What type of behaviors may be seen as a serious insider threat according to reporting standards?

Unexplained personnel disappearance is viewed as a serious insider threat because it raises immediate concerns about the security of sensitive information and the potential for malicious actions. When an employee suddenly goes missing without explanation, it can indicate that they may have left the organization to pursue harmful activities, such as leaking proprietary information or collaborating with external threats. This behavior creates uncertainty and risk within the organization, as the absence of an employee may hinder operations, disrupt team dynamics, and lead to potential security vulnerabilities.

In contrast, behaviors such as increased lunch breaks, attendance at professional development seminars, and social media engagement do not typically raise red flags regarding insider threats. These activities may be seen as normal workplace behavior and do not inherently suggest malicious intent or security risks. Therefore, unexplained personnel disappearance stands out as a significant indicator that necessitates further investigation and caution.
