The access control system for unattended SCIF entry must use which two concepts such as an access card and PIN?

• A. Authentication, verification
• B. Authorization, auditing
• C. Identification, accountability
• D. Access control, monitoring

Answer: (A)

Proving who someone is before granting access is authentication, and the step that checks that the presented credentials actually match a valid, authorized user is verification. Using an access card (something you have) and a PIN (something you know) provides two pieces of evidence that the person is legitimate, and the system must authenticate that claim and verify the credentials against current access rights. This pairing ensures the unattended SCIF entry remains secure by confirming identity and credential validity. Other concepts like authorization (what you’re allowed to do after identity is proven) or auditing (recording actions) aren’t the immediate proof of who’s at the door, and identification (claiming who you are) lacks the proof step.
