| Check the permissions of the file. Procedure: Check the configured cron log file found in the cron entry of the rsyslog configuration (normally /var/log/cron). # grep cron /etc/rsyslog.conf /etc/rsyslog.d/*.conf # ls -lL /var/log/cron If the permissions include a '+', the file has an extended ACL. If the file has an extended ACL and it has not been documented with the IAO, this is a finding. |
