"The Department of Homeland Security is responsible for protecting our Nation's critical infrastructure from physical and cyber threats. Cyberspace has united once distinct information infrastructures, including our business and government operations, our emergency preparedness communications, and our critical digital and process control systems and infrastructures. Protection of these systems is essential to the resilience and reliability of the Nation's critical infrastructures and key resources and, therefore, to our economic and national security."
