Check: GEN003190

SUSE Linux Enterprise Server v11 for System z STIG: GEN003190 (in versions v1 r12 through v1 r9)

Title

The cron log files must not have extended ACLs. (Cat II impact)

Discussion

Cron logs contain reports of scheduled system activities and must be protected from unauthorized access or manipulation.

Check Content

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.

Fix Text

Remove the extended ACL from the file. # setfacl --remove-all /var/log/cron
