Your RAG application might give accurate answers today, but one poisoned document or a single access control mistake could expose confidential data tomorrow!

Welcome to Video 30 of The Techzeen's AI Driven Cyber Security Complete Course 2026.

In this lecture, we explore RAG Security and learn how attackers exploit Retrieval-Augmented Generation (RAG) systems through data poisoning, cross-tenant leakage, and retrieval attacks. You'll also learn how AI Security Engineers protect vector databases, knowledge bases, and retrieval pipelines.

WHAT YOU WILL LEARN

1. What Is RAG Security?
Understand how to protect documents, vector databases, retrieval processes, and LLM context.

2. RAG Data Poisoning
Learn how malicious or manipulated documents can contaminate a knowledge base and influence AI-generated answers.

3. Cross-Tenant Data Leakage
Understand how weak authorization or missing tenant filters can expose one customer's confidential information to another.

4. Retrieval Attacks
Explore how manipulated queries and malicious content can influence which documents enter the LLM's context.

5. Vector Database Security
Learn why authentication, server-side authorization, metadata filtering, and tenant isolation matter.

6. Secure RAG Architecture
Understand document verification, access-controlled retrieval, untrusted-context handling, output validation, and security logging.

YOUR LEARNING OUTCOME
Understand the major security risks in RAG applications and the defensive controls needed to protect the complete pipeline, from document ingestion to retrieval and final AI output.
