+Use the `firewalld` Chef InSpec audit resource to test that firewalld is configured to allow and deny access to specific hosts, services, and ports on a system.
 
 A firewalld has a number of zones that can be configured to allow and deny access to specific hosts, services, and ports.

 `have_zone` returns true or false if the zone is set on firewalld. It does not mean the zone is active.

 ### `have_service_enabled_in_zone`

 It is not necessary to add the "rule" string, and you can start with the optional flags that are used in firewalld and end with the action.
