In this piece Tony Bradley provides some great insight into how Windows BitLocker “drive” encryption works in Vista and Windows 7. Actually BitLocker is not drive – or whole-disk – encryption after all…As Tony states it’s more like whole-volume encryption.
Keep this in mind when securing your laptop and mobile drives. This could create a pretty serious false-sense of security that everything’s locked down when indeed it’s not. Same as the false-sense of security Windows EFS has created over the years.
Anyway, the piece is a good read providing a nice overview of how BitLocker works and is worth checking out.
“A business associate referred our company to Principle Logic when we were seeking a resource to perform vulnerability /penetration testing for our external and internal networks. We found Kevin Beaver to be professional, well informed, and easy to work with. His testing did not disrupt our networks, and his progress updates were timely.
His final report was very thorough and included security recommendations for our network environment. The executive leadership was so impressed with Kevin’s security expertise, they have extended their agreement to continue to perform periodic testing. We highly recommend Kevin Beaver and Principle Logic as a resource for network security testing.”
