Understanding the Difference Between Authentication and Authorization in a Software System

When it comes to managing access to a software system, it's crucial to differentiate between authentication and authorization. These two terms are often used interchangeably, but they serve distinct purposes:

Authentication

Authentication is the process of verifying the identity of a user or system trying to access the software. It ensures that the individual or entity is who they claim to be. This is typically done through credentials like usernames, passwords, biometrics, or security tokens.

Authorization

Authorization, on the other hand, determines what actions and resources a user or system has permission to access within the software system. It establishes what an authenticated user can or cannot do once their identity has been confirmed. Authorization controls the level of access based on the user's role or privileges.

Key Distinctions

• Authentication: Confirms identity
• Authorization: Grants access based on identity

In summary, authentication validates the user's identity, while authorization determines the level of access granted to that user within the software system. Both processes are essential for maintaining the security and integrity of the system.
