What security control enforces a virtual boundary based on real-world geography?

• A. Geofencing
• B. Geolocation-based access control
• C. Geo-blocking
• D. Geographic boundary enforcement

Answer: (A)

Geofencing creates a virtual boundary around real-world geography and enforces security policies based on whether a device or user is inside or outside that boundary. It uses location data from GPS, Wi‑Fi, or cellular signals to detect entry or exit and can trigger actions like granting or denying access, sending alerts, or altering app behavior. This direct mechanism—defining a geographic perimeter and enforcing rules as boundaries are crossed—is why it’s the best fit for the question. Related ideas exist (for example, using location as a condition in access decisions or restricting content by region), but they do not describe the specific boundary-enforcement control that geofencing provides.
