Which of the following is NOT a method of counterintelligence?

Counterintelligence focuses on protecting an organization's sensitive information and operations from espionage and other intelligence threats. Among the options provided, public awareness campaigns are typically viewed as a proactive measure aimed at educating personnel about security risks and creating a culture of security within the organization. While they play a critical role in fostering awareness and vigilance, they do not fall directly under the traditional methods of counterintelligence, which are more focused on detection, disruption, and the prevention of foreign intelligence activities.

Detection of insider threats involves identifying individuals within an organization who may pose a risk to its security, either intentionally or unintentionally. Gathering foreign intelligence entails collecting information about adversaries that could threaten national or organizational security. Disruption of adversarial actions includes taking steps to thwart or impede hostile efforts against the organization. These methods are integral to the field of counterintelligence, as they directly address threats and aim to protect sensitive data and operations.

Therefore, public awareness campaigns are distinguished from these traditional counterintelligence methods, making this the correct choice.
