NISAC experts analyze—using modeling and simulation capabilities—critical infrastructure, along with their interdependencies, vulnerabilities, and complexities. Their analyses are used to aid decisionmakers with policy assessment, mitigation planning, education, and training and provide near-real-time assistance to crisis-response organizations.

Infrastructure systems are large, complex, dynamic, adaptive, nonlinear, and behavioral. These systems are too complex for mental models to be effective decision tools. NISAC analysts use models ranging from realistic to abstract, depending on the questions being posed, to gain expert operational insight.

Analysts study the details of individual infrastructure, from the asset level to the system level; interactions between infrastructure; and how critical infrastructure respond to natural disasters, cyber threats, or terrorist attacks. This includes potential economic impacts and how human behavior affects how a situation evolves.

Natural disasters or imposed threats require NISAC analysts to employ their knowledge of different infrastructure along with a variety of capabilities, including modeling and simulation, to provide real-time assistance to decision makers. This integrated analysis strategy is also used for policy assessment, mitigation planning, and assisting crisis-response organizations in preparedness activities.
