The Department of Homeland Security's first priority is to protect the nation against further terrorist attacks. Component agencies will analyze threats and intelligence, guard our borders and airports, protect our critical infrastructure, and coordinate the response of our nation for future emergencies.
Besides providing a better-coordinated defense of the homeland, DHS is also dedicated to protecting the rights of American citizens and enhancing public services, such as natural disaster assistance and citizenship services, by dedicating offices to these important missions.
In addition to the natural and technological hazards, Americans face threats posed by hostile governments or extremist groups. These threats to national security include acts of terrorism and acts of war. The following links provide more information about how to prepare for national security emergencies.
