The practice of restricting entrance to a property is called?

• A. Access control
• B. Patrol management
• C. Security screening
• D. Gatekeeping

Answer: (A)

Access control is the system of procedures and physical measures that limit who can enter a property and under what conditions. It combines barriers (doors, gates, locks), credentials (badges, keys, codes), verification processes, and monitoring to ensure only authorized individuals gain access. For example, a building might require badge readers and visitor escort policies to restrict entry. The other terms describe related security activities but not the overall mechanism for controlling entry: patrol management is about ongoing monitoring and response, security screening focuses on checking people or items at entry, and gatekeeping refers to broader or more informal control of who is allowed in.
