You can test user isolation in a multi-tenant RAG system by executing a test suite that validates per-user authorization. This includes direct cross-tenant retrieval and filter bypass tests to ensure documents are not leaked across users.

Security testing to prevent data leakage in RAG retrieval must validate per-user authorization and check for filter bypasses. It ensures that relevance-driven retrieval, metadata, and embedding inversion do not expose unauthorized documents across tenants.

A vector store isolation test validates access control by using authenticated sessions and document labels to simulate cross-user queries. It checks if the RAG system successfully blocks direct retrieval, metadata leaks, and embedding inversion attacks.

Yes, you need authenticated sessions and document labels to test RAG authorization. These prerequisites allow the test scripts to accurately simulate different users and verify that access control rules enforce strict tenant isolation.

You should check for direct cross-tenant retrieval, filter bypass, relevance-driven leakage, metadata or citation leaks, and embedding inversion vulnerabilities. Testing these ensures your RAG app enforces strict data privacy and user isolation.

Your RAG system returns documents from another tenant due to a filter bypass or relevance-driven leakage in the retrieval logic. Running an isolation test identifies where per-user authorization fails and prevents unauthorized access.
