Computers are wonderful. The internet is fantastic. You are not safe online ... unless you work at it.

Every week there are several new revelations about security weaknesses in our hardware and software, theft of millions of pieces of personal information, and new software and techniques to combat cybercriminals.

The goals of this book are to help motivate you to take some action and to teach you how to think about the privacy and security of your information and devices. But tt's not so much a "how to" book (i.e., what buttons to press) as a "why to" book because "how to" is limited to the next hardware or software update or data breach that exposes yet another problem. "Why to" teaches how to think about this problem so you can better understand the changes coming and when to take action..

This book discusses five levels of security: Physical, Access, System, Application and Behavioral for the general user in easy to understand, practical terms.

The author has nearly 50 years experience with all types and aspects of computers, software, and policy from many different perspectives.
