This publication has been developed by NIST to further its statutory responsibilities under the Federal Information Security Modernization Act (FISMA), 44 U.S.C. § 3551 et seq., Public Law (P.L.) 113-283. NIST is responsible for developing information security standards and guidelines, including minimum requirements for federal information systems. Such information security standards and guidelines shall not apply to national security systems without the express approval of the appropriate federal officials exercising policy authority over such systems. This guideline is consistent with the requirements of the Office of Management and Budget (OMB) Circular A-130. Nothing in this publication should be taken to contradict the standards and guidelines made mandatory and binding on federal agencies by the Secretary of Commerce under statutory authority. Nor should these guidelines be interpreted as altering or superseding the existing authorities of the Secretary of Commerce, OMB Director, or any other federal official. This publication may be used by nongovernmental organizations on a voluntary basis, and is not subject to copyright in the United States. Attribution would, however, be appreciated by NIST.
