# firewalld
|
|
|
|
Use the `firewalld` 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.

### Installation
|
|
|
|

### Version
|
|
|
|
This resource first became available in v1.40.0 of InSpec.
|
|
|
|
## Syntax
|
|
|
|
describe firewalld do
|
|
it { should be_running }
|
|
its('default_zone') { should eq 'public' }
|
|
it { should have_service_enabled_in_zone('ssh', 'public') }
|
|
it { should have_rule_enabled('family=ipv4 source address=192.168.0.14 accept', 'public') }
|
|
end
|
|
|
|
Use the where clause to test open interfaces, sources, and services in active zones.
|
|
|
|
describe firewalld.where { zone == 'public' } do
|
|
its('interfaces') { should cmp ['enp0s3', 'eno2'] }
|
|
its('sources') { should cmp ['192.168.1.0/24', '192.168.1.2'] }
|
|
its('services') { should cmp ['ssh', 'icmp'] }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Properties

### interfaces
|
|
|
|
The `interfaces` property is used in conjunction with the where class to display open interfaces in an active zone.
|
|
|
|
describe firewalld.where { zone == 'public' } do
|
|
its('interfaces') { should cmp ['enp0s3', 'eno2'] }
|
|
end
|
|
|
|
### sources
|
|
|
|
The `sources` property is used in conjunction with the where class to display open sources in an active zone.
|
|
|
|
describe firewalld.where { zone == 'public' } do
|
|
its('sources') { should cmp ['192.168.1.0/24', '192.168.1.2'] }
|
|
end
|
|
|
|
### services
|
|
|
|
The `services` property is used in conjunction with the where class to display open services in an active zone.
|
|
|
|
describe firewalld.where { zone == 'public' } do
|
|
its('services') { should cmp ['ssh', 'icmp'] }
|
|
end
|
|
|
|
### default_zone
|
|

|
|
For a full list of available matchers, please visit our [matchers page](https://www.inspec.io/docs/reference/matchers/).
|
|
|
|
### `be_installed`
|
|
|
|
The `be_installed` matcher tests if the firewalld service is installed:
|
|
|
|
it { should be_installed }
|
|
|
|
### `be_running`
|
|
|
|
The `be_running` matcher tests if the firewalld service is running:
|
|
|
|
it { should be_running }
|
|
|
|
### `have_zone`
|
|
|
|
`have_zone` returns true or false if the zone is set on firewalld. It does not mean the zone is active.
|
|
|
|
it { should have_zone('public') }
|
|
|
|
### `have_service_enabled_in_zone`
|
|
|
|
`have_service_enabled_in_zone` returns true or false if the service is allowed in the specified zone.
|
|
|
|
it { should have_service_enabled_in_zone('ssh', 'public') }
|
|
|
|
### `have_port_enabled_in_zone`
|
|
|
|
`have_port_enabled_in_zone` returns true or false if the port is allowed in the specified zone.
|
|
|
|
it { should have_port_enabled_in_zone('22/tcp', 'public') }
|
|
|
|
### `have_rule_enabled`
|
|
|
|
`have_rule_enabled` returns true or false if the rich-rule has been specified in the zone.
|
|
|
|
it { should have_rule_enabled('family=ipv4 source address=192.168.0.14 accept', 'public') }
|
|
|
