Counterterrorism Operations
How U.S. Counterterrorism Works
See how NCTC, FBI, DHS, CIA, NSA and the military divide counterterrorism duties, and how they coordinate under the laws that govern them.
Public Safety
Public safety, in the national security sense, is the work of protecting the country and its people from attacks, disasters, and threats that cross borders. It brings together homeland security, emergency response, border control, and the defense of vital systems such as power grids and computer networks. Federal, state, and local agencies share the work, and the military supports it in limited ways.
