Department of Homeland Security (DHS)

"The US Department of Homeland Security exists to keep America safe. Created in the wake of the 9/11 terrorist attacks, the department is devoted to keeping the US safe from natural and man-made disaster. Its activities include domestic nuclear detection, intelligence coordination, and protection of high-level government officials. The department's structure includes agencies for citizenship and immigration services, customs and border protection, emergency response and recovery (FEMA), and science and technology research"

"In the aftermath of September 11 and the knowledge at that time that our immigration system had failed us in not keeping the hijackers out of the country and off our domestic planes, the DHS was created to pull a number of agencies under a national security umbrella."

- Janice Kephart, Director of National Security Policy
