Kubernetes Network Policies: Complete Guide to Pod-Level Security
Kubernetes Network Policies provide a powerful mechanism for controlling traffic flow between pods, namespaces, and external endpoints. By default, Kubernetes allows all pod-to-pod communication, which creates significant security risks in multi-tenant environments. Network Policies enable you to implement micro-segmentation and zero-trust networking principles within your cluster. Understanding and implementing Network …
Policy as Code with Open Policy Agent (OPA)
