Rancher RKE2 runtime must enforce ports, protocols, and services that adhere to the PPSM CAL.

Ports, protocols, and services within the RKE2 runtime must be controlled and conform to the PPSM CAL. Those ports, protocols, and services that fall outside the PPSM CAL must be blocked by the runtime. Instructions on the PPSM can be found in DOD Instruction 8551.01 Policy. RKE2 sets most ports and services configuration upon initiation; however, these ports can be changed after the fact to noncompliant configurations. It is important to verify core component configurations for compliance. API Server, Scheduler, Controller, ETCD, and User Pods should all be checked to ensure proper PPS configuration.
