted threat-aware microvisor may be deployed as a module of a trusted computing base (TCB). The microvisor is illustratively configured to enforce a security policy of the TCB, which may be implemented as a security property of the microvisor. The microvisor may manifest (i.e., demonstrate) the security property in a manner that enforces the security policy. Trustedness denotes a predetermined level of confidence that the security property is demonstrated by the microvisor. The predetermined level of confidence is based on an assurance (i.e., grounds) that the microvisor demonstrates the security property. Trustedness of the microvisor may be verified by subjecting the TCB to enhanced verification analysis configured to ensure that the TCB conforms to an operational model with an appropriate level of confidence over an appropriate range of activity. The operational model may then be configured to analyze conformance of the microvisor to the security property. A combination of conformance by the microvisor to the operational model and to the security property provides assurance (i.e., grounds) for the level of confidence and, thus, verifies trustedness.
