For remote network access from outside the network, what is required about authentication methods?

• A. Only One Of The Three Methods Is Used
• B. No Authentication Is Required For Remote Access
• C. At Least Two Of The Three Authentication Methods Must Be Used
• D. Biometric Authentication Is Required For All Remote Access

Answer: (C)

Remote access from outside the network should be protected with multi-factor authentication, using at least two independent factors. The three categories are something you know (password), something you have (token or device), and something you are (biometric). Requiring two of these ensures that compromising one factor (like a password) isn’t enough for access, because the second factor is still needed. That’s why the best rule is to use at least two of the three authentication methods for remote access. Using only one method would be inadequate, and requiring biometric for all remote access is unnecessarily strict and not mandated.
