Which of the following security techniques is the BEST
method for authenticating a user's identity?
A. Smart card
B. Biometrics
C. Challenge-response token
D. User ID and password
Answer / guest
Answer: B
Biometrics is a security technique that verifies an
individual's identity by analyzing a physical attribute,
which is unique to that individual, e.g. a handprint. Hence,
biometrics ensures that the person who is authorized to
access the system is in actuality the person accessing the
system. Smart card (choice A) is an intelligent credit
card-sized device with a chip. Anybody having the possession
of the smart card and knowing the password can access the
system since the system is unable to know whether the
authorized user is using the smart card or not. A
challenge-response token (choice C) is a method of
authenticating a user, but the system is unable to know
whether the authorized user is using the token or not. User
ID and password (choice D) are things that could be known by
another individual.
