Interagency Security Committee Standards and Best Practices

The ISC’s mandate is to enhance the quality and effectiveness of physical security in, and the protection of buildings and nonmilitary Federal facilities in the U.S. The ISC standards apply to all nonmilitary Federal facilities in the U.S.—whether government-owned, leased or managed; to be constructed or modernized; or to be purchased.

Government users with a need to know may access the Interagency Security Committee standards that are For Official Use Only (FOUO). To request access, please send an e-mail to ISCAccess@DHS.gov with your full name and contact information including email, the name of your agency, and the reason you need access.

The ISC reviews and updates its products on a regular basis. Please make sure you are using the most updated version as some of our older documents have been superseded.
