From Wikipedia, the free encyclopedia

The Security and Intelligence Division (Abbreviation: SID; simplified Chinese: 安全情报pinyin: Ānquányúqíngbàojú)[1] is an external intelligence agency of the Ministry of Defence of Singapore responsible for gathering and analysing intelligence related to the external security of Singapore.



The Security and Intelligence Division shares a similar background to its domestic counterpart, the Internal Security Department. The primary intelligence organ since the colonial era was the Malaysian Special Branch. With the independence of Singapore, the Ministry of Interior and Defence was directed to reorganize and consolidate all intelligence capabilities in January 1966. SID was subsequently established in February 1966 with Mr Tay Seow Huah being appointed as its first Director.
