Despite the names (Konstantin Gavrilenko, Andrei Mikhailovsky, Andrew Vladimirov), the three people who wrote this book are based in the UK and are the founders of an IT security company there by the name of Arhout. They have decided to impart gems of knowledge to us about wireless networks and how to kept hackers out. Or alternatively if you possess a degree of moral flexibility, you could use this book to learn about hacking into said networks.
