This publication has been developed by NIST to further its statutory responsibilities under the
Federal Information Security Modernization Act (FISMA) of 2014, 44 U.S.C. § 3551 et seq. ,
Public Law (P.L.) 113- 283. NIST is responsible for developing informat ion security standards and
guidelines, including minimum requirements for federal information systems, but such standards
and guidelines shall not apply to national security systems without the express approval of
appropriate federal officials exercising p olicy 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 bi nding on f ederal 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, Director of the OMB, or any other f ederal officia l. 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.
