Which of the following is not considered an anomalous behavior within the Cyber pillar?

Regular password changes are not considered an anomalous behavior within the Cyber pillar. This is because changing passwords is a standard security practice designed to enhance security and protect sensitive information. Regularly updating passwords is often part of organizational policy and helps mitigate the risk of unauthorized access to systems.

In contrast, unauthorized activity, system events, and modifications to folders are behaviors that could signal potential security issues or insider threats. Unauthorized activity may indicate that an individual is accessing or manipulating data they should not be, which is a strong indicator of risk. System events often track unusual behaviors or incidents that deviate from normal operations, highlighting potential vulnerabilities. Modifications to folders can suggest unauthorized changes to critical data structures, which may be indicative of malicious intent or insider threats.

Overall, regular password changes represent a proactive and expected measure in cybersecurity best practices, while the other options reflect actions that can compromise data integrity or security.
