A Great Step-By-Step Guide You'd be Foolish Not to Follow

This reviewer is a 60+, female, self-trained MAC user currently in OS10.8.1 and getting ready to buy a new MAC with Mavericks OS. I purchased and read Marc’s book cover to cover in preparation for understanding the scope of my commitment to get my new Maverick OS computer set-up in the most optimal way, for my home-use network. I want to get it hardened from the get-go. This was the best forty odd-dollar investment I could have made.

Practical Paranoia for the non-paranoid...

I became a client of Marc’s five or six years ago when I said goodbye to Windows, became a Mac shop and put in an OS X server. So when Marc announced his new book, Practical Paranoia, I didn’t waste any time buying a copy.

The reason is simple, when Marc tells you something, you can take it to the bank.

The book is clean, well organized, designed to be completely accessible for the non-geek, and provides step-by-step screen shots and instructions on how to save yourself from the nightmare of data loss or breach.

Best Book on the Subject

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).
