ABSTRACT

Trusted Network Interpretation of the TCSEC (TNI)   [open pdf - 1MB]

Part I of this document provides interpretations of the Department of Defense Trusted Computer System Evaluation Criteria (TCSEC) (DOD-5200.28-STD), for trusted computer/communications network systems. The specific security feature, the assurance requirements, and the rating structure of the TCSEC are extended to networks of computers ranging from isolated local area networks to wide-area internetwork systems. Part II of this document describes a number of additional security services (e.g., communications integrity, denial of service, transmission security) that arise in conjunction with networks. Those services available in specific network offerings, while inappropriate for the rigorous evaluation applied to TCSEC related feature and assurance requirements, may receive qualitative ratings.
