The Interagency Security Committee’s (ISC’s) mandate is to enhance the quality and effectiveness of physical security in and the protection of buildings and non-military Federal facilities in the U.S. All non-military federal facilities in the United States will implement ISC standards, regardless if the facility:
- Is government-owned, leased, or managed;
- Will be constructed or modernized; or
- Will be purchased.
ISC standards and best practices can be used to help federal security professionals implement security policies and mandatory standards. The ISC reviews and updates its products on a regular basis. Please be sure you are using the correct version, as some of the previous documents may have been superseded.
