Overview Edit

CNSS Logo white New

Under Executive Order 13231, the President redesignated the National Security Telecommunications and Information Systems Security Committee (NSTISSC) as the Committee on National Security Systems (CNSS).

The Department of Defense chairs the Committee under the authorities established by National Security Directive 42 (NSD-42), as amended by Executive Orders (E.O.) 13284 and 13231.

The CNSS provides a forum for the discussion of policy issues, sets national policy, and promulgates direction, operational procedures, and guidance for the security of national security systems.

The Secretary of Defense and the Director of Central Intelligence are responsible for developing and overseeing the implementation of government-wide policies, principles, standards, and guidelines for the security of systems that handle national security information.

Activities Edit

The committee has voting representatives from 21 departments and agencies.[1] In addition, nonvoting observers such as NIST participate in meetings, provide comments and suggestions, and participate in subcommittee and working group activities. The committee organizes its activities by developing an annual program of work and plan of action and milestones. NSA provides logistical and administrative support for the committee, including a Secretariat manager who organizes the day-to-day activities of the committee.

Since its inception, the committee has issued numerous policies, directives, and instructions that are binding upon all federal departments and agencies for national security systems.
