Our Nation’s critical infrastructures consist of the physical and cyber assets of public and private institutions in several sectors: 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. Cyberspace is the nervous system of these infrastructures—the control system of our country. Cyberspace comprises hundreds of thousands of interconnected computers, servers, routers, switches, and fiber optic cables that make our critical infrastructures work. Thus, the healthy functioning of cyberspace is essential to our economy and our national security. Unfortunately, recent events have highlighted the existence of cyberspace vulnerabilities and the fact that malicious actors seek to exploit them.
The document provides a framework for the contributions that we all can make to secure our parts of cyberspace. The paper outlines strategetic objectives to prevent cyber attacks against America’s critical infrastructures, reduce national vulnerability to cyber attacks, and minimize damage and recovery time from cyber attacks that do occur.
