* The question asks about the most effective security mechanism against physical intrusions due to stolen credentials for data center access. The company is utilizing multifactor authentication, which is a layered approach to securing data and applications where a system requires a user to present a combination of two or more credentials to verify a user's identity for login1.
* The answer is biometrics security hardware, which is a type of credential that uses the physical characteristics of a user, such as fingerprint, iris, or face, to authenticate the user2. Biometrics security hardware is the most effective security mechanism against physical intrusions due to stolen credentials, because it is difficult to forge, copy, or share biometric data, and it provides a strong link between the user and the identity3.
* Access card readers, access control vestibule, and motion detection cameras are not the correct answers, because they are not the most effective security mechanisms against physical intrusions due to stolen credentials. Access card readers are a type of credential that use a physical token, such as a card or a key, to authenticate the user4. Access card readers are vulnerable to physical intrusions due to stolen credentials, because the cards or keys can be lost, stolen, or duplicated. Access control vestibule is a physical security feature that creates a buffer zone between the outside and the inside of a facility, where users have to pass through two sets of doors and be verified before entering5. Access control vestibule can deter unauthorized access, but it does not prevent physical intrusions due to stolen credentials, because the intruders can still use the stolen credentials to pass through the vestibule. Motion detection cameras are a type of surveillance device that capture images or videos of any movement in a specific area. Motion detection cameras can monitor and record physical intrusions, but they do not prevent them, and they may not be able to identify the intruders if they use disguises or masks. References:
