What are measures taken to protect against intelligence threats called?

The measures taken to protect against intelligence threats are commonly referred to as "Defensive Activities." This term encompasses a broad array of strategies and actions designed to safeguard information, personnel, and resources from being exploited by foreign intelligence entities or adversaries. Such activities aim to detect, deter, and respond to potential threats, thereby enhancing the security posture of an organization.

Defensive Activities may include risk assessments, training for personnel on identifying intelligence threats, the implementation of secure communication methods, and the establishment of protocols for reporting suspicious activities. The goal is to create a comprehensive defense strategy that mitigates risks and fortifies an organization against intelligence collection efforts.

In contrast, countermeasures generally refer to specific tactics or techniques employed to counteract a particular intelligence operation rather than the overarching strategies that encompass broader defensive actions. Surveillance Techniques relate more to the methods used for monitoring and observing targets rather than protective measures against threats. Intelligence Gathering, while crucial for understanding potential risks, focuses on collecting information rather than safeguarding against threats. Therefore, the term "Defensive Activities" best captures the essence of the protective measures taken against intelligence threats.
