Abstract
The Nigerian Customs Service (NCS) no doubt occupies a central position in the
maintenance of border and national security, especially in the area of combating smuggling
which remains its principal task as smuggling remains one of the most thriving illegal
industries in Nigeria today. However, NCS perform their duties through intelligence sorting
and cooperation both from within the NCS through the Custom Intelligence Unit (CIU), and
outside the NCS by liaising with other sister agencies and ministries as well as International
communities for intelligence. Moreover, the functional importance of intelligence
considerably calls for the need to properly interrogate and assess the various sources of
intelligence by considering their implications for national security in Nigeria. The paper
therefore examines the various sources of intelligence services, mode of analysis and the
implication on national security. The paper adopted the descriptive design, relied on
secondary sources of data such as relevant books, Internet sources, journal and periodic
articles. It was found that human intelligence (HUMINT) was the major source in use by the
NCS, as it is time consuming, expensive and susceptible to manipulation. The study therefore
concluded that the attention of the NCS should be drawn to the possibilities of deploying
other sources of intelligence such as; images (IMINT), Signal (SGINT), Communication
(COMINT) and electronic (ELINT) which can complement in the short run and possibly
replace HUMINT as sources of intelligence in the long run.
