Explanation:
Cable locks are theft deterrent devices that can be used to tether a device to a fixed point keep smaller devices from being easy to steal.
Incorrect Answers:
A: Screen-lock is a security feature that requires the user to enter 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. However, this does not
deter theft.
B: 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.
D: Disk and 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. However, this does not deter theft.
