After studying for my CKS certification, I found Kubernetes security resources scattered across dozens of sites, often behind paywalls or too surface-level. So I built k8s-security.guru — a free, comprehensive documentation site covering:
- All 6 CKS exam domains (cluster hardening, RBAC, network policies, supply chain security, runtime security)
- 20+ attack vectors with step-by-step exploitation and mitigations
- Tool guides for Falco, Trivy, OPA Gatekeeper, Kyverno, Cosign, and more
- Practice questions for CKS prep
- Searchable glossary of 50+ security terms
Everything is based on official Kubernetes docs, CIS benchmarks, and CNCF project documentation. No ads blocking content, no signup required.

Feedback welcome — happy to add topics if something’s missing.
