API Documentation Security: When Your Docs Expose Your Attack Surface ສຳລັບວິສາຫະກິດລາວ

API documentation — Swagger/OpenAPI specifications, developer portals, Postman collections — is essential for API adoption but also maps your attack surface for potential attackers. Security risks include: publicly accessible documentation exposing internal endpoints, documentation revealing authentication mechanisms and token formats, test credentials or API keys in example requests, deprecated endpoints documented but not decommissioned, and detailed error response examples revealing internal architecture. Testing evaluates whether documentation exposure creates security risks and whether documented endpoints match the actual API surface (undocumented endpoints may lack the security controls applied to documented ones).
