CNTR-K8-000950 - The Kubernetes etcd must enforce ports, protocols, and services (PPS) that adhere to the Ports, Protocols, and Services Management Category Assurance List (PPSM CAL).

Information

Kubernetes etcd PPS must be controlled and conform to the PPSM CAL. Those PPS that fall outside the PPSM CAL must be blocked. Instructions on the PPSM can be found in DoD Instruction 8551.01 Policy.

NOTE: Nessus has not performed this check. Please review the benchmark to ensure target compliance.

Solution

Amend any system documentation requiring revision. Update Kubernetes etcd manifest and namespace PPS configuration to comply with PPSM CAL.
