Episode 15 — Design Retrieval-Augmented Generation That Resists Abuse and Data Spillover

This episode teaches retrieval-augmented generation as a security architecture pattern, because SecAI+ frequently frames scenarios where an LLM is connected to enterprise knowledge and the primary risk becomes what the system retrieves, what it trusts, and what it reveals. You will learn how RAG pipelines typically work, including query formation, vector or hybrid retrieval, ranking, context assembly, and response generation, and why each stage needs explicit guardrails. We will explore abuse patterns such as prompt injection inside retrieved documents, malicious content designed to override instructions, and data spillover where the model includes unrelated sensitive material because retrieval was too broad or authorization checks were weak. You will practice selecting controls that match the failure mode, including strict identity-aware retrieval, least-privilege document access, context window budgeting that prioritizes policy constraints, and safe citation or quoting behavior that limits exposure. We will also cover troubleshooting considerations like diagnosing low-quality answers caused by poor chunking, stale indexes, or over-aggressive filtering, so you can improve reliability without relaxing security boundaries.
