AWS Solves RAG Access Control With Real-Time Checks

Enterprise AI systems using Retrieval Augmented Generation face a critical security challenge: ensuring AI-generated answers respect existing document permissions. Common approaches replicate access control lists from sources like SharePoint and Google Drive into an index, but this creates risks from stale permissions, inaccurate mapping, and evolving data source features. Amazon Quick and Amazon Bedrock Knowledge Bases address this with a two-stage hybrid approach: pre-retrieval filtering narrows candidate documents, then real-time API calls verify permissions directly with authoritative sources at query time, ensuring current access controls are always enforced.
