Types of Hardware Devices for Two-Factor Authentication
Question
Adam works as a Security Analyst for Umbrella Inc.
CEO of the company ordered him to implement two-factor authentication for the employees to access their networks.
He has told him that he would like to use some type of hardware device in tandem with a security or identifying pin number.
Adam decides to implement smart cards but they are not cost effective.
Which of the following types of hardware devices will Adam use to implement two-factor authentication?

A. B. C. D.D.
Adam has been tasked with implementing two-factor authentication for the employees of Umbrella Inc. Two-factor authentication is a security measure that requires users to provide two forms of identification before being granted access to a system. This is typically achieved through the use of something the user knows (such as a password) and something the user has (such as a physical token).
In this case, the CEO of Umbrella Inc. has requested that a hardware device be used in combination with a security or identifying pin number. Adam has decided that smart cards would be an effective way to implement this security measure, but they are not cost-effective.
Therefore, Adam must consider alternative hardware devices that can be used for two-factor authentication. The options are:
A. Biometric device: A biometric device uses unique physical characteristics, such as fingerprints or facial recognition, to identify a user. While biometric devices are highly secure and difficult to spoof, they can be expensive and require specialized hardware.
B. One Time Password: A one-time password (OTP) is a password that is only valid for a single use or a short period of time. OTPs can be generated using a variety of methods, such as a mobile app or a hardware token. While OTPs are relatively easy to implement and cost-effective, they can be vulnerable to phishing attacks.
C. Proximity cards: Proximity cards are physical cards that use radio frequency identification (RFID) technology to identify a user. They can be used to grant access to physical spaces or to log in to computer systems. While proximity cards are relatively easy to use and cost-effective, they can be vulnerable to cloning or theft.
D. Security token: A security token is a physical device that generates a unique code or password that is used for authentication. Tokens can be hardware-based (such as a USB key) or software-based (such as a mobile app). While security tokens are highly secure and difficult to spoof, they can be expensive and require specialized hardware.
Of these options, the most likely choice for Adam would be a security token. While biometric devices are highly secure, they can be expensive and require specialized hardware. One-time passwords are cost-effective, but they can be vulnerable to phishing attacks. Proximity cards are relatively easy to use and cost-effective, but they can be vulnerable to cloning or theft. Security tokens are highly secure and difficult to spoof, making them an effective choice for two-factor authentication.
