About secret service

A secret service is a government security agency or intelligence agency concerned with clandestine gathering of intelligence data and conducting covert operations related to national security. The tasks and powers of a secret service can vary greatly from one country to another. For instance, a country may establish a secret service which has some high policing powers but not others. The powers and duties of a government organization may be partly secret and partly not. The person may be said to operate openly at home and secretly abroad, or vice versa. Authoritarian and totalitarian regimes usually operate as police states where a secret service may assume the role of a secret police. In the USA, government agencies usually considered secret services include the Central Intelligence Agency, the Defense Intelligence Agency, the Federal Bureau of Investigation, the National Security Agency, the United States Secret Service and the Drug Enforcement Administration.
