Final Answer:
The security manager implemented A physical control. The correct option is A) A physical control because a mantrap, which detects an employee's heartbeat, weight, and badge, is a physical control. Physical controls involve tangible measures to secure access to physical locations, and in this case, the mantrap serves as a direct physical barrier to protect the high-security data center.
Step-by-step explanation:
The installation of a mantrap that assesses an employee's heartbeat, weight, and badge constitutes a physical control. Physical controls are measures taken to secure physical access to facilities, systems, or data. In this scenario, the mantrap serves as a tangible barrier that monitors and controls entry to the high-security data center based on specific physiological and credential parameters.
By employing a physical control, the security manager enhances the overall security posture by adding a layer of protection to the physical infrastructure of the data center.
The use of biometric and badge verification in the mantrap aligns with the characteristics of physical controls, which aim to safeguard the physical environment from unauthorized access. The integration of multiple factors, such as heartbeat and weight, enhances the sophistication of the control, making it a robust mechanism for ensuring that only authorized personnel can enter the sensitive area. This approach demonstrates a proactive strategy to mitigate security risks and maintain the integrity of the high-security data center.
In conclusion, the selection of "A. A physical control" accurately categorizes the security manager's implementation of the mantrap. This choice reflects the emphasis on securing the physical aspects of the data center through the use of a technologically advanced access control system, showcasing a strategic and comprehensive approach to protecting valuable assets from unauthorized access.
