Lost or stolen mobile devices are a growing data security threat, yet there's no need to panic over sensitive data falling into the wrong hands if it's protected. That's where USB Flash Security from Kashu System Design comes in. It's a free USB security utility for mobile devices.

USB Flash Security's compact, tabbed interface displays all installed disk drives on your PC, but the software will only install on those drives with USB access. It's a keep-it-simple layout: there's a display window, file menus for Operations and Help, Exit and Update buttons, and the Install command bar, but that's it. We inserted a USB flash drive, and USB Flash Security immediately identified it. Selecting the drive for installing the software called up a password creation wizard that has an interesting option to set your password hint to display when you hover the cursor. We installed the software, removed the drive, reinserted it, and copied some files to it, calling up the password entry dialog. We entered the password and gained access to the USB drive's volume, transferred the files, ejected the drive, and reinserted it again. Clicking the drive displayed the USB Flash Security executable, which we then clicked to recall the password entry dialog. We entered the password and gained access to the data. We like the fact that the password entry field doesn't automatically appear when you try to access the drive since there's no reason to help thieves figure things out.

Kashu is a Japanese developer that is entering the global software market, and its documentation is written in somewhat fractured English that occasionally takes some figuring out. However, the Help file is not only clear and concise but helpful as well. All told, USB Flash Security is an easy-to-use tool that offers effective password protection for mobile data devices.
