42 U.S. Code § 5195c - Critical infrastructures protection
There shall be established the National Infrastructure Simulation and Analysis Center (NISAC) to serve as a source of national competence to address critical infrastructure protection and continuity through support for activities related to counterterrorism, threat assessment, and risk mitigation.
In this section, the term “critical infrastructure” means systems and assets, whether physical or virtual, so vital to the United States that the incapacity or destruction of such systems and assets would have a debilitating impact on security, national economic security, national public health or safety, or any combination of those matters.
There is hereby authorized for the Department of Defense for fiscal year 2002, $20,000,000 for the Defense Threat Reduction Agency for activities of the National Infrastructure Simulation and Analysis Center under this section in that fiscal year.
Section was enacted as the Critical Infrastructures Protection Act of 2001 and also as part of the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001 or USA PATRIOT Act, and not as part of the Robert T. Stafford Disaster Relief and Emergency Assistance Act which comprises this chapter.
For transfer of functions, personnel, assets, and liabilities of the National Infrastructure Simulation and Analysis Center of the Department of Energy, including the functions of the Secretary of Energy relating thereto, to the Secretary of Homeland Security, and for treatment of related references, see sections 121(g)(4), 551(d), 552(d), and 557 of Title 6, Domestic Security, and the Department of Homeland Security Reorganization Plan of November 25, 2002, as modified, set out as a note under section 542 of Title 6.
