Identity and Access Component Diagram

This component diagram presents an authentication service as a set of focused software responsibilities. A client application calls the authentication API, which delegates credential checking and token issuance. Credentials are verified against a user directory. The token service evaluates policy, persists session state and records audit activity. This separation is helpful when teams need to review security boundaries and decide where to add controls such as multi-factor authentication or token revocation. The diagram is not an identity protocol sequence diagram; it shows component dependencies rather than OAuth or OpenID message exchanges. Add an external identity provider when federation is part of the real system.

A solicitação

“An identity and access component diagram with a client application calling an authentication API. The API uses a credential validator and token service; the validator checks a user directory; and the token service uses a policy evaluator, session store and audit component.”

Perguntas frequentes

Dúvidas comuns

Why separate credential validation and token issuance?

They have different responsibilities and may need different security controls or external integrations.

What is the session store for?

It retains server-side session or token state when the chosen authentication model needs it.

Why include auditing?

Authentication events are often needed for monitoring, investigation and compliance.
