[1] When the People's Army was founded in February 1948, Military Security Command origins traces its history to the 'safety agency' (Korean: 안전기관) created by the anti-terrorism organization.

During the Korean War, the safety agency worked to find out spies and anti-revolutionary and reactionary elements in the People's Army.

The Military Security Command place more emphasis on secret surveillance such as wiretapping.
