The National Security Agency (NSA) is a merger of the National Bureau of Investigation (NBI) which was responsible for covert and overt security investigations, whilst the Executive Action Bureau (EAB) was responsible for carrying out clandestine activities for the Executives.

In 1955, largely as a consequence of an alleged attempt of the life of the president, a series of securities bodies were reorganized or created.

The NSA was left as the only agency solely responsible for gathering national security intelligence, but having to conduct special investigations, whenever the need arises.

Later, on August 30, 1974, the Act creating the National Security Agency (NSA) was published by the Ministry of Foreign Affairs in Monrovia, Liberia.
