Which of the following controls can be implemented together to prevent data loss in the event of theft of
a mobile device storing sensitive information? (Select TWO).

A.
Full device encryption

B.
Screen locks

C.
GPS

D.
Asset tracking

E.
Inventory control

Explanation:
A: Device encryption encrypts the data on the device. This feature ensures that the data on the device
cannot be accessed in a useable form should the device be stolen.
B: Screen locks are a security feature that requires the user to enter a PIN or a password after a short
period of inactivity before they can access the system again. This feature ensures that if your device is left
unattended or is lost or stolen, it will be difficult for anyone else to access your data or applications.
Incorrect Answers:
C: Global Positioning System (GPS) tracking can be used to identify its location of a stolen device and can
allow authorities to locate the device. However, for GPS tracking to work, the device must have an
Internet connection or a wireless phone service over which to send its location information.
D: Asset tracking is the process of maintaining oversight over inventory, and ensuring that a device is still
in the possession of the assigned authorized user.
E: Inventory control is an aspect of asset tracking and the overseeing of inventory. It does not prevent
data loss.
