Verify firewalld Enabled

An XCCDF Rule

Description

The firewalld service can be enabled with the following command:

$ sudo systemctl enable firewalld.service

Rationale

Access control methods provide the ability to enhance system security posture by restricting services and known good IP addresses and address ranges. This prevents connections from unknown hosts and protocols.
