Amazon adds real-time ACL verification to Quick and Bedrock Knowledge Bases for RAG

KEY POINTS
- Amazon implemented a two-stage access-control approach for Amazon Quick and Amazon Bedrock Knowledge Bases: pre-retrieval ACL filtering against indexed attributes, followed by real-time verification with authoritative data sources (e.g., Google Drive APIs using service-account impersonation) to ensure RAG responses respect current permissions.
- This matters because real-time verification reduces the risk of exposing sensitive documents due to stale or incorrectly mapped ACL snapshots while preserving search performance.
