InformationDo not allow any insecure tokens
Accepting insecure tokens would allow any token without actually authenticating anything. User information is parsed from the token and connections are allowed.
SolutionEdit the `/etc/kubernetes/apiserver` file on the master node and remove the `--insecure-allow-any-token` argument from the `KUBE_API_ARGS` parameter. Based on your system, restart the `kube-apiserver` service. For example: `systemctl restart kube-apiserver.service`
