Emni

The Emni was formed in 1975 by merging several separate federal security and intelligence agencies into a single streamlined apparatus. As a state committee, it acts on an inter-agency level, and thus retains a degree of jurisdiction over government ministries and subordinate agencies as far as national security is concerned, including oversight of federal policing, corrections, and customs and border security activities, regularly taking the lead in law enforcement operations with a national scope nominally under republican Ministry of Interior jurisdiction. Its foreign intelligence operations involve setting up clandestine espionage residencies abroad, and recruiting sources working in sensitive positions in target countries' governments or military. Agents are also placed in Arab Union embassies and consulates, where they work under official cover and are protected from arrest by diplomatic immunity. Operatives typically engage in gathering political, economic, and military-strategic information as well as planting disinformation. The agency is also responsible for combatting internal subversion within the country as well as the international Ba'athist movement, maintaining complex public surveillance operations including a vast network of confidential informants at home and abroad. It is active against the Zionist Resistance Front and the Muslim Brotherhood.

The incumbent Chairman of the Joint Security Committee is Ilyas Mosa, in office since 2010.

Name
Upon its establishment, the Joint Security Committee was named as such and referred to exclusively by this name, with staff for the first few years simply referring to it as "the committee" (اللجنة al-lajnah) when not using the official full name; this usage was mostly unambiguous given the context of the agency's work, with other state committees responsible for matters quite separate from intelligence and state security, and thus remains a common colloquialism amongst committee staff.
