National Policy on Certification and Accreditation of National Security Telecommunications and Information Systems (CNSS Policy (CNSSP) No. 6) (Oct. 2005) (full-text).
The national security community, in order to ensure the security of National Security Systems, was developing cost-effective policies, procedures, and methodologies for the certification and accreditation (C&A) of national telecommunications and information systems. This C&A policy for National Security Systems will begin to provide the community with standard methodologies for C&A processes, assign authority and responsibilities, and lay a basis for mutual recognition of certification results.
This policy supersedes NSTISSP Policy No. 6, "National Policy on Certification and Accreditation of National Security Telecommunications and Information Systems," dated April 8, 1994.
