The Difference Between Authentication and Authorization in a Security Context

When it comes to security, understanding the difference between authentication and authorization is essential. Authentication is the process of verifying the identity of a user. This typically involves a username and password combination, biometric data, or other factors that prove a user is who they claim to be.

On the other hand, authorization is the process of determining what a user is allowed to do once their identity has been verified. This involves defining access levels, permissions, and privileges based on the user's role or group membership.

In summary, while authentication verifies the user's identity, authorization determines what actions the user is permitted to perform.

Understanding the distinction between authentication and authorization is crucial for maintaining a secure environment and preventing unauthorized access to sensitive information.
