Joseph has just been hired on to a contractor company of the Department of Defense as their Senior Security Analyst. Joseph has been instructed on the company’s strict security policies that have been implemented, and the policies that have yet to be put in place. Per the Department of Defense, all DoD users and the users of their contractors must use two-factor authentication to access their networks. Joseph has been delegated the task of researching and implementing the best two-factor authentication method for his company. Joseph’s supervisor has told him that they would like to use some type of hardware device in tandem with a security or identifying pin number.
Joseph’s company has already researched using smart cards and all the resources needed to implement them, but found the smart cards to not be cost effective. What type of device should Joseph use for two-factor authentication?

A.
Proximity cards

B.
Security token

C.
Biometric device

D.
OTP

Explanation:
A security token (sometimes called an authentication token) is a small hardware device that the owner carries to authorize access to a network service. The device may be in the form of a smartcard or may be embedded in a commonly used object such as a key fob. Security tokens provide an extra level of assurance through a method known as two-factor authentication : the user has a personal identification number (PIN), which authorizes them as the owner of that particular device; the device then displays a number which uniquely identifies the user to the service, allowing them to log in.
