10 Major Differences Between Authentication and Authorization
The terms authentication and authorization are often used interchangeably by most people, still, there are lots of subtle differences between them. Authentication and authorization are excellent ways to secure and protect digital identities, this article highlights the distinctions between then and the individual purposes they serve.
Authentication means confirming your own identity, while authorization means granting access to the system. In simple terms, authentication is the process of verifying who you are, while authorization is the process of verifying what you have access to.
Authentication and Authorization
Both Authentication and Authorization area unit utilized in respect of knowledge security that permits the safety of an automatic data system. Each area unit terribly crucial topics usually related to the online as key items of its service infrastructure.
However, each of the terms area unit terribly completely different from altogether different ideas. whereas it’s true that they’re usually employed in an equivalent context with an equivalent tool, they’re utterly distinct from one another.
In the authentication process, the identity of users is checked for providing access to the system. While in the authorization process, a person’s or user’s authorities are checked for accessing the resources.
The process is done before the authorization process, whereas the authorization process is done after the authentication process.
Authentication
Authentication is about validating your credentials like User Name/User ID and password to verify your identity. The system determines whether you are what you say you are using your credentials. In public and private networks, the system authenticates the user identity via login passwords.
It is usually done by a username and password, and sometimes in conjunction with factors of authentication, which refers to the various ways to be authenticated.
Authentication factors determine the various elements the system uses to verify one’s identity prior to granting him access to anything from accessing a file to requesting a bank transaction.
A user’s identity can be determined by what he knows, what he has, or what he is. When it comes to security, at least two or all three authentication factors must be verified in order to grant someone access to the system.
Authorization
Authorization is a security mechanism to determine access levels or user/client privileges related to system resources including files, services, computer programs, data, and application features. In simpler terms, authorization determines your ability to access the system and up to what extent.
Once your identity is verified by the system after successful authentication, you are then authorized to access the resources of the system.
It is the process of granting or denying access to a network resource. Most computer security systems are based on a two-step process.
The first stage is authentication, which ensures that a user is who he or she claims to be. The second stage is authorization, which allows the user access to various resources based on the user’s identity.
Notable Distinctions between Authentication and Authorization
1. The authentication process determines whether users are who they claim to be while authorization determines what users can and cannot access.
2. Authentication is the first step of authorization so it always comes first. Authorization is done after successful authentication.
3. The authorization process verifies whether access is allowed through policies and rules.
4. Authentication confirms your identity to grant access to the system while authorization determines whether you are authorized to access the resources.
5. A username and password are required for the authentication process and that isn’t necessary for authentication.
