Which of the following is a common indication of insider threats?

Unauthorized access attempts are indeed a common indication of insider threats. When employees or individuals within an organization try to access information or systems that they are not authorized to use, this behavior can signal malicious intent or efforts to exploit privileged access. Insider threats typically involve someone within the organization who misuses their access for unauthorized purposes, either for personal gain, corporate espionage, or sabotage. Such access attempts can compromise sensitive data and undermine the organization's security posture.

In contrast, frequent system updates are generally a sign of good cybersecurity maintenance, while employees promoting security policies would indicate a culture of awareness and compliance with security practices, both of which are beneficial for the organization. Increased employee turnover may not directly correlate with insider threats but instead could reflect broader organizational issues unrelated to security. These aspects highlight the unique nature of insider threats, making unauthorized access attempts a clear indicator.
