How Amazon Quick and Amazon Bedrock Knowledge Bases perform RAG access control through real-time ACLs
Amazon Quick and Amazon Bedrock Knowledge Bases address the RAG access control challenge through real-time access control list (ACL) access, verifying permissions directly with authoritative sources during queries, avoiding reliance on potentially outdated or incorrectly mapped ACL data. The system employs a two-phase architecture: the first phase performs pre-retrieval filtering, and the second phase calls the data source API in real-time to validate candidate documents, striking a balance between performance and security, ensuring AI responses always comply with the latest permission requirements.
