What are measures taken to protect against intelligence threats called?

The term that best describes measures taken to protect against intelligence threats is "Defensive Activities." This concept encompasses a wide range of strategies and practices implemented to safeguard sensitive information and operations from espionage, surveillance, or any form of intelligence breach. Defensive activities may involve physical security measures, personnel security protocols, information assurance practices, and various counterintelligence techniques aimed at recognizing and mitigating threats.

Understanding defensive activities is crucial for individuals and organizations engaged in environments where intelligence threats are prevalent. This term encapsulates the proactive stance necessary to defend against attempts at unauthorized access or information exploitation.

Countermeasures, while closely related, typically refer to specific actions taken in response to a known threat rather than the broader framework of protective measures. Surveillance techniques are methods used for monitoring and gathering information, not protective measures against intelligence threats. Intelligence gathering pertains to the collection of information for strategic purposes, which is fundamentally different from the act of protecting oneself or one’s organization from intelligence risks.
