What is the difference between intelligence and counterintelligence in practice?

• A. Intelligence collects information about threats; counterintelligence deters, detects, and thwart intelligence collection by adversaries
• B. Counterintelligence collects information about threats
• C. Intelligence lobbies Congress
• D. Counterintelligence is unrelated to intelligence

Answer: (A)

In practice, intelligence is about gathering information on potential threats—who might do what, what capabilities they have, and where weaknesses exist. Counterintelligence is about protecting those information streams and operations from being exploited by adversaries: deterring their attempts to collect information, detecting when such efforts are underway, and thwarting them through security measures, deception, and disruption. So the best description is that intelligence collects information about threats, while counterintelligence actively counteracts the adversary’s information-gathering efforts. For example, if a foreign service tries to recruit someone inside an organization, counterintelligence works to detect and stop that attempt and to strengthen defenses to prevent future breaches.
