DHS works to enhance the nation’s counter-IED capabilities and reduce the threat of explosive attack against critical infrastructure, the private sector, and federal, state, local, tribal, and territorial entities.
A program to raise public awareness of indicators of terrorism and terrorism-related crime, and to emphasize the importance of reporting suspicious activity to the proper state and local law enforcement authorities.
