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 scripts in cron job directories.

ls -lL /etc/cron.{d,daily,hourly,monthly,weekly}
If any cron script has a mode more permissive than 0700, this is a finding.

Fix Text

Change the mode of the cron scripts.
# chmod
 go-rwx /etc/cron.d/* /etc/cron.daily/* /etc/cron.hourly/*
/etc/cron.monthly/* /etc/cron.weekly/*
