The MOST significant security concern when using flash memory (e.g., USB removable disk) is
that the:

A.
contents are highly volatile.

B.
data cannot be backed up.

C.
data can be copied.

D.
device may not be compatible with other peripherals.

Explanation:
Unless properly controlled, flash memory provides an avenue for anyone to copy any content with
ease. The contents stored in flash memory are not volatile. Backing up flash memory data is not a
control concern, as the data are sometimes stored as a backup. Flash memory will be accessed

through a PC rather than any other peripheral; therefore, compatibility is not an issue.
