All rsyslog-generated log files must be owned by root. (Cat II impact)

Discussion

The log files generated by rsyslog contain valuable information regarding system configuration, user authentication, and other such information. Log files should be protected from unauthorized access.

Check Content

The owner of all log files written by "rsyslog" should be root. These log files are determined by the second part of each Rule line in "/etc/rsyslog.conf" and typically all appear in "/var/log". To see the owner of a given log file, run the following command: $ ls -l [LOGFILE] Some log files referenced in /etc/rsyslog.conf may be created by other programs and may require exclusion from consideration. If the owner is not root, this is a finding.
