Implementing Two-Factor Authentication for Secure Server Room

D.

The BEST solution for securing a server room using two-factor authentication would be D. Biometric lock and hardware token.

Two-factor authentication requires two methods of identification to grant access to a secure location, system or account. Biometric locks can use unique physiological characteristics such as fingerprints, iris scans or facial recognition to grant access. These methods are difficult to forge or replicate and provide a high level of security.

A hardware token can be a small device that generates a unique code for each user, which is required for access to the server room. This provides a second layer of authentication beyond just the biometric data.

Option A, door lock and mantrap, provides physical security but does not offer two-factor authentication, which is essential for ensuring a high level of security.

Option B, server lock and badge reader, provides some level of security, but it is not as secure as biometric locks and hardware tokens. Badge readers can be lost or stolen, and server locks can be easily bypassed.

Option C, security guard and entry control roster, provides physical security and control of access, but it does not meet the requirements for two-factor authentication.

In conclusion, implementing a biometric lock and hardware token would provide the BEST security for the server room, ensuring that only authorized individuals with valid identification and a unique access code would be granted entry.
