Review system documentation (SSP) and identify the documented management networks as well as the documented client networks. A management network can be defined through physical means or logical means to achieve network separation. Check the network interface to verify the administrative console is on a separate management network interface. If the control plane is set up to only be accessed via a defined management network, this is not a finding. If a management network does not exist or network separation is not established, verify the control plane can only be accessed via trusted approved machines. Review system documentation and obtain a list of approved machines for administrator use. Check the firewall rules on the server. An example command is: firewall-cmd --list-all Check for rules showing that only the trusted and approved machines have access to the ports for the control plane (default is 8443) and REST API interface (default 9443). Below is an example of the output: rich rules: rule family="ipv4" source address="<trusted ip>" forward-port port="8443" protocol="tcp" to-port="80" rule family="ipv4" source address="<trusted ip>" forward-port port="9443" protocol="tcp" to-port="80" If access is not limited using a management network, network separation such as vlans, or a firewall rule, this a finding.
