Über dieses E-Book

"This document provides interpretations of the Department of Defense Trusted Computer System Evaluation Criteria (DoD 52O0.28-STD or TCSEC) for computer security subsystems. A computer security subsystem (subsystem) is defined, herein, as hardware, firmware and/or software which can be added to a computer system to enhance the security of the overall system. A subsystem's primary utility is to increase the security of a computer system. The computer system that the subsystem is to protect is referred to as the protected system in this Interpretation. When incorporated into a system environment, evaluated computer security subsystems may be very effective in reducing or eliminating certain types of vulnerabilities whenever entire evaluated systems are unavailable or impractical."--DTIC.
