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

Description
Kubernetes Controller ports, protocols, and services 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.

Who does this work

5 NICE work roles and 5 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-242412r1043177_chk)

Change to the /etc/kubernetes/manifests/ directory on the Kubernetes Control Plane. Run the command: grep kube-conntroller-manager.manifest -I -secure-port -Review manifest file by executing the following: VIM <Manifest Name>: Review livenessProbe: HttpGet: Port: Review ports: - containerPort: hostPort: - containerPort: hostPort: Run Command: kubectl describe services --all-namespaces Search labels for any controller namespaces. Any manifest and namespace PPS or services configuration not in compliance with PPSM CAL is a finding. Review the information systems documentation and interview the team, gain an understanding of the Controller architecture, and determine applicable PPS. Any PPS in the system documentation not in compliance with the CAL PPSM is a finding. Any PPS not set in the system documentation is a finding. Review findings against the most recent PPSM CAL: https://cyber.mil/ppsm/cal/ Verify Controller network boundary with the PPS associated with the Controller for Assurance Categories. Any PPS not in compliance with the CAL Assurance Category requirements is a finding.

Fix Text (F-45645r1007479_fix)

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