The correct answer identifies physical access controls as tools and devices that help secure a physical space by restricting access to authorized personnel. Locks, swipe cards, and video cameras are examples of mechanisms that help maintain the security of a physical environment.

Locks provide the most fundamental level of security by controlling entry to buildings or areas. Swipe cards enable controlled access; only individuals with valid credentials can enter designated spaces. Video cameras enhance security by monitoring activities, allowing for real-time observation and recording of events, which is crucial for identifying unauthorized access or suspicious behavior.

Other options include components that belong to different security categories. Firewalls, data encryption, and antivirus software pertain to network and information security rather than physical security. Key fobs, security alarms, and intrusion detection systems also relate to physical access controls; however, the first option includes the basic and most commonly recognized devices used in securing physical locations. Password protection and encryption are clearly digital security measures, which do not fall under physical access controls, while surveillance cameras, while useful, are not explicitly focused on physical barrier control compared to locks and swipe cards.
