  TL;DR APIs are the control plane of modern cloud-native apps — they expose business logic and data. Secure them by design: apply strong auth & authorization , transport & runtime protections (mTLS, WAF, gateway policies) , rate limiting & quotas , input validation & output encoding , observability (structured logs, traces, metrics) , test-driven security (unit+integration+fuzz) , and CI/CD gates that block risky changes. Use API Gateways, Service Meshes, and automated playbooks to operationalize defenses. Below you’ll find checklists, sample code, CI pipelines, detection recipes, and an incident-response starter. 1. Threat model — what we actually defend against Quick, practical threat categories for cloud-native APIs: Broken authentication / credential theft — leaked API keys, stolen JWTs, weak session management. Broken authorization — IDOR, privilege escalation, horizontal/vertical access bypass. Injection & deserialization — SQL, NoSQL, co...
