Authorization is the process of determining whether an entity or user is allowed to access a particular resource or perform a specific action within a system or application. In other words, it’s the process of verifying that a user has the necessary permissions to access a particular resource or perform a particular action.

Authorization typically involves checking the identity of the user, as well as their access credentials and permissions, against a set of access control rules. These rules may be defined within the application or system itself, or they may be defined in an external authorization server or policy engine.

Authorization is an important part of security in computer systems and is often used in conjunction with authentication, which is the process of verifying the identity of a user. Together, authentication and authorization ensure that only authorized users are able to access sensitive information and perform critical actions within a system.
