Unlike the Defense Intelligence Agency (DIA) and the Central Intelligence Agency (CIA), both of which specialize primarily in foreign human espionage, the NSA has no authority to conduct human-source intelligence gathering, although it is often portrayed doing so in popular culture. Instead, the NSA is entrusted with coordination and deconfliction of SIGINT components of otherwise non-SIGINT government organizations, which are prevented by law from engaging in such activities without the approval of the NSA via the Defense Secretary. As part of these streamlining responsibilities, the agency has a co-located organization called the Central Security Service (CSS), which was created to facilitate cooperation between NSA and other U.S. military cryptanalysis components. Additionally, the NSA Director simultaneously serves as the Commander of the United States Cyber Command and as Chief of the Central Security Service. | Unlike the Defense Intelligence Agency (DIA) and the Central Intelligence Agency (CIA), both of which specialize primarily in foreign human espionage, the NSA has no authority to conduct human-source intelligence gathering, although it is often portrayed doing so in popular culture.
