Check: GEN003080

SUSE Linux Enterprise Server v11 for System z STIG: GEN003080 (in versions v1 r12 through v1 r9)

Title

Crontab files must have mode 0600 or less permissive. (Cat II impact)

Discussion

To protect the integrity of scheduled system jobs and prevent malicious modification to these jobs, crontab files must be secured.

Check Content

Check the mode of the crontab files. # ls -lL /etc/crontab /var/spool/cron/ /var/spool/cron/tabs/ If any crontab file has a mode more permissive than 0600, this is a finding.

Fix Text

Change the mode of the crontab files. # chmod 0600 /var/spool/cron/* /etc/cron.d/* /etc/crontab # chmod 0600 /etc/crontab /var/spool/cron/* /var/spool/cron/tabs/*
