Perish the thought, but if your Mac were stolen, would you worry about the thief — or whoever the Mac was fenced to — seeing your email, photos, financial data, and other sensitive information? OS X’s built-in FileVault encryption technology can ensure that your Mac’s contents are safe from prying eyes, but if you’re hesitant to entrust your data to FileVault before you understand how it works, “Take Control of FileVault” will dispel any misconceptions, answer your questions, and get you running FileVault with confidence. The book normally costs $10, but the 30% MUG discount drops that to $7. Learn more about the book and buy it via the coupon-loaded link below.
Security expert Joe Kissell begins by demystifying FileVault in a quick FAQ that explains, among other things, how it is that you can work with your startup drive normally even though all the data on it is encrypted. It also explains the distinction between today’s FileVault 2 and Legacy FileVault, which was completely different. After the FAQ, Joe provides detailed steps for activating and using FileVault on both your startup volume and external drives. He also explains how FileVault interacts with your backups and how to use Find My Mac to lock or wipe a stolen Mac’s drive once you’ve turned on FileVault.
Put bluntly, even ignoring personal data, if you have a MacBook that contains business data, such as customer names and addresses, credit card numbers, or the like, you should be enabling FileVault. Too many laptops are nicked from coffeeshops or left in cabs to risk leaving the drive unencrypted.
Additional topics include making and using encrypted disk images, third-party software that can encrypt just a single file or folder, and accessing special FileVault features from the command line.
