Permissions, Security, and Compliance in RAG Pipelines
Blog post from Unified.to
Retrieval-augmented generation (RAG) systems in enterprise environments offer a transformative approach to answering questions by integrating internal content, such as CRM records and support tickets, into prompts. This capability introduces complex challenges around permissions, security, and compliance that are fundamental architectural requirements rather than optional layers. Traditional SaaS applications address permissions at the UI and API levels, but RAG systems must incorporate authorization across ingestion, indexing, retrieval, and generation processes. Key security measures include capturing and maintaining access rules, attaching structured metadata to embedded content, and enforcing tenant isolation to prevent data leakage. Authorization checks can occur before or after query execution, with each method presenting trade-offs between security guarantees and computational demands. Additionally, embeddings, although numeric vectors, require stringent security controls due to the risks they pose, necessitating encryption, access control, and comprehensive audit logging. Ensuring tenant isolation and addressing permission drift are crucial to maintaining compliance and preventing unauthorized access. Ultimately, the success of RAG systems in enterprise settings hinges on robust data governance practices that are integrated from the outset, encompassing everything from capturing permissions at ingestion to logging retrieval provenance, thereby transforming RAG pipelines into comprehensive data governance systems.
