Visitors to a secured facility are required to check in with a photo ID and enter the facility through an access control vestibule. Which of the following best describes this form of security control?

The correct answer is Physical. Physical security controls involve tangible measures to protect an organization's assets, including people, property, and data. Requiring a photo ID for check-in and using an access control vestibule (mantrap) are direct examples of physical barriers and procedures designed to restrict unauthorized access to a facility. Managerial controls are policies, procedures, and guidelines (e.g., security awareness training, risk assessments). Technical controls are hardware or software-based solutions (e.g., firewalls, encryption, intrusion detection systems). Operational controls are the day-to-day activities and processes that ensure security (e.g., incident response, backup procedures). While these other control types are crucial for overall security, the scenario specifically describes physical methods of access restriction.
