Which category of authentication includes smart cards?
a. Something you know
b. Something you have
c. Something you are
d. Something you do
e. Somewhere you are
Answer: B
Something you have includes smart cards, tokens, and keys. Something you know includes account logons, passwords, and PINs, making answer A incorrect. Answers C and D are incorrect because both something you are and something you do involve measures of personal biological qualities and do not require an external device such as a smart card or key. Answer E is incorrect because somewhere you are is generally associated with either being in a trusted or less trusted location which could be based on GPS coordinates or IP address.
