What are potential signs of an insider threat?

The choice highlighting unusual behavior, excessive access requests, and unauthorized access attempts accurately represents potential signs of an insider threat. Insider threats can manifest through changes in an individual's normal behavior patterns, particularly when there are access behaviors that deviate from the norm.

Unusual behavior might include erratic work habits, such as working irregular hours or becoming secretive about work. Excessive access requests can signal that an employee is trying to obtain data or resources that are outside their usual scope of work, which can be a red flag for malicious intent or data misuse. Unauthorized access attempts may directly indicate that someone is trying to exploit system vulnerabilities or obtain sensitive information without proper clearance, showcasing a clear risk to organizational security.

In combination, these behaviors can suggest that an employee may not be acting in the best interest of the organization, which is why monitoring for them is critical in maintaining information security and identifying potential insider threats promptly.
