摘要:
A system may be broken down into one or more components. Each of the components may be evaluated to ascribe a security score to each of the components. A composite security score may be generated for the system based on the security scores and a rate of decay measure characterizing a probabilistic security degradation of the system. The rate of decay measure may be applied to the composite security score to obtain a current composite security score. The composite security score may be used to control access to a document, either alone or in addition to other criteria.

Systems and methods described herein may detect hardware modifications. A test loop may terminate at a transmit pin and a receiver pin of a processor footprint pad. A processor may be coupled to the test loop via the transmit pin and the receiver pin. The processor may cause a signal to be transmitted to the test loop from the transmit pin and receive a modified signal from the test loop at the receiver pin. The processor may analyze the modified signal to detect a hardware modification in communication with the test loop based on the modified signal.

A system for autonomous enforcement of rules may comprise a protected system, including infrastructure, operative in response to input signals and an autonomous control system. The autonomous control system may include a monitor circuit which is coupled to the input signals to monitor the input signals for violations of the rules and an action circuit coupled to the protected system which prevents the violating input signals from affecting the protected system.
