Short Answer 
The answer outlines three steps to identify potential insider threats in individuals like Edward, who shows unusual interest in classified information, excessive curiosity about colleagues’ work, and inconsistent behavior between social interactions and aggressive questioning. Monitoring these behaviors is crucial for assessing security risks.
Step 1: Identify Unusual Interest in Classified Information
Edward displays an *unusual interest* in classified information, particularly through his aggressive inquiries into the sensitive details of his colleagues’ projects. This behavior can be a significant indicator of a potentially dangerous motive, such as accessing and exploiting confidential information. It’s essential to closely observe who shows an inappropriate level of curiosity about classified content.
Step 2: Monitor Excessive Curiosity
His *excessive curiosity* regarding the work of others, especially in the context of maintaining amicable relationships, raises concerns about his motivations. While collaboration is valuable, signs of excessive questioning can imply ulterior motives that jeopardize security. Organizations should watch for behavior that appears to cross the line from professional interest to invasive probing.
Step 3: Assess Inconsistent Behavior
Edward’s *inconsistent behavior*—getting along well with colleagues while simultaneously exhibiting aggressive questioning—can indicate a duality that is typical of insider threats. This split between social engagement and professional actions suggests a potential risk. Monitoring such inconsistencies is vital in evaluating whether this reflects a deeper security concern that needs to be addressed.
