The course helps the student identify key sectors of society known as critical infrastructure. These key sectors are identified as potential targets for those that wish to disrupt our national security. The origins of threats are identified from individuals, groups, or nation states. Critical infrastructure includes electric power supplies, gas and oil, telecommunications, banking and finance, transportation, water supply systems, emergency services, civil defense, food supply, information distribution, military defense, and continuity of government are identified and discussed. The roles of the Department of Homeland Security and national organizations will examine as to how they protect against internal or external threats with relationships to critical infrastructure. Intelligence collection and alert systems created to prevent and warn against infrastructure attacks are also examined.
