The National Infrastructure Simulation and Analysis Center (NISAC) conducts modeling, simulation, and analysis of the nation's critical infrastructure. NISAC analysts assess critical infrastructure risk, vulnerability, interdependencies, and event consequences.
NISAC began as a collaboration between Los Alamos and Sandia National Laboratories in 1999 and was incorporated by the USA Patriot Act of 2001 into the Department of Homeland Security upon its inception in March 2003. The Office of Infrastructure Protection oversees NISAC operations.
NISAC plays a vital role under the National Infrastructure Protection Plan (NIPP), which relies on robust public-private information sharing to protect and build resiliency for the nation's vast infrastructure. The center's multidisciplinary expertise covers the full spectrum of 18 critical infrastructure sectors while focusing on the challenges posed by interdependencies and the consequences of disruption. (See section 6.3.2 of the NIPP.)
NISAC researchers and analysts conduct extensive modeling, simulation, and analysis to support risk mitigation and policy planning. They also provide real-time assistance to Department decisionmakers during such critical incidents as hurricanes, flooding, wildfires, and manmade events.
NISAC analyses help planners prepare for and respond to events that threaten or affect critical infrastructure. Because catastrophic events such as hurricanes and earthquakes do not follow jurisdictional boundaries, NISAC focuses on cross-discipline, cross-jurisdictional preparation and response.
In-depth analyses provide a better understanding of infrastructure disruption impacts and the effectiveness of mitigation strategies. For example, NISAC analyses of possible hurricane consequences greatly aided the Gulf Coast region in preparation and response planning for three hurricanes in 2008.
Analysts also integrate expertise from the center's core partners, their collaborators, and system experts. HITRAC staff serve as customer liaisons to clarify requirements and increase communications between NISAC and study sponsors.
A central resource point for the Department, NISAC's Fast Analysis and Simulation Team (FAST) provides practical information within severe time constraints in response to issues of immediate national importance within severe time constraints. FAST uses NISAC's long-term planning and analysis results, subject matter expertise, and suite of models to rapidly respond to questions on affected sectors, the consequences of infrastructure interdependencies, and potential economic impacts.
HITRAC staff help integrate NISAC analyses into other Department decision processes to increase situational awareness and assure the best possible products within time constraints. Other government agencies also make use of NISAC's analytic skills and technology.
Examples of NISAC's FAST analyses:
U.S./Mexico and U.S./Canada cross-border transportation corridors
Midwest flooding impact
NYC bridges and tunnels
New England water infrastructure
Hurricanes Katrina, Rita, Wilma, Gustav, and Ike: Pre- and post-landfall impacts
