The Islamic Republic features a number of institutions of repression, including especially the IRGC and one of its units with a specific mandate to ensure domestic security, the Basij. All states are concerned about their security, both internationally and domestically. Authoritarian states pay special attention to the domestic dimensions of their security, at times so much so that their security concerns can verge on paranoia. To address these security concerns, states devise a variety of mechanisms and institutions that specialize in surveillance, intelligence gathering, identifying opponents, and, when needed, the threat or actual use of repression against adversaries. In addition to the Revolutionary Guards and the Basij, for domestic security the state also relies on the Security Forces of the Islamic Republic of Iran, or Nirouha-ye Amniyati-e Jomhuri-e Eslami-e Iran, NAJA.
