Focuses largely on protecting the most fundamental critical infrastructures, one of the cornerstones of homeland security. Develops a network theory of vulnerability analysis and risk assessment called “model-based vulnerability analysis,” which is used to extract the critical nodes from each sector and then applying fault and financial risk-reduction techniques to derive the optimal strategy for protection of each sector. At the completion of the course, students should be able to apply the model-based vulnerability technique to any critical infrastructure within their multijurisdictional region, derive optimal strategies, and draft policies for prevention of future terrorist attacks.
