This book is dedicated to the army of skilled people who have a vision for a world in which ideas may be freely communicated and where the application of those ideas can benefit all of society. The Linux operating system platform is one of the fruits of the exchange of such ideas, their implementation and ultimately their use the world over.This book can not cover everything that is to be known about securing Linux, but without input from many generous folks who gave their time and who continue to take great care and have pride in their efforts this book could not be a powerful tool in helping you to secure your Linux servers.

Ronald P. Reck was raised and educated in the Detroit Metropolitan area and on occasion has enough time to miss the friends and culture of the place he still calls home. He is formally trained in theoretical syntax and remains fascinated by language and what it reveals about being human. A passion for linguistics and intensity with computers afford him gainful employment using Perl, XML, and Semantic Web technologies running, of course, under *nix. He prides himself on developing scalable, open source architectural strategies for difficult problems. He resides near our nation's capital with his lovely wife Olga and two cats.

Timothy Scanlon is an IT industry veteran who has worked in the US and internationally on a variety of IT and security projects. He has done work in the public and private sectors for a number of Fortune 500 firms, as well as startups like UUNet. In the public sector he has worked as a civilian contractor at various R&D facilities, departments, and branches. His professional interests include cryptography, application & infrastructure design, security, games theory, and simulation and modeling. He thinks that Linux has come a long way from the days when it would all fit on a few floppies.
