counterintelligence

Definition/Scope: Information gathered and activities conducted to protect against espionage, other intelligence activities, sabotage, or assassinations conducted by or on behalf of foreign governments or elements thereof, foreign organizations, or foreign persons, or international terrorist activities. 2) Activities concerned with identifying and counteracting the security threat posed by hostile intelligence services or organizations, or by individuals engaged in espionage, sabotage, subversion or terrorism. Counterintelligence is the business of identifying and dealing with foreign intelligence threats to the United States. Its core concern is the intelligence services of foreign states and similar organizations of non-state actors, such as transnational terrorist groups. Counterintelligence has both a defensive mission—protecting the nation’s secrets and assets against foreign intelligence penetration—and an offensive mission—finding out what foreign intelligence organizations are planning to better defeat their aims.
