What problem does it solve? Operational security gaps in pipelines, containers, and running APIs let a single misconfiguration cascade into a breach: a leaked pipeline secret, a privileged container, or an API endpoint without server-side authorization. This Skill provides a defensive reference that frames each operational layer as a trust boundary and specifies how to detect, prevent, and verify misconfigurations at each one. ## Core Features & Use Cases - DevSecOps hardening: CI/CD pipeline pinning, least-privilege tokens, ephemeral runners, secret scanning (pre-commit and CI), IaC misconfiguration detection before apply, and SAST/DAST integration. - Container and Kubernetes defense: image scanning and admission control, least-privilege RBAC, container-escape hardening (non-root, read-only root, seccomp, dropped capabilities), and runtime threat detection rules. - API operational defense: OWASP API Top 10 runtime controls including BOLA detection, rate limiting, WAF tuning, and GraphQL/REST depth and complexity limits. - Use Case: Before deploying a new service, use this Skill to audit the pipeline for secret exposure, verify the pod security context meets the hardened baseline, and confirm every API endpoint enforces server-side object-ownership checks. ## Quick Start Review my Kubernetes deployment manifests and CI pipeline configuration against the defensive hardening baselines and list any violations with severity levels.
