An example of Authorization and Authentication

These days, organizations are rapidly moving towards digital transformation using cloud-based systems. These applications must be protected with strong online security that includes proper authorization and authentication.
For security implementation in your application, Web, Mobile or Back-end, authorization and authentication are used. Let’s dive in to the different scenarios where authorization and authentication are used.

1. What is authentication?
Authentication is the process by which a user is identified using their credentials. The authorization process begins if the certificates are valid. The authorization process will follow the authentication process.
You must prove your identity by providing credentials to access most “things” online. Fortunately, once you have authenticated, many decisions are made seamlessly behind the scenes, thanks to the secret powers and abilities of an administrator.

What is Authorization?
Authorization is the process by which authenticated users are allowed to access resources. It checks whether the user has access rights. Authorization allows you to control access rights by granting and denying specific permissions.
Authorization occurs when the system authenticates your identity. This gives you full access to resources such as files, databases and funds. In simple terms authorization is the ability to access the system. It also determines how much. After authentication is successful, authorization is granted to you to access the system’s resources.
After you authenticate, you will be granted permissions or authorizations to perform certain tasks. Administrators of the system grant permission by using controls. What does it mean to be allowed? One example would be authenticating on your bank website. Authenticating to your bank website will not allow you to access other customers’ accounts or withdraw money from them. Authentication doesn’t grant you “keys to castle”, as you can only access a room within the castle, and not the moat.
2. What is the difference between cookie-based, session-based, and token-based authentication?
A cookie is a string stored in your web browser. It often contains a key that identifies the user on the server. A session is information about an authenticated user on the server that is stored in some way, such as a file or in memory database.
Session-based authentication creates a session when the user logs into the server. The session ID is saved to a cookie on the browser. The cookie is sent along with any subsequent requests, even though the user remains logged in. The cookie can be compared with the session information in the memory by the server to verify the user’s identity.
JSON Web Token (JWT), is a popular alternative to sessions for authentication in web applications. The server creates JWT using a secret in the token-based app and sends it to the client. The client stores the JWT in local storage and includes JWT in every request. The server would then validate the JWT and send the response to the client.

Let’s create an application that authenticates users and show you how to secure your application so that no one can gain access to our resources.
