The Civil Security Department (Sinhala: සිවිල් ආරක්ෂක දෙපාර්තමේන්තුව Sivil ārakshaka depathamentuwā; Tamil: சிவில் பாதுகாப்பு துறை) (also known as the CSD) is an auxiliary force administered by the Sri Lankan Ministry of Defence.
It traces its roots to the Home Guards which were lightly armed local volunteers organized to protect their villages from attacks by the LTTE. These units were formed into the National Home Guard Service in 1986 under the Mobilization of Supplementary Force Act No. 40 of 1985. These home-guardsmen came under the command of the local police becoming one of two paramilitary units under the Sri Lanka Police. The Home Guard Service was re-structured on under the Gazette notification No. 1462/20 of 13 September 2006 which established the Civil Security Department (CSD). The CSD is headed by a Director General, currently held by Air Vice Marshal Roshan Biyanwila.
The CSD is not to be confused with the Sri Lanka National Guard, which is a volunteer reserve regiment of the Sri Lanka Army.
