GEN000000-SOL00110 - The /etc/security/audit_user file must not have an extended ACL.

Information

Audit_user is a sensitive file that, if compromised, would allow a malicious user to select auditing parameters to ignore their sessions. This would allow malicious operations the auditing subsystem would not detect for that user. It could also result in long-term system compromise possibly leading to the compromise of other systems and networks.

Solution

Remove the extended ACL from the file.
# chmod A- /etc/security/audit_user
