I would like to thank Jones & Bartlett Learning for this opportunity to write a detailed and practical information security textbook. I would also like to thank Jeff T. Parker, the technical reviewer, for his outstanding feedback and recommendations, and Kim Lindros the project editor. Kim managed the project from beginning to end, reviewing and ferrying all of the pieces that flowed between me and Jones & Bartlett Learning. Kim was a pleasure to work with and made even the most challenging elements of this project simpler. Thanks again, Kim!
