The most recently created department in the U.S. Cabinet that oversees some federal law enforcement agencies is called the Department of Homeland Security (DHS). Established in response to the September 11 attacks in 2001, its mission includes protecting the United States from terrorist attacks, managing border security, enforcing immigration laws, and responding to disasters. It oversees several key agencies such as the Federal Emergency Management Agency (FEMA), the U.S. Customs and Border Protection (CBP), and the U.S. Coast Guard. The Department of Homeland Security is crucial for coordinating national efforts to maintain security and safety across various domains, including cybersecurity and immigration enforcement.
