ITPEC IP April 2021 Question 36
ITPEC IP April 2021 — Question 36 of 100
An IC card is possession-based, a password is knowledge-based, and a fingerprint is biometric. The three factors correspond to something the user has, something the user knows, and something the user is. This mapping is shown in option (b).
Answer (b)
Why not others:
- an IC card is carried, not memorized or a physical body characteristic
- an ID and password depend on remembered information
- a fingerprint is an inherent physical characteristic, not an object possessed
Key rule: Authentication factors are commonly classified as possession, knowledge, and inherence.
