    What is the major difference between authentication and authorization?

    Authentication is the process of identifying or validating users which is normally done by login and password where as authorization is the process of giving rights and authority to access particular resources and pages.

    As the first process, authentication provides a way of identifying a user, typically by having the user enter a valid user name and valid password before access is granted. The process of authentication is based on each user having a unique set of criteria for gaining access. The AAA server compares a user's authentication credentials with other user credentials stored in a database. If the credentials match, the user is granted access to the network. If the credentials are at variance, authentication fails and network access is denied.

    Following authentication, a user must gain authorization for doing certain tasks. After logging into a system, for instance, the user may try to issue commands. The authorization process determines whether the user has the authority to issue such commands. Simply put, authorization is the process of enforcing policies: determining what types or qualities of activities, resources, or services a user is permitted. Usually, authorization occurs within the context of authentication. Once you have authenticated a user, they may be authorized for different types of access or activity.

    authentication means to verify who are you while you are logging to any account. authorization means you have an access to visit or see a particular page or a thing.

    In my own understanding...

    Authentication is the process to verify / ensure / confirm if a someone or something is real / existing / valid / correct.

    Authorization is giving someone a permission to do something in your behalf.

    What is the major difference between authentication and authorization?

    The ASP.NET authentication scheme that is used to identify users who view an ASP.NET application. An ASP.net application has two separate authentication levels because all requests coming through IIS before it handled by ASP.NET. After IIS authentication schemes ASP.NET implements additional authentication schemes. They are :

    Windows Authentication
    Forms Authentication
    Passport Authentication


    ASP.NET allows two ways to authorize access to a given resources, they are URL authorization and File authorization

    Authentication confirms your identity to grant access to the system. It is the process of validating user credentials to gain user access.

    Authorization determines whether you are authorized to access the resources. It is the process of verifying whether access is allowed or not.

    Authentication refers to the verification of the identity of a subject - is the subject is really who it claims to be? For example, you login to your Web-based Email System by providing your username and password. If they match a username and password combination in the Email System, then the system authenticates you - meaning that it assumes that only you would know your username and password combination and thus you must be the account owner. Hence you are logged in and given access to all your emails.

    Multi-factor authentication means that the system challenges you for multiple inputs and if you pass all of them, only then are you given access. For example, a PIN number may be required to login as well.

    Authorization typically comes after authentication. Authorization is about what permissions have been granted to you in a system. Role-Based Access Control is usually what is implemented for authorization. Each user is given one or more roles. Each role is given one or more permissions. Hence, if you have the Administrator role of your Web Email System, then once you log in, the system will display a menu item to create new users or delete users. However, if you only have a User role, then you will not be allowed to create or delete other users.

    Authentication and authorization might sound similar, but they are distinct security processes in the world of identity and access management (IAM). Authentication confirms that users are who they say they are. Authorization gives those users permission to access a resource.
