Abstract
A security system for vetting run-time operation of device hardware. A model stores vetted states based on device hardware security signals, a severity level value and at least one vetted next state. The vetting system compares each state of the device hardware with the vetted next states of a current state, and provides an indication and a severity level when the real next state does not match a vetted next state. In response to the indication, the synchronization system performs synchronization by comparing each subsequent real next state of the device hardware with the vetted states until initial synchronization occurs when any subsequent real next state matches a vetted state. The learning system receives feedback from the device hardware in response to the indication, and when indicated by the feedback, updates the model in accordance with the feedback.
