Test and operate APIs
Harden API configuration
Disable unused methods and features, restrict content types and CORS, protect documentation, and keep production errors and credentials controlled.
8 minute lesson
Security misconfiguration can expose a sound codebase. Production deserves its own review.
Inventory gateway, proxy, runtime, framework, storage, and cloud settings. Remove default accounts and sample routes. Keep diagnostics and internal schemas behind the access policy their content requires. Verify TLS across downstream connections too.
Development may expose stack traces, wildcard CORS, and interactive API docs. Copying those defaults into production can bypass careful application code.
Inspect effective runtime behavior because environment variables, gateway rules, and framework defaults may override reviewed files. Save response headers and probe results beside the intended configuration after every production deployment.
Capture effective production settings from the gateway and application, not only configuration files. Probe an unused method, foreign origin, debug route, and downstream plaintext connection, then record the denied result.
