Think of Network Policies in Kubernetes as security checkpoints at different entrances to a building. Just as security personnel at each entrance check IDs and verify permissions before allowing individuals to enter specific areas of the building, Network Policies control the flow of network traffic within the Kubernetes cluster, ensuring that only authorized Pods can communicate with each other and that access to sensitive services is restricted according to defined rules.
