Final answer:
Authorization is the process that defines the level of access for an authenticated user or service in a computing environment.
Step-by-step explanation:
The process of establishing what level of access an authenticated person or service has is known as Authorization. After a user is identified and authenticated, authorization determines what resources the user is allowed to access and what operations they can perform. This is a critical aspect of security in computing as it enforces access policies and prevents unauthorized use of resources.
