Set the value of "--authorization-mode" to "Webhook" in KUBELET_SYSTEM_PODS_ARGS variable.

Restart the kubelet service using the following command:

systemctl daemon-reload && systemctl restart kubelet

Check Contents

Run the following command on each Worker Node:
ps -ef | grep kubelet
Verify that the --authorization-mode exists and is set to "Webhook".

If the --authorization-mode argument is not set to "Webhook" or doesn't exist, this is a finding.
