Today I’m going to cover three topics that most people tend to confuse. These terms are often used in conjunction with each other when it comes to security and gaining access to a system. However, these terms are quite different with completely different concepts. These terms are Identification, Authentication, Authorization.
Identification the process by which a subject identifies itself to the access control system.
Authentication is process to validate your credentials such as Username/User ID and password to verify your identity.
Authorization occurs after your identity is successfully authenticated by the system, which therefore gives you some access to resources such as information, files, databases, etc.
