What is meant by physical access control?

• A. Restrictions on who can access digital files
• B. Protocols to secure online transactions
• C. Mechanisms used to restrict access to physical locations to authorized personnel only
• D. Monitoring of network traffic for unauthorized access

Answer: (C)

Physical access control refers to the mechanisms and strategies employed to restrict access to physical locations, ensuring that only authorized individuals can enter or utilize those spaces. This encompasses a variety of methods and technologies designed to protect physical assets, such as buildings, facilities, and equipment.

For example, physical access control can involve the use of locks, security personnel, key card entry systems, biometric scanners, and surveillance cameras. Such measures are crucial in preventing unauthorized individuals from gaining access to sensitive areas, protecting both the personnel within those areas and the assets housed there.

In contrast, the other choices focus on different aspects of security. Restrictions on access to digital files are related to information security, dealing with data stored electronically rather than physical locations. Protocols to secure online transactions pertain to cybersecurity measures that protect data during digital exchanges, while monitoring network traffic for unauthorized access involves safeguarding network infrastructure and data instead of physical premises. Each of these aspects plays an important role in security but addresses different areas of concern.
