Description
It is important to disable any unnecessary components to reduce any potential attack surfaces. RKE2 allows disabling the following components: - rke2-canal - rke2-coredns - rke2-ingress-nginx - rke2-kube-proxy - rke2-metrics-server If using any of these components presents a security risk, or if any of the components are not required, they can be disabled by using the "disable" flag. Satisfies: SRG-APP-000141-CTR-000315, SRG-APP-000384-CTR-000915

Who does this work

8 NICE work roles and 8 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-254565r1208189_chk)

Ensure the RKE2 Server configuration file on all RKE2 Server hosts contains a "disable" flag only if there are default RKE2 components that need to be disabled. If there are no default components that need to be disabled, this is not a finding. Run this command on the RKE2 Control Plane: cat /etc/rancher/rke2/config.yaml RKE2 allows disabling the following components. If any of the components are not required, they can be disabled: - rke2-canal - rke2-coredns - rke2-ingress-nginx - rke2-kube-proxy - rke2-metrics-server If services not in use are enabled, this is a finding.

Fix Text (F-57998r1208188_fix)

Disable unnecessary RKE2 components. Edit the RKE2 Server configuration file on all RKE2 Server hosts, located at /etc/rancher/rke2/config.yaml, so that it contains a "disable" flag if any default RKE2 components are unnecessary. Example: disable: - rke2-canal - rke2-ingress-nginx - rke2-kube-proxy - rke2-metrics-server - rke2-coredns Once the configuration file is updated, restart the RKE2 Server. Run the command: systemctl restart rke2-server
