Authentication and Authorization
Authentication and authorization are two of the most important building blocks in information security. As a developer, you must ensure that only the right people can access your systems and data.
Authentication is the process of confirming a user's identity, like checking a password or scanning a fingerprint.
Authorization decides what actions a user is allowed to perform once their identity is verified, such as reading, editing, or deleting information.
Understanding and correctly implementing these concepts protects your applications from unauthorized access and data breaches, keeping users and systems safe.
Understanding Authentication and Authorization
When you log in to a web application using your username and password, you are performing authentication. The application checks your credentials to confirm that you are who you claim to be. For example, when you sign in to an online banking app, the system asks for your password or a fingerprint scan to prove your identity before granting access.
Authorization, on the other hand, determines what actions or resources an authenticated user is allowed to access. After you log in to the banking app, you might be able to view your account balance but not access administrative functions unless your user role allows it. In a software development context, think of a project management tool where team members can see project tasks, but only project managers can edit or delete them. Even though both types of users are authenticated, their level of authorization is different.
In summary, authentication answers the question, "Who are you?" while authorization answers, "What are you allowed to do?" Both are essential to protect sensitive data and ensure that only the right people have access to the right resources in your applications.
