Fix Recommendation

Edit the Kubernetes Kubelet file etc/rancher/rke2/config.yaml on the RKE2 Control Plane and set the following:
--anonymous-auth=false

Once configuration file is updated, restart the RKE2 Agent. Run the command:
systemctl restart rke2-server

Check Contents

Ensure anonymous-auth is set correctly so anonymous requests will be rejected.

Run this command on each node:
/bin/ps -ef | grep kubelet | grep -v grep

If --anonymous-auth is set to "true" or is not configured, this is a finding.
