Dirección Federal de Seguridad

The Dirección Federal de Seguridad (Federal Security Directorate, DFS) was a Mexican intelligence agency. Created in 1947 under Miguel Alemán Valdés with "the duty of preserving the internal stability of Mexico against all forms of subversion and terrorist threats", it was merged into the Centro de Investigación y Seguridad Nacional (CISEN) in 1985 after the murder of the U.S. agent Enrique Camarena Salazar.

According to Peter Dale Scott, "the DFS was in part a CIA creation", and "the CIA's closest government allies were for years in the DFS". DFS badges, "handed out to top-level Mexican drug-traffickers, have been labelled by DEA agents a virtual 'license to traffic'". Scott also said, "The Guadalajara Cartel, Mexico's most powerful drug-trafficking network in the early 1980s, prospered largely because it enjoyed the protection of the DFS, under its chief Miguel Nazar Haro, a CIA asset."

During the period called the dirty war (the Mexican theater of the Cold War), the DFS in conjunction with the Mexican army was responsible for a number of illegal detentions, torture, assassinations and forced disappearances. At least 347 complaints were received by the United Nations related to Mexican State crimes from 1960 to 1980.

Mexican journalist Manuel Buendía Tellezgirón was murdered by members of the DFS for reporting on Mexican high-ranking officials corruption, and their relation with the CIA and Drug Trafficking.
