Verify Permissions on cron.daily

An XCCDF Rule

Description

To properly set the permissions of /etc/cron.daily, run the command:

$ sudo chmod 0700 /etc/cron.daily

Rationale

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.
