BitLocker on their customers' Windows Vista system, from the basics to common misconceptions to configuration and encryption techniques.
Rarely does a month go by without a news report about a company or government agency that suffers some kind of loss in the form of a stolen laptop or PC. Often the theft is nothing more than an attempt to resell the hardware for fast cash, but sometimes it's a specific attempt to steal highly sensitive data.
Computers with hardware-level encryption built in can make such data theft prohibitively difficult. But such machines are expensive, and they are not always a practical solution.
Make sure you understand the basics of BitLocker.
