Trusted Unix Working Group (TRUSIX) Rationale for Selecting Access Control List Features for the Unix System.

摘要

The National Computer Security Center (NCSC) formed the Trusted UNIX Working Group (TRUSIX) in 1987 to provide technical guidance to vendors and evaluators involved in the development of Trusted Computer System Evaluation Criteria (TCSEC) class B3 trusted UNIX* systems. The NCSC specifically targeted the UNIX operating system for this guidance because of its growing popularity among the government and vendor communities. By addressing the class B3 issues, the NCSC believes that this information will also kelp vendors understand how evaluation interpretations will be made at the levels of trust below this class. TRUSIX is making no attempt to address the entire spectrum of technical problems associated with the development of division B systems; rather, the intent is to provide examples of implementations of those security features discernible at the user interface that will be acceptable at this level of trust.
