The vision of homeland security is to ensure a homeland that is safe, secure, and resilient against terrorism and other hazards.
Three key concepts form the foundation of our national homeland security strategy designed to achieve this vision:
Hundreds of thousands of people from across the federal government, state, local, tribal, and territorial governments, the private sector, and other nongovernmental organizations are responsible for executing these missions. These are the people who regularly interact with the public, who are responsible for public safety and security, who own and operate our nation’s critical infrastructures and services, who perform research and develop technology, and who keep watch, prepare for, and respond to emerging threats and disasters. These homeland security professionals must have a clear sense of what it takes to achieve the overarching vision articulated above.
