Authentication and authorization are two fundamental components of information security that are used to safeguard systems and data. Authentication is the method by which a user or service’s identity is confirmed. At the same time, authorization determines what actions or resources a user or service is permitted to access after they have been authenticated.

Authentication involves verifying a user’s identity through a username and password, biometric authentication, or other security measures. It ensures that solely permitted individuals or systems can enter a system. Conversely, authorization entails assigning access permissions to particular resources or actions contingent upon the authenticated identity of a user or service.

The two processes work together to ensure the security of a system. If authentication is compromised, an attacker can get unauthorized system access. If authorization is not correctly configured, even authorized users may be granted excessive access privileges that can lead to data breaches. Thus, it is necessary to comprehend the difference between authentication and authorization and to verify that both are effectively configured to ensure system security.
