Explanation
If a smartphone is stolen, remote wipe destroys the data remotely and device encryption ensures data is unreadable without the decryption key, providing the strongest protections against sensitive data loss.
Common mistakes.
- A. Tethering shares the device's internet connection with other devices and provides no protection against data loss on a stolen device.
- B. A screen lock PIN prevents casual access but does not protect data if the device storage is physically extracted or a bypass is used.
- D. An email password only protects the email account and does not secure other sensitive data stored on the device.
- E. GPS tracking helps locate the device but does not prevent an attacker from accessing or copying data once they have physical possession.
Concept tested. Mobile device data protection - remote wipe and encryption
