The Department of Homeland Security has a vital mission: to secure the nation from the many threats we face. This requires the hard work of more than 260,000 employees in jobs that range from aviation and border security to emergency response, from cyber-security analyst to chemical facility inspector.

DOJ also provides grants and training to state, local, and tribal law enforcement partners and brings together national security, counter-terrorism, counterintelligence, and foreign intelligence surveillance operations under a single authority.
