This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
This is the first book to focus on design patterns for implementing application security in J2EE and Web Services. It attempts to cover the broad spectrum of securing enterprise apps with a focus on developers. Unlike many other books that include chapters on security, this book focuses on it and takes you through the basics all the way to baking security into an application from the ground up with best practices, pitfalls, and reality checks. It is not a theoretical book, it goes into the real world challenges associated with building secure applications.
