Committee on National Security Systems Policy

Overview
The Committee on National Security Systems (CNSS) provides a forum for the discussion of policy issues, and is responsible for setting national-level Information Assurance policies, directives, instructions, operational procedures, guidance, and advisories for U.S. Government (USG) departments and agencies for the security of National Security Systems (NSS) through the CNSS Issuance System.

The CNSS is directed to assure the security of NSS against technical exploitation by providing: reliable and continuing assessments of threats and vulnerabilities and implementation of effective countermeasures; a technical base within the USG to achieve this security; and support from the private sector to enhance that technical base assuring that information systems security products are available to secure NSS.
