DoD 5200.28 (TCSEC)


The Trusted Computer System Evaluation Criteria (TCSEC), otherwise known as the Orange Book, was the United States Department of Defense standard that set basic assessment requirements for security controls built into a computer system. First published in 1983, then updated in 1985, the TCSEC was the centerpiece of the Rainbow Series of DoD security publications. The TCSEC defined four divisions of computer security: D, C, B, and A, where D is minimal protection, C is discretionary protection, B is mandatory protection, and A is verified protection, with C, B, and A containing additional subdivisions, called classes. The TCSEC was canceled by the DoD in 2002, and was replaced by the international Common Criteria standard of 2005.
