What problem does it solve? Operational systems are breached through misconfigured pipelines, over-privileged containers, and APIs that trust client-supplied object IDs. This Skill provides a defensive reference that tells you how to detect and prevent those misconfigurations at each operational layer, without ever describing how to exploit them. ## Core Features & Use Cases - DevSecOps Hardening: Pin pipeline actions, scope pipeline tokens, run secret scanning over full git history, and gate IaC changes on misconfiguration scans before apply. - Container and Kubernetes Defense: Enforce a hardened-pod baseline (non-root, read-only root, dropped capabilities, seccomp), least-privilege RBAC, image scanning with admission control, and runtime threat detection. - API Operational Defense: Enforce server-side object-level authorization against BOLA, rate limits and request-size caps at the gateway, WAF tuning, and GraphQL/REST depth and complexity limits. - Use Case: Before shipping a new service, use this Skill to verify the pipeline scans secrets and IaC, the container runs non-root with a seccomp profile, no ServiceAccount is bound to cluster-admin, and every API endpoint enforces server-side ownership checks. ## Quick Start Review my Kubernetes deployment manifests and API gateway configuration against the operational security checklist and flag any P0 or P1 findings.
