Ensure kubelet anonymous authentication is disabled

Cómo se verifica

Método de auditoría: Comando de shell

nodes=$(kubectl get nodes -o jsonpath='{range .items[*]}{.metadata.name}{"\n"}{end}') || exit 1
[ -n "$nodes" ] || exit 1

for n in $nodes; do
  c=$(kubectl get --raw "/api/v1/nodes/$n/proxy/configz") || exit 1
  if ! { printf '%s' "$c" | grep -Eq '"anonymous":\{"enabled":false\}'; }; then echo "noncompliant: $n"; ok=0; fi

if [ "$ok" -eq 1 ]; then echo compliant; fi

Cómo se corrige

Método de corrección: Guía o parche de infraestructura

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.
