The United States Department of Homeland Security (DHS) is a cabinet department of the U.S. federal government with responsibilities in public security, roughly comparable to the interior or home ministries of other countries. Its stated missions involve anti-terrorism, border security, immigration and customs, cyber security, and disaster prevention and management. It was created in November 2002 in response to 9/11 and is the youngest U.S. cabinet department. In fiscal year 2018, it was allocated a net discretionary budget of $47.716 billion. With more than 240,000 employees, DHS is the third largest Cabinet department, after the Departments of Defense and Veterans Affairs.
