U.S. Department of Homeland Security. (2007). National Strategy for Homeland Security.
The National Strategy for Homeland Security provides a common framework for all preparedness efforts based on four goals: prevent and disrupt terrorist attacks; protect the American people, our critical infrastructure, and key resources; respond to and recover from incidents that do occur; and continue to strengthen the foundation to ensure our long-term success. The strategy also acknowledges the importance of preparing for natural and man-made disasters not caused by terrorism due to their potential impacts on homeland security.
