National Infrastructure Simulation and Analysis Center (NISAC)
NISAC was created in 2000 under a program of the Department of Homeland Security’s (DHS) Information Analysis and Infrastructure Protection Directorate. NISAC is a modeling, simulation, and analysis program within DHS comprising program management and outreach personnel in Washington, D.C., and technical staff from Los Alamos National Laboratory (LANL) and Sandia National Laboratories (SNL).
NISAC personnel have examined many sub-systems of the national infrastructure,
including energy, water, telecommunications, transportation, and public health.
NISAC looks at the interdependencies between these systems to understand how
failures in one could disrupt others.
The National Need
America’s critical infrastructures are the foundation for the nation’s economic
and social vitality, national security, and way of life. They frame citizens’
daily lives and support one of the world’s highest living standards.
The nation’s basic, critical infrastructures must be as robust as possible. Regardless of circumstances, these systems must continue to support the health and well-being of the general population while also enabling basic functionality.
Current NISAC Work
Understanding the Nation's Infrastracture
NISAC personnel work to understand the performance of our nation's infrastructures under both usual and unusual conditions, the effects of interdependencies, and the dynamics of their interconnections. We collaborate with a wide variety of subject matter experts to develop better methodologies and tools for characterizing and simulating infrastructure performance.This broad set of capabilities ensures that NISAC is uniquely able to address a broad range of questions related to national infrastructures.
Since its inception, NISAC has gained valuable insight into the vulnerabilities
and failure modes of a broad selection of individual infrastructure sectors/areas.Our
advanced capabilities focus on critical national infrastructures. We provide
comprehensive, quantitative analyses that use a broad characterization of
threats to the nation's infrastructures, including natural and accidental
disasters and malevolent threats.
Predicting Damage from Natural Disasters
We have successfully drawn on our models and simulations to analyze and predict the damage to the nation's critical infrastructures caused by major hurricanes and other disasters. These analysis tools have been used, for example, to understand and mitigate the effects of hurricane landfalls and to predict the impacts of climate change on energy demand and delivery in California.
Assisting Decision Makers
We are ideally positioned to assist decision makers in the areas of policy analysis, investment and mitigation planning, education and training across a broad spectrum of potential threats, and near real-time assistance to crisis response.
