Rethinking access control for RAG with Amazon Quick and Amazon Bedrock

This article explains how Amazon Quick and Amazon Bedrock Knowledge Bases solve enterprise RAG security challenges through real-time access control list (ACL) enforcement.

• Traditional replicate-and-filter approaches create security gaps due to stale permissions and incorrect ACL mapping across data sources
• Two-stage architecture combines pre-retrieval ACL filtering with real-time verification against authoritative sources like Google Drive
• Real-time checks verify user permissions directly with source systems at query time, excluding unauthorized documents from LLM context
• Delivers always-current permissions, confidence to scale, and reduced operational burden compared to periodic sync approaches
• Mondelēz International deployed Amazon Quick for 35,000+ employees across four regions with this security model

Real-time ACL enforcement ensures AI responses only include content users are authorized to access, addressing a critical enterprise security requirement.
