Episode 18 — AuthN/Z for LLM Apps

This episode explores authentication (AuthN) and authorization (AuthZ) for large language model (LLM) applications, highlighting their importance in managing identities and permissions. Authentication verifies that a user or system is who they claim to be, while authorization defines what actions or resources they are allowed to access. For certification readiness, learners must understand the difference between these two concepts, recognize their application in AI contexts, and describe how least privilege is enforced across sessions and scopes. The exam relevance lies in knowing how access control mechanisms secure inference endpoints, APIs, and integrated services in LLM applications.

Practical examples include requiring multi-factor authentication for developer dashboards, implementing fine-grained scopes for plugin or connector access, and enforcing session expiration to reduce token misuse. Troubleshooting scenarios emphasize the dangers of weak AuthN/Z controls, such as broad-scoped tokens enabling privilege escalation or session hijacking. Best practices include centralized identity providers, strong logging of access events, and ongoing monitoring for anomalous patterns. Learners should be prepared to evaluate case studies where inadequate AuthN/Z undermined security, as well as describe exam-ready best practices that align with enterprise standards.
