Prevent Terrorism and Enhance Security

Protecting the American people from terrorist threats is our founding principle and our highest priority. The Department of Homeland Security's counterterrorism responsibilities focus on three goals:

1. Prevent terrorist attacks;
2. Prevent the unauthorized acquisition, importation, movement, or use of chemical, biological, radiological, and nuclear materials and capabilities within the United States; and
3. Reduce the vulnerability of critical infrastructure and key resources, essential leadership, and major events to terrorist attacks and other hazards.
