Question

The it security team at a large company is implementing more robust authentication measures to safeguard sensitive data and systems. the team is exploring multifactor authentication (mfa) options to bolster security. the company deals with highly confidential information and requires a robust solution. the team has narrowed the choices and is evaluating which aligns best with their security needs. which multi-factor authentication method utilizes unique physical characteristics of individuals to verify their identity?

A. Token-based authentication
B. Knowledge-based authentication
C. Biometric authentication
D. Time-based authentication

Answer 1

The method of multi-factor authentication that uses unique physical characteristics to verify identity is biometric authentication. It is secure due to the difficulty in replicating biological traits, and fits well with companies handling confidential data.

Step-by-step explanation:

Multi-Factor Authentication

The multi-factor authentication method that utilizes unique physical characteristics of individuals to verify their identity is C. Biometric authentication. This type of authentication is considered one of the most secure forms of MFA because it relies on the unique biological traits of an individual, which are extremely difficult to replicate or steal. Examples of biometric identifiers include fingerprints, facial recognition, iris scans, and voice recognition.

Biometric authentication is particularly relevant for companies dealing with highly confidential information, where ensuring that only authorized individuals gain access to sensitive data systems is paramount. Compared to other forms of authentication, biometrics can provide a more seamless and user-friendly experience while offering a higher level of security. However, it's also important to consider the privacy implications and the need for proper data protection measures when implementing biometric systems.
