Lock, encrypt, password protect USB flash drive, thumb drive, pen protect usb drive, memory stick and all other portable storage devices.
Now Nohl’s research team has tested that reprogrammability problem in USB controller chips sold by the industry’s biggest vendors: Phison, Alcor, Renesas, ASmedia, Genesys Logic, FTDI, Cypress usb access control and Microchip. They checked versions of each chip both by looking up its published specs and by plugging a device using it into a computer and attempting to rewrite the chip’s firmware.
Banning the use of USB devices or disabling computers’ USB ports isn’t a practical security measure, as so many peripherals now connect via these ports. Therefore, enforcement of USB best practices – particularly encryption – has become the preferred option for ensuring data is secure if a drive is lost or stolen. Enforcing usb secure encryption of data stored on USB drives is now a lot easier than it used to be, particularly since Microsoft introduced BitLocker To Go with Windows 7 But, unless all your PCs run Windows 7, you’ll need an alternative encryption method, as the encrypted data is read-only when accessed on earlier versions of Windows.
