What is a difference between authorization and authentication from an access control perspective?

Authorization defines the author of a specific resource and authentication gives access to the resource itself

Authentication is when the system validates if the user is valid, and authorization enforces and provides resources assigned and required.

Authentication is responsible for accounting access on system resources and the authorization process defines if a user is allowed to author the resource

Authorization tracks if a certain user is authenticated within the system, and authentication is responsible for identifying the authorization method
