TheCivil Security Department (Sinhala: සිවිල් ආරක්ෂක දෙපාර්තමේන්තුවSivil ārakshaka depathamentuwā;Tamil: சிவில் பாதுகாப்பு துறை) (also known as theCSD) is anauxiliary force administered by theSri 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 theLTTE. These units were formed into theNational 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 twoparamilitary units under theSri 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 MarshalRoshan Biyanwila.[1]
The CSD is not to be confused with theSri Lanka National Guard, which is a volunteer reserve regiment of theSri Lanka Army.

The original role of the CDS was the protection of "threatened villages" also known as "border villages" that were adjacent to LTTE held areas most of which are inPuttalam,Anuradhapura,Vavuniya,Trincomalee,Polonnaruwa,Ampara andMonaragala Districts. However the role later expanded to protecting important sites and supply routes.[2]
The main roles of the CDS are,
Other, more special duties include:


Starting from the early 1980s, civilians were recruited and armed as territorial defence units. Following the 1982 elections, the state through theMahaweli Authority pursued a policy of forcibly evicting Tamil villagers inWeli Oya andMaduru Oya areas and establishingSinhalese settlements there in order to counterTamil separatism. A 30-member security unit consisting of Sinhalese settlers in Maduru Oya was formed in 1983 with the support of the Mahaweli Authority and theSri Lankan armed forces. The Sinhalese settlers were trained in firearm use and strategic defence. Many of these settlers were later recruited as home guards in the border villages between Sinhalese and Tamil areas.[3] The introduction of the home guards in May 1984 contributed to the escalation of the ethnic conflict, with Tamil civilians being attacked by them and theLTTE launching attacks against Sinhalese settlers in November.[4]
The National Home Guard Service was thus established in 1986 by then Minister of National SecurityLalith Athulathmudali with a strength of about 5000 personnel, armed with12 gaugeshotguns and brown uniforms. No allowances were paid initially, but some rations were issued through co-operative outlets. Subsequent to the takeover by the Police, the volunteers were paid a daily allowance and provided training at Kumbuka camp,Horana.[citation needed]
In 1988 guardswomen were allowed to volunteer, and 1993 saw the first issue of automatic rifles to the Home Guard. However they were not very well organised, trained, or motivated resulting in many villages being massacred by LTTE raids. Further during the 2002 ‘'Ceasefire Agreement" their importance was reduced and were given non-security duties.[2]
In April 2006 due the resumption of the conflict and LTTE raids the then Secretary of Defence, Gotabaya Rajapaksa reformed the organisation renaming it into the Civil Defence Force, followed by the establishment of the Department of Civil Security on 1 January 2007 (throughgazette notification No. 1462/20 of 13 September 2006) to oversee it. The first Director General of the Civil Defence Force was Rear AdmiralSarath Weerasekara.[2]
Functions of the Department of Civil Security were established to be:[1]
The numbers employed increased to 41,500 from just 19,200 and a month-long military training regime under Army and Navy Instructors was introduced. Further, two types of uniforms (similar to military uniforms) were issued to guardsmen. Those in the most vulnerable places were even equipped with night vision equipment. Since then, members of the force have been deployed outside their home villages to maintain public security, including within the capitalColombo. By May 2009 near the end of the war 80% of the Main Supply Routes and 75% of the Forward Defence Lines were guarded by the CDF as well as major religious places such as Sri Maha Bodhiya and Dalada Maligawa as well as crucial economic targets.[2]
Rear Admiral Sarath Weerasekara with the approval of the Defence Secretary formed a special elite unit called ‘Nandimithra' named after one of theTen Giant Warriors. The elite unit consisted of four-man groups from almost all vulnerable villages that were special commando training for ten weeks including ambushes, night fighting, un-armed combat includingAngampora.[2][5] They waited in pathways leading to villages and ambushed LTTE forces that attempted to target villagers and their success deterred terrorist attacks. Unlike the rest of CDF whose duty was to hold off the enemy protecting civilians until reinforcement arrive Nandimithra units launched limited offensives just outside the threatened villages.[2]
In the post-war period, CSD personnel are involved in community service projects, including agriculture, social welfare development, animal husbandry, and construction projects. After 2019 further recruitment was halted to reduce the force in size. As of 2023 the numbers had been reduced to 33,687.[6] It has been proposed to early retire the entire force due to the 20 Billion LKR yearly cost of maintaining it and the lack of duties with many staying home earning salaries.[7]

Training is provided in two stages: basic training is provided by theSri Lankan Army at various army training centres, usually for 2–4 weeks, while periodical training is carried out by mobile training units in the areas where units are deployed.[citation needed]
