dhs.gov

The Department of Homeland Security (DHS) is a Cabinet department of the United States federal government with one vital mission: to secure the Nation from the many threats we face. This requires the dedication of more than 240,000 employees in jobs that range from aviation and border security to emergency response, from cybersecurity analyst to chemical facility inspector.

The duties of the Department of Homeland Security are wide-ranging, but our goal is clear — keeping America safe:

Mission 1: Prevent Terrorism and Enhance Security
Mission 2: Secure and Manage our Borders
Mission 3: Enforce and Administer our Immigration Laws
Mission 4: Safeguard and Secure Cyberspace
Mission 5: Strengthen National Preparedness and Resilience
Mission 6: Mature and Strengthen Homeland Security

The DHS continually strengthens our partnerships with communities, first responders, law enforcement and government agencies – at the state, local, tribal, federal and international levels. We are accelerating the deployment of science, technology, and innovation in order to make America more secure. And we are becoming leaner, smarter, and more efficient, ensuring that every security resource is used as effectively as possible.

Every day, the dedicated men and women of the Department of Homeland Security bring their range of backgrounds and experiences to the mission of safeguarding the American people, our homeland, and our values. By air, by land, by sea, or in cyberspace, the employees of the DHS work every day to keep our nation safe.
