Kubernetes Security Policies

概要

Kubernetes Security Policies provides a comprehensive framework for implementing defense-in-depth security within containerized environments. It enables users to enforce network isolation through NetworkPolicies, configure standardized pod security levels, and establish robust RBAC controls to ensure least-privilege access. Beyond basic configuration, the skill offers guidance on advanced security layers like OPA Gatekeeper for admission control, Istio service mesh security, and compliance alignment with CIS Benchmarks, making it an essential tool for hardening production-grade clusters.
