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>
