What is the difference between authentication and authorization in access control?
- Authentication and authorization are not related to access control.
- Authentication and authorization are the same thing.
- Authentication determines what actions a user is allowed to perform, while authorization verifies their identity.
- Authentication verifies a user's identity, while authorization determines what actions they are allowed to perform.
Authentication is the process of verifying a user's identity, typically through credentials such as passwords, biometric data, or security tokens. Once a user's identity is authenticated, authorization determines what actions they are allowed to perform within the system. In other words, authentication confirms "who you are," while authorization specifies "what you can do." Understanding this distinction is crucial in access control testing to ensure that both authentication and authorization mechanisms are functioning correctly to maintain the security of the system.
