Intelligence can be described as information concerning an enemy or potential enemy, the evaluated conclusions drawn from such information, or an organization/agency engaged in gathering such information. (Merriam-Webster Dictionary)


To delve deeper, intelligence can be describes as the collecting and processing of that information about foreign countries and their agents which is needed by a government for its foreign policy and for national security, the conduct of non-attributable activities abroad to facilitate the implementation of foreign policy, and the protection of both process and product, as well as persons and organizations concerned with these, against unauthorized disclosure--  Bimfort, Martin T.  A Definition of Intelligence.
