ある企業は、内部者による盗難により、毎年数百台のモバイルデバイスを紛失しています。盗難抑止のため、これらのデバイスが社外で使用できないようにしたいと考えていますが、デバイスが誤って社外に持ち出された場合でも、翌日に再利用されることを阻止したくありません。この問題の解決策として最適なものはどれでしょうか?
正解:C
"Geofencing capabilities in a mobile device management (MDM) solution allow administrators to define a virtual perimeter-based on GPS or network identifiers-around a physical location. Devices that exit the geofence can be automatically restricted or disabled, preventing them from functioning outside the approved area, and will automatically resume normal operation once they re-enter the perimeter. This approach deters unauthorized removal while allowing legitimate, temporary off-site use (for example, if a device is accidentally taken home and returned)."

"Implement geofencing as part of an enterprise MDM strategy to enforce location-based access controls.
Unlike remote wipe- which is irreversible-geofencing ensures devices remain usable when returned, and unlike encryption or simple location monitoring, it enforces a policy that directly blocks functionality outside authorized zones."
- CompTIA CASP+ CAS-004 Exam Objectives (v7.1), Section 4.3: Mobile Device Management, p. 26 By configuring a geofence around the warehouse, the company ensures that mobile devices become non- functional if removed beyond the defined boundary, yet automatically restore full functionality when brought back, effectively deterring theft without risking permanent data loss or requiring user intervention.
