[Part 7 of an occasional series, updating a blog series I ran in early 2009 to reflect changes in the threat landscape. This series will also be available shortly as a white paper.]
Call For Backup
If sensitive information is stored on your hard drive (and if you don’t have something worth protecting on your system, you’re probably not reading this blog), protect it with encryption.
Furthermore, when you copy or move data elsewhere, it’s usually at least as important to protect/encrypt it when it’s on removable media, or transferred electronically. Even if the target storage device is secure from malware or hacking, you also need to be aware of other dangers such as physical risks, transit risks, business-related risks such as an escrow site going out of business and so on.
Consider (seriously!) regularly backing up your data to a separate disk (as a bare minimum) and, where possible, a remote site or facility. Sounds extreme? Think about it.
I’m sure I don’t need to remind you to take care of your passwords as well, do I?
