Infrastructure Protection sponsors projects that develop technological solutions for the protection and assurance of defense-critical infrastructure systems vital to national and economic security. Technologies include those to (1) prevent and mitigate threats to computer networks and (2) standardize methodologies and decision aids for the analysis of elements to secure the nation’s infrastructure, including power generation, utilities transmission, water supplies, and health services.
