This is filtering provided at the network edge by a firewall with rules (ACLs) restricting what internal users are allowed to access. Some firewalls have the ability to filter by an application (layer 7 firewalls), but we’re going to concentrate on standard packet-filtering firewalls and their capabilities.

These policies, like any firewall, provide an invaluable means of limiting attack vectors both inside and outside the VPC. It is important to remember that just because an endpoint is behind a firewall doesn’t mean it is not a vulnerability. These suggestions and others are covered in Linux Academy’s Kubernetes Security Course.
