Which aspect of counterintelligence focuses on capturing enemy intelligence operations?

The focus on capturing enemy intelligence operations falls under offensive activities. This aspect of counterintelligence involves proactive measures taken to detect and counteract adversarial intelligence efforts. By engaging in offensive activities, organizations or agencies aim to uncover, disrupt, and neutralize the methods and resources the enemy uses to gather intelligence. This might include actions such as conducting surveillance on suspected operatives, infiltrating hostile networks, or preparing countermeasures designed to thwart enemy spying initiatives.

In contrast, other aspects offered in the choices emphasize different strategies. Vigilance pertains to maintaining awareness of potential threats and ensuring that personnel remain alert to signs of espionage or intelligence collection efforts, but it does not actively engage in capturing operations. Defensive strategies focus on protecting sensitive information and infrastructure from intelligence threats through security measures, rather than actively pursuing the enemy's intelligence capabilities. Recruitment efforts target the acquisition of assets within enemy or rival organizations but do not directly involve the actions taken to capture ongoing intelligence operations.
