Feature: Wireless & Mobile Securing Linux laptops By Rick Cook on January 07, 2008 (9:00:00 PM)
Print Comments Laptop and notebooks are being stolen at an ever-increasing rate. In 2004, Safeware Insurance which sells computer insurance, estimated 600,000 laptop and notebooks a year were being stolen. In 2006 an estimated 750,000 were being swiped, according to Absolute Software a company that makes computer tracking products -- and does not support Linux. LoJack For Laptops, another computer tracing company -- which also does not support Linux -- says FBI statistics show 2 million laptop and notebook computers were stolen in the US in a recent year. While the figures may not agree in detail, they all show that laptop and notebook theft is a major problem -- and if you're not careful, your Linux laptop might be next.

Can you encrypt a LVM that has /home on it (or just the ext3 in the LVM)?
What about /boot on a USB dongle. I actually think I know how to do this at install with Disk Druid. But can you unmount /boot after booting up (don't want to walk around with the dongle on the system, wear it around my neck on a lanyard).
