Episode 44 — Control Model Exposure: Endpoints, APIs, Authentication, and Authorization Choices

 This episode explains why exposing a model through endpoints and APIs is a high-impact attack surface, because SecAI+ will test whether you can select authentication, authorization, and traffic controls that prevent misuse, data leakage, and unintended access. You will learn the practical differences between internal-only endpoints, partner-facing APIs, and public interfaces, and how exposure level changes your threat model and required monitoring. We will cover authentication approaches, including strong identity integration, service-to-service credentials, and short-lived tokens, then connect them to authorization models that enforce least privilege, tenant separation, and purpose-based access for retrieval and tools. You will also explore controls that reduce abuse at the interface, such as rate limiting, input validation, content filtering where appropriate, and safe error handling that avoids revealing internal system details. Troubleshooting topics include diagnosing authorization gaps that surface only under certain prompt flows, preventing token leakage through logs, and designing audit trails that can answer who accessed what, when, and why.
