Authorization and authentication are two distinct yet related concepts in computer and information systems security.
Authentication is the process of verifying the identity of a user or entity attempting to access a system or service. The goal of authentication is to ensure that only individuals or entities with valid access credentials are allowed into the system or service. Authentication typically involves the use of a username and password, or other authentication methods such as tokens or digital certificates.
Authorization, on the other hand, is the process of granting specific access rights to a user or entity after they have successfully passed the authentication process. The goal of authorization is to ensure that the user or entity only has access to system or service resources that are appropriate for their level of authority.
