Following a recent survey of available USB flash-memory storage devices (colloquially known as ‘USB sticks’ or ‘USB memory sticks’) we’ve decided to adopt the SafeStick device from BlockMaster AB as our preferred portable backup device. This is issued to laptop users who may be out of the office for extended periods in remote locations where it may not be possible, or may be highly impractical, to make a VPN connection to the company’s network to backup files. The main features of the SafeStick that make it attractive are:
- All information on the device is forced to be encrypted and protected by a passphrase. It is not possible for the user to establish an unprotected or unencrypted partition.
- Encryption is managed by an AES-256 hardware ‘module’ embedded within the device itself and this ‘module’ has been independently tested.
- The passphrase for accessing the device is forced to be ’strong’.
- The device can effectively cause its contents to ’self-destruct’ if it is subjected to a ‘brute force’ attack.
- No software needs to be pre-loaded or installed onto the host computer.
The use of SafeStick, together with deploying the PGP Whole Disk Encryption product to our laptop hard drives, means that we can be confident that data on our portable media will remain confidential if the devices are lost or stolen.
Currently the SafeStick is significantly more expensive than traditional USB ‘memory sticks’. However, we feel that the peace of mind that it brings to corporate users is worth it.
Within the UK, the main distributor is Softek, and the device is also available from retailers including eXpansys.
