Department Structure
Department Subcomponents and Agencies
Homeland Security leverages resources within federal, state, and
local governments, coordinating the transition of multiple
agencies and programs into a single, integrated agency focused
on protecting the American people and their homeland. More than
87,000 different governmental jurisdictions at the federal,
state, and local level have homeland security responsibilities.
The comprehensive national strategy seeks to develop a
complementary system connecting all levels of government without
duplicating effort. Homeland Security is truly a “national
mission.”
The following list contains the major components that currently
make up the Department of Homeland Security.
