When you lose a USB flash Drive, you need to be concerned about more than the cost of replacing that flash drive. More than likely, gigabytes of portable data travel in and out of your offices each day on such devices. Usually, USB flash drives are neither issued nor managed by IT, rarely reported lost or stolen, or may even become permanently "lost" at the bottom of the desk or a bag.
Although these devices typhically cost less than $20.0, the data transported on them is usually every bit as sensitive as the data on laptops. Fortunately, you can protect the data on laptops and flash drives without too much work or effort using encryption.
