This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff on-line! See this thread for details.
There is an entire chapter on security which comes an overview of the topic and describes how to set up various different types of login modules. In addition, there is a full chapter on securing web applications. And just about every other chapter covers security for its specific technology. You could say that security was one of the primary foci of the book.
