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 directory/file permissions include a “+”, this is a finding.
