The Office of Tailored Access Operations (TAO ), now Computer Network Operations , and structured as S32 ,[ 1] is a cyber-warfare intelligence-gathering unit of the National Security Agency (NSA).[ 2] It has been active since at least 1998, possibly 1997, but was not named or structured as TAO until "the last days of 2000," according to General Michael Hayden .[ 3] [ 4] [ 5]
TAO identifies, monitors, infiltrates, and gathers intelligence on computer systems being used by entities foreign to the United States.[ 6] [ 7] [ 8] [ 9]
