RAG Security: Prevent Data Leaks with Access Control

I've just published a new guide on securing RAG pipelines against data leaks. Originally published on devopsstart.com, this article explores why prompt hardening is not enough and how to implement identity-aware access controls at the data layer. Most security advice for LLM applications focuses on prompt injection, but this is a dangerous misdirection. The most critical and frequently overlooked vulnerability in a Retrieval-Augmented Generation (RAG) pipeline isn't the user's input; it's the un
