Internal Security Department, Intelligence agency in Singapore
The Internal Security Department is Singapore's domestic intelligence agency responsible for counterintelligence and threat prevention. It operates within the Ministry of Home Affairs and employs modern surveillance technologies to identify and counter potential dangers to national stability.
Founded in 1966 following Singapore's separation from Malaysia, the agency evolved from the Singapore Special Branch to address new security needs. Its mandate has expanded over decades to respond to evolving domestic and international threats.
The department maintains strict confidentiality protocols, with the identities of its directors remaining undisclosed until they leave their positions.
This agency operates as a government institution not open to public visits or tours due to its security-sensitive nature. Visitors should not expect any public access or interactive experiences at this facility.
During the 1974 Laju incident, the department conducted negotiations with militants who had taken hostages at the Pulau Bukom oil refinery.
