Which of the following is considered an anomalous behavior within the Cyber pillar?

Anomalous behavior within the Cyber pillar refers to actions or activities that deviate from the norm and could indicate potential security threats or insider threats. Password changes, when they occur unexpectedly or outside of the normal routine, can signal various issues such as account compromise, unauthorized access attempts, or an insider threat attempting to cover their tracks.

While password changes are a standard security measure, in the context of monitoring for anomalous behavior, they might stand out as suspicious if, for example, an employee changes their password multiple times in a short span or if changes occur shortly after a security incident.

In contrast, daily system use logs, routine software updates, and scheduled system maintenance are typically regular activities that do not reflect unusual behavior. They represent necessary and expected actions within the operational framework of an IT environment. Thus, they would not be classified as anomalous.
