Question
After entering a user ID and password, an online banking user must enter a PIN that was sent as a text message to the user's mobile phone.Which of the following digital security methods is being used?answerSmart cardMultifactor authenticationFirewallDLP
Solution
The digital security method being used in this scenario is Multifactor authentication. Here's why:
-
The user ID and password constitute the first factor of authentication. This is something the user knows.
-
The PIN sent to the user's mobile phone is the second factor. This is something the user has (their phone).
This combination of two different factors (something you know and something you have) is what defines Multifactor authentication.
Smart cards, firewalls, and DLP (Data Loss Prevention) are all different types of security measures, but they do not fit the scenario described.
