Check Text ( C-36425r2_chk )
Inspect the auditing configuration file, /etc/rc.config.d/auditing, to determine the filename and path of the audit logs. The entries should appear similar to the following:
PRI_AUDFILE=/var/.audit/file1
SEC_AUDFILE=/var/.audit/file2

# egrep “PRI_AUDFILE|SEC_AUDFILE” /etc/rc.config.d/auditing

For each audit log directory/file, check the permissions.
# ls -lLd
# ls -lLa

If any audit log file has permissions greater than 0640 (0750 for directories), this is a finding.
Fix Text (F-31764r2_fix)
As root, change the permissions.
# chmod 0750
# chmod 0640
