Vector store and embedding access controls

Access control, input validation, and tenant isolation applied to a RAG pipeline's vector store, the same as any other production data store.

What it does

Applies authentication, authorisation, and per-tenant isolation to a vector store, and validates content before it is indexed, treating it as a first-class data store rather than an implementation detail.

Where it fits

Directly mitigates vector-and-embedding-weaknesses (OWASP LLM08) and reduces the blast radius of a poisoned or leaked knowledge base.

Risks this mitigates

The risks this control addresses, ranked by effectiveness.

Vector and embedding weaknesses

Weaknesses in how vectors and embeddings are generated, stored, or retrieved in a retrieval-augmented generation pipeline let an attacker poison or exfiltrate the knowledge base.
