- AI security relies on existing identity and authorization patterns from the API boom.
- Three AI use cases discussed: RAG, tool use (MCP/APIs), and agentic systems.
- RAG requires authorization to filter documents before they reach the LLM.
- Tool use involves controlling AI access to APIs and services via authentication methods like OAuth 2.1.
- Agentic systems need a chain of identity to track human authorization through workflows.
- Deterministic identity enforcement is crucial for probabilistic AI systems.
- FusionAuth examples illustrate implementation with fine-grained authorization and audit logging.
