Multifactor Authentication (MFA) is a security approach that requires a user to provide multiple methods of identification to authenticate their identity before gaining access to a system or application. MFA aims to create a layered defense, making it more challenging for unauthorized users to gain…

Test your knowledge of Multifactor Authentication

Question 1

An organization wants to restrict access to certain sensitive files stored on a cloud server. To improve security, which MFA mechanism should be applied?

Correct Answer: Implementing a hardware token and requiring users to enter their token-generated codes

Implementing a hardware token for access fulfills the MFA requirement by adding an additional factor of authentication (something the user has). Other answers either don't add an extra factor or don't address the authentication process.

Question 2

An organization wishes to implement MFA for remote employees who will be accessing the company's network. To ensure both ease of use and strong security, which method could be used?

Correct Answer: Hardware token generating one-time passcodes

Using a hardware token that generates one-time passcodes provides strong security and ease of use, as it requires the employee to have the physical device for access. The other options compromise security or don't fulfill the multi-factor requirement.

Question 3

Your organization recently experienced a data breach, and management has decided to implement Multi-factor Authentication for all employees. A great choice for adding an extra layer of security is:

Correct Answer: Adding biometric authentication, like fingerprint scanners

Multi-factor authentication seeks to strengthen security by requiring multiple unique pieces of evidence ('factors'). Biometric authentication, such as fingerprint scanners, adds another layer of security by requiring some form of physical presence.
