Which of the following will BEST prevent an employee from using a USB drive to copy files from
desktop computers?

A.
Restrict the available drive allocation on all PCs

B.
Disable universal serial bus (USB) ports on all desktop devices

C.
Conduct frequent awareness training with noncompliance penalties

D.
Establish strict access controls to sensitive information

Explanation:

Restricting the ability of a PC to allocate new drive letters ensures that universal serial bus (USB)
drives or even CD-writers cannot be attached as they would not be recognized by the operating
system. Disabling USB ports on all machines is not practical since mice and other peripherals
depend on these connections. Awareness training and sanctions do not prevent copying of
information nor do access controls.
