## Overview

Kubernetes orchestrates containers at scale — and its powerful defaults are insecure defaults: open dashboards, permissive RBAC, flat pod networking, and secrets in etcd. Securing Kubernetes means hardening the control plane, constraining workloads, segmenting the network, and governing the supply chain of what gets scheduled.

This skill covers the defensive hardening lifecycle: cluster configuration, workload policies, network segmentation, and continuous compliance checking.

Harden in layers from the outside in: control-plane and API access first (it is the keys to everything), then node security, then workload constraints, then network policy. A perfectly configured pod security policy means nothing if the API server is reachable with a stolen over-permissioned kubeconfig.

## When to use

- Provisioning or auditing a Kubernetes cluster (managed or self-hosted).
- Remediating benchmark findings (CIS Kubernetes Benchmark).
- Designing multi-tenant or multi-team cluster isolation.
- Implementing pod security, network policies, and admission control.
