Fix Recommendation

Configure RHEL 10 to allow approved settings and/or running services to comply with the PPSM CLSA for the site or program and the PPSM CAL.

To open a port for a service, configure "firewalld" using the following command:

$ sudo firewall-cmd --permanent --add-port=port_number/tcp
or
$ sudo firewall-cmd --permanent --add-service=service_name

Check Contents

Verify RHEL 10 controls remote access methods by inspecting the firewall configuration.

Inspect the list of enabled firewall ports and verify they are configured correctly by running the following command:

$ sudo firewall-cmd --list-all

Ask the system administrator for the site or program Ports, Protocols, and Services Management Component Local Service Assessment (PPSM CLSA). Verify the services allowed by the firewall match the PPSM CLSA.

If there are additional ports, protocols, or services that are not in the PPSM CLSA, or there are ports, protocols, or services that are prohibited by the PPSM Category Assurance List (CAL), or there are no firewall rules configured, this is a finding.
