Zen and the Art of Information Security
While security is generally perceived to be a complicated and expensive process, Zen and the Art of Information Security makes security understandable to the average person in a completely non-technical, concise, and entertaining format. Through the use of analogies and just plain common sense, readers see through the hype and become comfortable taking very simple actions to secure themselves. Even highly technical people have misperceptions about security concerns and will also benefit from Ira Winklers experiences making security understandable to the business world. Mr. Winkler is one of the most popular and highly rated speakers in the field of security, and lectures to tens of thousands of people a year. Zen and the Art of Information Security is based on one of his most well received international presentations.
*Written by an internationally renowned author of "Spies Among Us" who travels the world making security presentations to tens of thousands of people a year
* This short and concise book is specifically for the business, consumer, and technical user short on time but looking for the latest information along with reader friendly analogies

Zero-Day Exploit
Countdown to Darkness
There exists a 0-day vulnerability in a particular line of SCADA Master products that are widely used in petrochemical facilities. Furthermore, since the telemetry between the Master and the RTUs (the units located at valves, gauges, etc.) is particularly fragile under attack, the attackers are able to take a two-tiered approach to the damage they cause. The vulnerability is designed to simply replace a small bit of code in the SCADA Master so that upon communication with the RTUs, it will unpredictably send invalid data; the way in which the communications are invalid also varies somewhat. The symptoms of this appear not at the Master level, but in the RTUs themselves, which have unpredictable results. The first set of disasters occur as valves fail to close or open, or particular RTUs cease providing data. It takes a bit of time for law enforcement to have a solid handle on things, as they are currently battling their own issues, but they notice the pattern. The SCADA systems are immediately segmented from other networks, and work begins on replacing RTUs. This, however, has no effect, and as time passes the ripples of the attack spread. Gas stations run out of gas, followed shortly by freight carriers. Private individuals and local police and fire departments are not far behind. Disaster can only be prevented by Reuben, an elite cyber-security researcher who stumbles across the plot while contracting for the federal government.

How to Be Invisible
The Essential Guide to Protecting Your Personal Privacy, Your Assets, and Your Life Revised Edition
It's hard to say how private investigators would react to books like J. J. Luna's How to Be Invisible--while it makes their jobs a lot harder, most of them are paid by the hour. If you want to withdraw from the snooping eyes of the government, corporations, stalking ex-boyfriends, or practically anyone else, this practical, down-to-earth guide will help you and your family vanish. It's not a glamorous James Bond life Mr. Luna is inviting you to take part in; it's probably much like the life you're living right now. Spending much of the early part of the book frightening the reader with tales of stalkers and mistaken identities, the author successfully makes his case that a few adjustments to an individual's personal information flow can make a life-or-death difference. While getting his plan off the ground will take a bit of planning and effort (you have to move at least once to clear your trail), it is sustainable and worthwhile even for those who think they have nothing to hide. Learn about anonymous travel and purchase, using trusts and corporations to keep your assets private, and how recent laws (the book's date of publication is 2000) significantly affect older methods of guaranteeing privacy. Luna makes no claim to know the law where you live and suggests that you consult a trusted local attorney before implementing most of his advice. Just knowing how easily a criminal can learn about and exploit your personal information will make you want to do just that. --Rob Lightner
