Critical Infrastructure/Key Resources (CI/KR)
"Critical Infrastructure" is defined by federal law as "systems and assets, whether physical or virtual, so vital to the United States that the incapacity or destruction of such systems and assets would have a debilitating impact on security, national economic security, national public health or safety, or any combination of those matters." The U.S. Department of Homeland Security has identified 18 critical infrastructure sectors, as diverse as agriculture and food, emergency services, and cyber networks.
Critical infrastructure provides enormous benefits, services, and opportunities on which we rely, and the U.S. Department of Homeland Security is very mindful of the risks to this infrastructure posed by terrorists, pandemic diseases and natural disasters. We know that these threats can have serious effects, such as cutting populations off from clean water, power, transportation, or emergency supplies.
