3b. Counterintelligence is broadly defined as that
intelligence activity, with its resultant informational product,
which is undertaken to protect the security of the nation, and
its personnel and installations abroad, against espionage,
counterespionage, sabotage, and subversion. As an activity,
counterintelligence is the process of procuring, developing,
recording, and disseminating information concerning espionage,
counterespionage, sabotage, and subversion directed against
the national security, and of penetrating, manipulating, or
re ressing individuals, groups, or organizations conducting
o /capable of conducting such acts. Counterintelligence as con-
ducted by Departments and Agencies is defined as all activities,
exclusive of espionage, devoted to destroying the effectiveness
of inimical foreign intelligence activities and to the protection
of information against espionage, personnel against subversion,
and installations or material against sabotage.'
*CIA would prefer to replace "the protection...... sabotage"
with the following wording: "the protection of information,
personnel, installations, and material against espionage, coun-
terespionage, subversion, sabotage, or unauthorized disclosure. "
This version is preferred because information, personnel, etc.,
must each be protected against more than one danger.
(Repeated efforts to interweave the CIA and Army definitions
resulted only in ambiguity and duplication. )
