Purpose and Scope

This Regulation implements Executive Order 12958 (reference (e)), "Classified National Security Information," and associated OMB directives within the Department of Defense. It applies to all Components of the Department of Defense. It establishes the Department of Defense Information Security Program to promote proper and effective classification, protection and downgrading of official information requiring protection in the interest of the national security. It also promotes the declassification of information no longer requiring such protection.

There is information, other than classified information, that has been determined to require some type of protection or control. This information is generally known as "controlled unclassified information." Guidance concerning the protection or controls required for such information may be found in a number of DoD Directives, Regulations and Instructions. However, since classified information and controlled unclassified information often exist side-by-side in the work environment, often in the same document, the essence of available guidance pertaining to controlled unclassified information has been captured in Appendix 3 of this Regulation. The purpose of the Appendix is to provide the user, to the extent possible, a single source document for guidance concerning both classified and controlled unclassified
