Agency Mission
The vision of homeland security is to ensure a homeland that is safe, secure, and resilient against terrorism and other hazards where American interests, aspirations, and way of life can thrive.
Three key concepts form the foundation of our national homeland security strategy designed to achieve this vision: Security, Resilience, and Customs and Exchange. In turn, these key concepts drive broad areas of activity that the Quadrennial Homeland Security Review (QHSR) process defines as homeland security missions. These missions are enterprise-wide, and not limited to the Department of Homeland Security. These missions and their associated goals and objectives tell us in detail what it means to prevent, to protect, to respond, and to recover, as well as to build in security, to ensure resilience, and to facilitate customs and exchange.
The Department's vital mission requires the dedication of more than 230,000 employees in jobs that span all our missions:
Mission 1. Preventing Terrorism and Enhancing Security; Mission 2. Securing and Managing Our Borders; Mission 3. Enforcing and Administering Our Immigration Laws; Mission 4. Safeguarding and Securing Cyberspace; Mission 5. Ensuring Resilience to Disasters.
In addition, the Department works to Provide Essential Support to National and Economic Security, and Mature and Strengthen the Homeland Security Enterprise itself.
