Question
Which of the following ensures data is unrecoverable on a lost or stolen mobile device?
A. Device encryption
B. Remote wipe
C. Data backup
D. Fingerprint reader
Answer
B. Remote wipe
Explanation
Remote wipe is the most effective method to ensure data is unrecoverable on a lost or stolen mobile device. This feature allows an authorized user or IT administrator to send a command to the device, instructing it to erase all data stored on it. This process effectively renders the data inaccessible and unrecoverable to anyone who might gain physical access to the device.
Let’s examine why the other options are not the best answers:
A. Device encryption: While encryption is an essential security measure that protects data from unauthorized access, it doesn’t guarantee that the data is unrecoverable if the device is lost or stolen. A determined attacker with enough time and resources might eventually break the encryption.
C. Data backup: Backing up data is crucial for data preservation and recovery, but it doesn’t address the issue of making data unrecoverable on the lost or stolen device itself.
D. Fingerprint reader: This is a method of authentication that can prevent unauthorized access to the device, but it doesn’t ensure that the data becomes unrecoverable if the device falls into the wrong hands.
Remote wipe stands out as the best solution because it actively removes the data from the device, leaving nothing for potential thieves or unauthorized users to recover. This feature is particularly important in corporate environments where mobile devices may contain sensitive company information.
It’s worth noting that for remote wipe to be effective, the device must be connected to a network (cellular or Wi-Fi) to receive the wipe command. Many mobile device management (MDM) solutions include remote wipe capabilities, allowing organizations to protect their data even when devices are lost or stolen.
