Control plane network security
In this section, you will explore two ways in which to protect the control plane of your AKS cluster: Authorized IP ranges and private clusters. You'll start by updating your existing cluster to use authorized IP ranges.
Securing the control plane using authorized IP ranges

In this section, you will configure authorized IP ranges on your existing cluster. You will limit traffic to a random public IP address to verify that traffic blocking works.
