The Office of Tailored Access Operations (TAO) is a cyber-warfare intelligence-gathering unit of the National Security Agency (NSA). It has been active since at least circa 1998. TAO identifies, monitors, infiltrates, and gathers intelligence on computer systems being used by entities foreign to the United States. The NSA terms these activities "computer network exploitation". TAO is reportedly "now the largest and arguably the most important component of the NSA's huge Signal Intelligence (SIGINT) Directorate, consisting of more than 1,000 military and civilian computer hackers, intelligence analysts, targeting specialists, computer hardware and software designers, and electrical engineers."〔 A document leaked by former NSA contractor Edward Snowden describing the unit's work says TAO has software templates allowing it to break into commonly used hardware, including “routers, switches, and firewalls from multiple product vendor lines". According to ''The Washington Post'', TAO engineers prefer to tap networks rather than isolated computers, because there are typically many devices on a single network.〔 ==Physical locations== TAO's headquarters are termed the ''Remote Operations Center'' (ROC) and are based at Fort Meade, Maryland. TAO also has expanded to NSA Hawaii (Wahiawa, Oahu), NSA Georgia (Fort Gordon, Georgia), Texas Cryptologic Center, and Buckley Air Force Base, Denver.〔 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「Tailored Access Operations」の詳細全文を読む スポンサード リンク
