We therefore hope that you enjoy this book, which has been carefully crafted to meet our standards of quality and unbiased coverage. coverage. We are always interested in your feedback or ideas for new titles. Perhaps you’d even like to write a book yourself. Whatever the case, reach out to us at Introduction I wrote this book to solve two very specific problems for my fellow IT professionals. We all get too many questions from individual computer users who are worried about the security of their personal computers, tablets, and phones. In the industry, the acronym RTFM is hurled at beginners for asking naïve questions. But that is not an appropriate answer to a user concerned about computer security. These folks ask good and important questions that deserve serious answers. A few years ago, after repeating the same answers many times, I started to look for the right book to recommend. There are many good books on computer security but most of them drift into security for system administrators; this confuses ordinary users and leaves them uncertain. And no one needs to be reminded that the details of computing change rapidly, but the basic principles stay the same. Users need knowledge that will give them a foundation to build on as the details of security issues change. Many books on personal computer security tend to be highly prescriptive with lots of screenshots and values to fill into specific fields. This is nice, but this aspect of computing changes rapidly and many of these books become confusing within months of publication because interfaces change. Users need simple explanations of what they are doing and why they are doing it, not outdated, detailed instructions. The rate of change has escalated as products adopt automated update practices. Products evolve much more rapidly than a few years past. To stay safe during rapid change, computer users must have a firm grasp of what they are protecting themselves against, how the protections work, and why they need to protect themselves. The book is divided into three sections. The first section explains how computing has developed, how cybercrime has become a serious problem, and the extent of its severity. The second section examines what government and industry have done to respond. The third section relies heavily on the previous two sections and focuses on what you can do to protect yourself and what to do when you become a victim. Throughout, I have tried to maintain focus on what is wrong, why it is wrong, and how the response works so that a user can apply the advice to any computer they work with. If I have succeeded in my goal, the users who read this book will be informed, not quite so nervous, and prepared to avoid or actively resist the security issues that plague them. This book will not eliminate user questions to security issues that plague them. This book will not eliminate user questions to IT professionals, nor will it eliminate the need for operating system and product security documentation. In a world where substantial updates are automatically applied every month, a book like this would not be useful for long if it was only a snapshot of cybersecurity at one moment in time. Readers may be tempted to skip to the last two chapters. If you are under attack and feel the need to take immediate action, do skip ahead. But then go back and read the preceding chapters. You will find that the recommendations in the final chapters will make more sense, are easier to accept, and can be applied more effectively after you have the background the earlier chapters provide. Acknowledgments I owe a tremendous debt to all my former colleagues at CA Technologies, Inc. I learned from my colleagues and customers every day I worked at CA. I had daily opportunities to confer with security specialists, antimalware builders, and encryption experts. I talked with customers who had been hacked, asking how it happened and how it affected their business and them personally, how they could have avoided it, and what they would do to prevent it in the future. Since I retired from CA and began to concentrate on writing about computing, I have pursued another passion: public libraries. I serve on the board of the Whatcom County Library System in Washington State. The library and its patrons inspired me to focus on personal cybersecurity. Special recognition goes to the Executive Director, Christine Perkins, and IT Services Manager, Geoff Fitzpatrick. My good friend Efraim Moskovitz was my constant sounding board while writing this book. He pushed me on and reined me in as needed. Efraim and I worked together on the CA Council for Technical Excellence for several years and Efraim contributed several articles to the CA Technology Exchange , which I edited. Efraim was technical reviewer for both of my previous books with Apress. My online acquaintance Shawn Coyne made some
