Answer
To indicate unauthorized and forbidden access, isolating security issues from business logic.
HTTP status codes 401 (Unauthorized) and 403 (Forbidden) communicate to clients that access is denied due to authentication or authorization failures. Returning these codes instantly helps to isolate security enforcement from domain logic. In an e-commerce site, an HTTP 401 code might be returned if a user tries to access their account page without logging in, while a 403 might indicate they lack the permissions to access an admin panel.
