The National Strategy to Secure Cyberspace

The nation’s critical infrastructures are composed of public and private institutions in the sectors of agriculture, food, water, public health, emergency services, government, defense industrial base, information and telecommunications, energy, transportation, banking and finance, chemicals and hazardous materials, and postal and shipping. Controlling it all is cyberspace, a composition of hundreds of thousands of interconnected computers, servers, routers, switches, and fiber optic cables that allow the critical infrastructures to work. Thus the healthy functioning of cyberspace is essential to the Untied States economy and national security.
