Description
Unauthorized disclosure of audit records can reveal system and configuration data to attackers, thus compromising its confidentiality.
Audit information includes all information (e.g., audit records, audit settings, audit reports) needed to successfully audit operating system activity.

ℹ️ Check
Check the log files under the audit logging directory have correct group ownership.
The default log file is /audit/trail.
The log file can be set by the "trail" variable in /etc/security/audit/config.
# grep trail /etc/security/audit/config
trail = /audit/trail
# ls -l <auditlog dir>

-rw-rw---- 1 root system 0 Feb 23 08:44 bin2
-rw-r----- 1 root system 116273 Feb 23 08:44 trail
If any file's group ownership is not "system", this is a finding.
✔️ Fix
Set the group of the audit log file to "system".
# chgrp system <auditlog file>
