Implement production-grade Kubernetes security using NetworkPolicies, RBAC, and Pod Security Standards.
This skill provides a comprehensive framework for securing Kubernetes environments through defense-in-depth strategies. It enables developers and DevOps engineers to implement sophisticated NetworkPolicies for traffic isolation, configure granular RBAC for least-privilege access, and apply Pod Security Standards (Privileged, Baseline, Restricted) at the namespace level. By leveraging integrated templates for OPA Gatekeeper and Istio, it helps automate policy enforcement and ensure compliance with industry benchmarks like CIS and NIST, making it indispensable for managing multi-tenant or production-ready clusters.
