Easy to use – I did about half of the recommendations in under an hour. I’m a writer and I run a business from home. I’m not so technically adept. When I travel, I hate packing up all my equipment and putting things in storage to make sure that, in the unlikely event the house is robbed, all my data is safe and I could easily restart my business from a backup in the cloud. This book is a “paint-by-numbers” approach to security for every aspect of a computer system, from backups to email to encrypting the physical drives. There’s really nothing else on the subject, unless you want to read technical blogs for days. This book has it all in one place and makes it easy for even a normal person (like me).
