The General Directorate of Security (Direção-Geral de Segurança) or DGS was a Portuguese criminal police body between 1969 and 1974. Although their duties include, in addition to state security, the supervision of foreigners, border control, and the fight against illegal trafficking of migrants, historically the DGS was essentially a secret police responsible for repression and without judicial control, of all forms of political opposition to the Estado Novo.
