The Defense Information Systems Agency is a United States Department of Defense combat support agency and provides real-time information technology (IT) and communications support to the President, Vice President, Secretary of Defense, the military Services, and the Combatant Commands. From its Arlington, Va., headquarters and through worldwide field activities, DISA offers IT, command and control, communications, and computing services and capabilities that enable our nation's military to accomplish their missions.
DISA is a combat support agency responsible for planning, engineering, acquiring, fielding, and supporting global net-centric solutions to serve the needs of the President, Vice President, the Secretary of Defense, and other DoD Components, under all conditions of peace and war.
The SIPRNet (Secret [formerly Secure] Internet Protocol Router Network) is a system of interconnected computer networks used by the U.S. Department of Defense and the U.S. Department of State to transmit classified information (up to and including information classified SECRET) by packet switching over the TCP/IP protocols in a "completely secure" environment. It also provides services such as hypertext documents and electronic mail. In other words, the SIPRNet is the DoD’s classified version of the civilian Internet together with its counterpart, the Top Secret and SCI Joint Worldwide Intelligence Communications System, JWICS.
NIPRNet (Non-classified Internet Protocol Router Network) (formerly called the Non-secure Internet Protocol Router Network). NIPRNET is used to exchange unclassified but sensitive information between "internal" users as well as providing users access to the Internet. NIPRNet is composed of Internet protocol routers owned by the United States Department of Defense (DOD). It was created by the Defense Information Systems Agency (DISA) to supersede the earlier MILNET.
The Defense Communications Agency (DCA) was established May 12, 1960 by then-Secretary of Defense Thomas S. Gates. Its mission was to manage the Defense Communications System (DCS), a consolidation of the independent long-haul communications functions of the Army, Navy, and Air Force.
In the 1960s, DCA moved to Arlington, Virginia, and took on several major organizations. The Air Force Office of Commercial Communications Management (now the Defense Information Technology Contracting Organization), the White House Signal Agency (now the White House Communications Agency), and the DoD Damage Assessment Center (now the Joint Staff Support Center) all became a part of DCA. DCA also established six regional communications control centers and two area centers for operational control of the DCS.
In the 1970s, DCA subsumed the Minimum Essential Emergency Communications Network and the Military Satellite Communications Systems Office. It also became responsible for engineering and operating the Worldwide Military Command and Control System. In the 1980s, DCA absorbed the Joint Tactical Command, Control, and Communications Agency, improving its ability to manage and enhance the interoperability of command, control, and communications systems. The Joint Interoperability Test Command was formed within DCA to provide interoperability compliance testing and certification.
On June 25, 1991, DCA was renamed DISA to reflect its role in providing total information systems management for DoD. DISA implemented several Defense Management Report Decisions (DMRD), most notably DMRD 918, which created the Defense Information Infrastructure, now known as the Global Information Grid (GIG). DISA consolidated several (148) information processing centers, then operated by the Service Components and Defense Agencies, into 16 Defense megacenters and, within a few years, consolidated them further into five mainframe-processing centers known as Defense Enterprise Computing Centers (DECC) operated by DISA. The Joint Spectrum Center and the Defense Technical Information Center also became part of DISA. Employment peaks at more than 12,000 military and civilian members.
With the onset of the Global War on Terror and Operations Enduring and Iraqi Freedom, DISA has been at the heart of providing the telecommunications and information systems that enable 21st century joint warfighting. The build up for Iraqi Freedom is the largest implementation of telecommunications and information technology in the history of warfare.
DISA, today, is in the forefront of the development of net-centric enterprise services, which will enable information sharing by connecting people and systems that have information with those who need information; development of net-enabled command capabilities, which will revolutionize command and control supporting joint warfighting; providing network services; and providing computing services that support more than 8 million users of more than 1,400 applications, using more than 1.7 petabytes of storage. DISA’s Computing Services is the number-one provider of Defense personnel, payroll, logistics, accounting, and medical records processing.
DISA has been awarded five Joint Meritorious Unit Awards and continues to offer DoD information systems support, taking data services to the forward-deployed warfighter.
The Global Information Grid Bandwidth Expansion (GIG-BE) Program was a major Department of Defense (DOD) net-centric transformational initiative executed by DISA. GIG-BE created a ubiquitous “bandwidth-available” environment to improve national security intelligence, surveillance and reconnaissance, information assurance, as well as command and control. Through GIG-BE, DISA leveraged DOD’s existing end-to-end information transport capabilities, significantly expanding capacity and reliability to select Joint Staff-approved locations worldwide. GIG-BE achieved full operational capacity on Dec. 20, 2005.
