OK, the review of the 7 Full Disk Encryption is now complete. The results are at: http://www.xml-dev.com/blog/index.php?action=viewtopic&id=250 I did an analysis of various FDE solutions to find the best one for my needs. The key thing I was interested was that it must be AES 256, reasonably fast, inexpensive, and offer key recovery in case of password loss. Compusec is great for home / personal use. It is cheap i.e. $0.00 (Free), and does not slow down the computer as much as the other products. But that is because it only support 128 bit AES, which is a major drawback as most enterprise settings require at least 256 bit AES. Compusec also has a great online support forum where you can get your questions answered by Compusec employees and other experienced users. I ended up purchasing both Utimaco and Pointsec. They are excellent products. They both support AES 256. The downside is that they are little bit expensive (Pointsec:$170 ; Utimaco:$200) and slow. The best thing is they both offer great password / encryption key recovery capabilities. You can create a recovery disk with both products. They also offer password recovery using Challenge / Response sequence, where the IT Helpdesk can perform a Challenge/Response sequence with the user to help them recover the password or reset it to a new one. Off course Challenge/Response password recovery is the NOT most secure, especially if the user is remote, but you have the option to disable it on the laptop if you want. . saqib http://www.full-disk-encryption.net On 11/1/06, Jason Muskat, GCFA, GCUX, de VE3TSJ <Jason () techdude ca> wrote:
Hello, We deployed FDE on every laptop (about 150) in the organization I work for including my own. The FDE software installs itself on every drive wished including the boot drive "c:" and requires the use of a pre-boot-loader before Windows is loaded. I found no discernible speed difference. The pre-boot-loader is very transparent to Windows. The only issues I have come across is one HDD became corrupted. Windows Automated Recovery would have easily fixed this issue. Due to an Admin oversight an Admin Key, which allows one to boot a CD from the FDE boot-loader, was missing. At that point the drive became very difficult to recover. So much, it was low-level formatted and backups were restored to a new drive. Key Management is easy but very procedure driven. If parts of the procedure are skipped issues such as a simple disk recovery become very difficult. Regards, -- Jason Muskat | GCFA, GCUX - de VE3TSJ ____________________________ TechDude e.
