Audit logs on the AIX system must be owned by root.

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.

Check the log files under the audit logging directory have correct 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> total 240 -rw-rw---- 1 root system 0 Feb 23 08:44 bin1 -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 ownership is not "root", this is a finding.

Set the owner of the audit log file to "root". # chown root <auditlog file>
