Which term describes enforcing access policies based on the device's location within defined geographic boundaries?

• A. Geofencing
• B. Geolocation
• C. Geotagging
• D. Wearable Technology

Answer: (A)

Geofencing is the practice of enforcing access policies based on a device's location within defined geographic boundaries. It creates a virtual perimeter around a real area, and security systems can grant, restrict, or adapt access depending on whether the device is inside that boundary. Location data from GPS, Wi‑Fi, or cellular signals determines if the device has entered or left the geofence, triggering conditional access rules such as requiring additional authentication or blocking sensitive resources when outside the allowed area. This differs from geolocation, which is simply identifying where a device is without automatically applying policies. Geotagging adds location metadata to content, not access control. Wearable technology refers to devices themselves and is not the method for enforcing geographic‑based access.
