What does IAM (Identity and Access Management) mean?

A system that manages user identities, roles, and access — for example Keycloak or Azure Entra — separate from the application's business logic.

Noumena deliberately keeps roles (bags of functional rights) and data scopes in the IAM, so user management is decoupled from the protocol code. Onboarding, offboarding, and role changes happen in the IAM without touching the running system.
