The National Industrial Security Program, or NISP, is the nominal authority (in the United States) for managing the needs of private industry to access classified information.
Contents
The NISP was established in 1993 by Executive Order 12829. The National Security Council nominally sets policy for the NISP, while the Director of the Information Security Oversight Office is nominally the authority for implementation. Under the ISOO, the Secretary of Defense is nominally the Executive Agent, but the NISP recognizes four different Cognizant Security Agencies, all of which have equal authority: the Department of Defense, the Department of Energy, the Central Intelligence Agency, and the Nuclear Regulatory Commission.
NISP Operating Manual (DoD 5220.22-M)
A major component of the NISP is the NISP Operating Manual, also called NISPOM, or DoD 5220.22-M. The NISPOM establishes the standard procedures and requirements for all government contractors, with regards to classified information. As of 2010, the current NISPOM edition is dated 28 Feb 2006. Chapters and selected sections of this edition are:
Data sanitization
DoD 5220.22-M is sometimes cited as a standard for sanitization to counter data remanence. The NISPOM actually covers the entire field of government–industrial security, of which data sanitization is a very small part (about two paragraphs in a 141-page document). Furthermore, the NISPOM does not actually specify any particular method. Standards for sanitization are left up to the Cognizant Security Authority. The Defense Security Service provides a Clearing and Sanitization Matrix (C&SM) which does specify methods. As of the June 2007 edition of the DSS C&SM, overwriting is no longer acceptable for sanitization of magnetic media; only degaussing or physical destruction is acceptable.
