Interagency Security Committee

The Interagency Security Committee (ISC) is a collaborative organization that provides leadership to the nonmilitary federal community supporting physical security programs that are comprehensive and risk based.

Creation of the ISC

On October 19, 1995, six months after the Oklahoma City bombing of the Alfred P. Murrah Federal Building, President Clinton issued Executive Order (EO) 12977, creating the ISC to address continuing government-wide security for federal facilities. On November 27, 2023, President Biden signed EO 14111, which supersedes EO 12977, to reinforce the importance of federal facility security in the face of both persistent and emerging threats. 

Mission

• The ISC collaboratively establishes policies, monitors compliance, and enhances the security and protection of federal facilities. 

Vision

• Federal facilities, the people who work at them, and those that visit are safe and secure throughout the country.  

Leadership

Leadership for the ISC is provided by the chair (the Department's Assistant Director for Infrastructure Security), the Chief, ISC, and four standing subcommittees.

• Compliance Subcommittee
• Countermeasures Subcommittee
• Design-Basis Threat Subcommittee
• Standards Subcommittee

Membership

The ISC consists of 24 primary members designated by EO 14111 and, to date, 42 associate members that have subsequently petitioned to join. The ISC provides coordinated interagency solutions to problems, which cannot be solved by individual departments and agencies alone.

• Design-Basis Threat Subcommittee: Provides annual updates to the Design-Basis Threat (DBT) report.
• Standards Subcommittee: The focal point for coordination of all ISC standards.
