Information stored on the hard drives at Redstone Arsenal is about to get a little more secure. Starting May 3, the Redstone Network Enterprise Center System Configuration Team will begin the process of enabling a feature of Microsoftâs BitLocker on everyoneâs computer that will require them to enter a PIN each time they turn their computer on, according to Douglas Dub, branch chief at the system support branch of the Network Enterprise Center. âYour hard drive is already encrypted, but what we are doing now is requiring a PIN before you log in,â Dub said. The new login process will go something like this: turn on your computer, enter your BitLocker PIN, insert your Common Access Card, hit control, alt, delete and then proceed to login like normal.
