Which term is defined as proving a user's identity before granting access?

• A. Authentication
• B. Authorization
• C. Identification
• D. Verification

Answer: (A)

Proving a user's identity before granting access is authentication. Authentication is the process of verifying that the person is who they claim to be, typically by presenting credentials such as something you know (password), something you have (badge or token), or something you are (biometric). Only after successful authentication does the system proceed to determine what the user is allowed to do, which is authorization. Identification, on the other hand, is simply declaring who you are (for example, entering a username) and may lead to verification to confirm that claim. Verification is the act of confirming a claimed identity, which is part of the authentication process. In building automation contexts, authentication ensures that only legitimate users can access control panels, dashboards, or door access, before any permissions are granted.
