A security administrator has concerns regarding employees saving data on company provided mobile
devices. Which of the following would BEST address the administrator’s concerns?

A.
Install a mobile application that tracks read and write functions on the device.

B.
Create a company policy prohibiting the use of mobile devices for personal use.

C.
Enable GPS functionality to track the location of the mobile devices.

D.
Configure the devices so that removable media use is disabled.

Explanation:
Mobile devices can be plugged into computers where they appear as an additional disk in the same way
as a USB drive. This is known as removable media. This would enable users to copy company data onto
the mobile devices. By disabling removable media use, the users will not be able to copy data onto the
mobile devices.
Incorrect Answers:
A: A mobile application that tracks read and write functions on the device (if such an application exists)
would only monitor the activity. It wouldn’t stop data being written to the device.
B: Policies provide guidelines. A policy prohibiting the use of mobile devices for personal use would not
stop data being written to the device as the policy would still need to be enforced.
C: Global Positioning System (GPS) tracking can be used to identify its location of a stolen device and can
allow authorities to recover 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. This would
not prevent data being written to the device.
