Conceptual model · 1 min read

An identity claim must belong to the user

Editorial conceptual model derived from the linked cases and official guidance; not a vendor architecture diagram or an exploitation sequence.

The conceptual model

The identity provider authenticates a subject and binds issued claims to it. The relying application validates the issuer, audience, signature, and ownership binding before mapping to a local account. Failed validation is rejected.
