"Hacking Linux Exposed is a very good read. It does a great job of staying focused and interesting, without skimping on the actual details you need to secure your systems and understand the threats. The countermeasures are real and specific, allowing administrators to use this book as a tool to secure their own systems.

At many times I wished that the book were more Unix-centric than simply Linux centric. Many of the issues are similar, and the countermeasures would simply be broken down into *BSD vs Linux vs Solaris, etc. However that would have made reading the countermeasures a bit more difficult. As it is, many of the issues have similar or identical countermeasures, regardless of OS, so administrators should be able to extend what is said to their Unix OS of choice without too much trouble.

The Linux focus allows the authors to get much more in depth than they were able to in Hacking Exposed , which was disjointed at times, unable to really probe each issue. However the opposite is also true --- since they wanted to focus on Linux-specific attacks, they do not go into general attacks, such as JavaScript, cross site scripting, and other browser-related problems, for example. For these types of attacks you should look elsewhere. I think keeping the focus clean is very much worth it."
