Understanding Kubernetes Networking. Part 5: Kubernetes Network Policies intro

In this video, we will discuss Kubernetes network policies which are the primary methods to secure PODs. Without understanding and applying network policies, PODs are vulnerable to malicious network attacks. We will discuss the fundamentals of network policies and go over various demos of restricting ingress and egress access to/from pods by applying out-of-the-box Kubernetes network policies.
