Question

Which of the following combines something you know, such as a password, with something you are (a biometric device such as a fingerprint or a retina scan) or something you possess (a smart card or a USB stick)?a. Confidentiality b. Authentication c. Two-factor authentication

Answer 1

Answer:

c. Two-factor authentication

Explanation:

The type of security measure that is being described is known as Two-Factor authentication. This is a security measure in which an individual is only granted access after successfully presenting two or more pieces of evidence to an authentication mechanism. These two forms of evidence can vary from service to service, for example a company may require that the user enter a password and a fingerprint scan, or may ask for a password and SMS code sent to the individual's phone.
