Differentiate between authentication and authorization in computer security. Give one suitable example of each.
Answer: Authentication is the process of verifying the identity of a user, such as checking a username, password, or one-time password. Authorization is the process of deciding what an authenticated user is allowed to access or perform, such as permitting a teacher to edit marks while allowing a student only to view them.
Solution
Authentication answers the question “Who are you?”, whereas authorization answers “What are you permitted to do?”. Authentication generally occurs before authorization.
