A technician is creating an MDM policy using hardening techniques that are unique to each user. Which of the following techniques is the technician using?
MDM hardening often includes enforcing stronger authentication on mobile devices. The phrase “unique to each user” points to something inherent to the individual—biometrics—rather than something the user knows (password/pattern) or something they have (PIV/smart card). Quentin Docter explains: “Biometric devices use physical characteristics to identify the user. This type of authentication is considered something that you are,” and lists common implementations including “fingerprint… scanners.” This exactly matches a fingerprint, which is unique per person and commonly enforced via device policies in MDM environments.
Docter also notes mobile devices increasingly implement biometrics for access control, specifically citing “fingerprint access control” adopted by manufacturers. A drawn pattern and a password are knowledge factors and can be shared/observed, while a PIV card is a possession factor (something you have) and can be lost or loaned. Because the question specifies a hardening technique “unique to each user,” the best match is the biometric factor: fingerprint (B).
