We'll learn how to use OPA Gatekeeper to prevent any kind of ingress/egress IP CIDR Ranges.
In this scenario, we have seen how to prevent any kind of ingress/egress access rules and the reason behind using the policies for our organization.
For more info on this scenario - Restrict Ingress IP CIDR Ranges in NetworkPolicies.

This allows us to implement finer controls for the cluster by following the principle of least privilege and making sure that access is given to a particular resource only if it is needed.
