Defense Information Systems Agency (DISA)

Defense Information Systems Agency (DISA) is a U.S combat support agency that connects the U.S military and government though IT and communications support.

Originally known as the defense communications industry (DCA), the agency was created in 1960, partially in response to communication issues during WWII. Currently, the DISA serves U.S soldiers globally, allowing them to access crucial information worldwide through services like computer hosting, information assurance, multinational information sharing and data services. DISA’s information systems are used across the full spectrum of military force operations, including offensive tactics, defensive tactics, counterterrorism and humanitarian efforts.

The DISA’s ultimate goal is achieving information dominance by providing an enterprise infrastructure so effective that it gives the user an advantage in combat.
