A systems administrator is selecting an authentication system for a data center. The company’s security policy requires that the system support MFA. Which of the following options should the administrator deploy to meet the policy requirements?
A.
A retinal scan and a fingerprint reader
B.
A key fob and an employee badge
C.
An RFID chip and a PIN code
D.
An alphanumeric, case-sensitive password with symbols
Multi-Factor Authentication (MFA) requires the use of two or more different authentication factors to verify a user’s identity. The three main authentication factors are:
Something You Know – Password, PIN, security questions
Something You Have – Smart card, key fob, RFID chip
Something You Are – Biometrics such as fingerprint, retina scan
Option C (RFID chip and PIN code) meets the MFA requirement because:
RFID chip (Something You Have) provides a physical security token.
PIN code (Something You Know) adds a knowledge-based authentication factor.
Other Options:
A. Retinal scan and fingerprint reader: Both are biometric factors (Something You Are) and do not satisfy MFA requirements, which need at least two different categories.
B. Key fob and employee badge: Both are physical items (Something You Have), failing to meet MFA requirements.
D. An alphanumeric, case-sensitive password with symbols: This only represents Something You Know, not MFA.
Thus, RFID chip and PIN code (Option C) provides two separate authentication factors and meets the MFA policy requirements.
