Automate service accounts management.
When you create a pod, if you do not specify a service account, it is automatically assigned the default service account in the same namespace. You should create your own service account and let the API server manage its security tokens.
Note
Note
By default, ServiceAccount is set.

Audit

Run the following command on the Control Plane node:
ps -ef | grep kube-apiserver
Verify that the --disable-admission-plugins argument is set to a value that does not includes ServiceAccount.

Remediation

Follow the documentation and create ServiceAccount objects as per your environment. Then, edit the API server pod specification file /etc/kubernetes/manifests/kube-apiserver.yaml on the master node and ensure that the --disable-admission-plugins parameter is set to a value that does not include ServiceAccount.
