LLM Security Reference Architecture

Why it matters

Reference architecture accelerates secure deployment. Understanding shapes production.

The architecture

Frontend: input validation + auth.

Guard layer: input scanning.

Model layer: LLM calls with least privilege.

How it works end to end

Layers: auth → input scan → LLM → output scan → tool authz → audit.

Session isolation per user.

Rate limiting + cost budgets.

Observability: traces + logs + metrics.
