Pete, an IT Administrator, needs to secure his server room. Which of the following mitigation methods would provide the MOST physical protection?

Sign-in and sign-out logs are administrative controls that record access but do not physically prevent unauthorized entry.

A mantrap creates a physical airlock between two areas, requiring successful authentication before the second door opens and preventing tailgating or unauthorized entry. Unlike passive controls such as logs or cameras, it actively stops unauthorized individuals from entering. It is the most direct physical barrier that can deny access in real time.

Video surveillance is a detective control that records events after they occur but does not physically stop an intruder.

HVAC is an environmental control that manages temperature and airflow and provides no access restriction or physical barrier.
