The Assistant Secretary of Defense for Networks & Information Integration (abbreviated ASD(NII)) provides management and oversight of all DoD information technology, including national security systems. The ASD(NII) also serves as the Chief Information Officer (CIO) of the United States Department of Defense (DoD), a position distinct from the ASD and governed by the Clinger-Cohen Act. The ASD(NII)/DoD CIO is the principal staff assistant and advisor to the Secretary of Defense and Deputy Secretary of Defense on networks and network-centric policies and concepts; command, control and communications (C3); non-intelligence space matters; enterprise-wide integration of DoD information matters; Information Technology (IT), including National Security Systems (NSS); information resources management (IRM); spectrum management; network operations; information systems; information assurance (IA); positioning, navigation, and timing (PNT) policy, including airspace and military-air-traffic control activities; sensitive information integration; contingency support and migration planning; and related matters. The ASD(NII)/DoD CIO had responsibilities for integrating information and related activities and services across the Department of Defense. The ASD(NII)/DoD CIO also serves as the DoD Enterprise-level strategist and business adviser from the information, IT, and IRM perspective; Information and IT architect for the DoD enterprise; and, DoD-wide IT and IRM executive. The Director, Defense Information Systems Agency (DISA), reports to the ASD(NII)/DoD CIO. In August 2010, Secretary of Defense Robert Gates announced that the position of ASD(NII) would be eliminated. On January 11, 2012, the position of ASD(NII) was disestablished.〔("Disestablishment of the Assistant Secretary of Defense for Networks and Information Integration (ASD(NII)) and Related Matters" ) Office of Deputy Secretary of Defense. 11 January 2012.〕 == History == This office was previously known as the ''Assistant Secretary of Defense (Command, Control, Communications and Intelligence)'', or ASD(C3I), and was redesignated ASD(NII) in May 2003. ASD(C3I) traces its origins back to the ''Assistant to the Secretary of Defense (Telecommunications)'', an advisory position established in May 1970. A single person held this position before it was replaced in January 1972 by the ''Assistant Secretary of Defense (Telecommunications)'', an office with more weight in the Pentagon bureaucracy. The post was eliminated in January 1974, with responsibilities transferred to the ''Director, Telecommunications and Command and Control Systems under Defense Directive 5135.1''.〔 In March 1977, a new post, the ''Assistant Secretary of Defense (Command, Control, Communications and Intelligence)'', was established by Defense Directive 5137.1, replacing both the ''Director, Telecommunications and Command and Control Systems'' and the ''Assistant Secretary of Defense (Intelligence)/Director of Defense Intelligence''. (The ASD(I) had been established in November 1971, with some functions transferred from the ''Assistant Secretary of Defense (Administration)''. From July 1976 to March 1977, the ASD(I) held the additional designation of ''Director of Defense Intelligence''.)〔 Starting in October 1977, the ASD(C3I) also served as ''Principal Deputy Under Secretary of Defense for Research and Engineering''. In March 1981, the office was retitled ''Deputy Undersecretary of Defense for Communications, Command, Control, and Intelligence'', a position with more bureaucratic weight than that of an assistant secretary. However, the Department of Defense Authorization Act of 1984 (P.L. 98-94), passed in September 1983, mandated the existence of an ASD(C3I). Thus, this post reverted to the title assistant secretary of defense in April 1985 (following Defense Directive 5137.1). The ASD(C3I) was the principal staff officer to Secretary of Defense in his role as executive for the National Communications System. The ASD(C3I) also had responsibilities to oversee the activities of DISA, the Defense Intelligence Agency, and the Defense Security Service.〔 Following Pentagon reorganizations in 2003, the portfolio of ASD(C3I) was transferred to the ASD(NII), the Under Secretary of Defense for Intelligence, the Director of the Defense Intelligence Agency and elsewhere. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Assistant Secretary of Defense for Networks and Information Integration」の詳細全文を読む スポンサード リンク
