Title

RHEL 9 cron configuration directories must have a mode of 0700 or less permissive. (Cat II impact)

Discussion

Service configuration files enable or disable features of their respective services that if configured incorrectly can lead to insecure and vulnerable configurations. Therefore, service configuration files should have the correct access rights to prevent unauthorized changes.

Check Content

Verify the permissions of the cron directories with the following command: $ find /etc/cron* -type d | xargs stat -c "%a %n" 700 /etc/cron.d 700 /etc/cron.daily 700 /etc/cron.hourly 700 /etc/cron.monthly 700 /etc/cron.weekly If any cron configuration directory is more permissive than "700", this is a finding.

Fix Text

Configure any RHEL 9 cron configuration directory with a mode more permissive than "0700" as follows: chmod 0700 [cron configuration directory]
