Ensure kubelet anonymous authentication is disabled

Kako se proverava

Metod provere: Komanda ljuske

Kako se ispravlja

Metod ispravke: Smernica ili zakrpa infrastrukture

If the audit returns true, the worker node is allowing anonymous requests to the kubelet and should be treated as noncompliant. If the result is null or the field is missing, first confirm the configz response is complete, because Kubernetes identifies that endpoint as the view of the kubelet’s final actuated configuration. Once the result is validated, remediation in EKS should be performed through the supported node provisioning or node update workflow, not by directly editing the kubelet config file on the host. Remediation of new cluster When creating a new EKS cluster or node group, the goal is to ensure worker nodes join the cluster with kubelet anonymous authentication already disabled. This is done by defining the setting in the bootstrap configuration that EKS applies during node creation.
