Information
Disable anonymous requests to the API server.
Rationale:
When enabled, requests that are not rejected by other configured authentication methods are treated as anonymous requests. These requests are then served by the API server. You should rely on authentication to authorize access and disallow anonymous requests.
Solution
Edit the `/etc/kubernetes/apiserver` file on the master node and set the `KUBE_API_ARGS` parameter to `'--anonymous-auth=false'`: `KUBE_API_ARGS='--anonymous-auth=false'`
Based on your system, restart the `kube-apiserver` service. For example, `systemctl restart kube-apiserver.service`
Impact:
Anonymous requests will be rejected.
