"Throw up a Linux box," comes the chorus whenever there's a need to provide some network service or other without impinging upon the boss's martini budget. Fair enough, but by doing so are you opening security holes you don't know how to find or fix? The newest edition of
Hacking Linux Exposed helps you answer that question and solve many of the security problems you find. To a certain extent this book is a recipe collection in that it describes weaknesses in Linux (calling attention to specific distributions where appropriate). The authors stop short of explicitly showing you how to wage most kinds of attacks, a reasonable thing to do from an ethical point of view even though the instructions can be found easily on the Internet. Rather than do that, they give step-by-step instructions on how to defend against the attacks they catalog. The point is not, "Here's precisely how to bring down a server by means of an ACK storm," but rather, "Here's how to defend against such problems." They do demonstrate plenty of weaknesses, though, as in their coverage of the conversation that goes back and forth between an FTP server and its client.
This book covers pretty much everything you'd want to do with a Linux machine as a network server. Read it and see some of the weaknesses in your system--and do something about them before someone else does. --David Wall
Topics covered: Security best practices, approached from the perspective of what can go wrong and what can be done about the problems. Specific coverage goes to all major services, including user management, FTP, HTTP, and firewalling.

Review
I read security books as reference materials, and this book is an awesome reference. Although the authors' primary focus is Linux, many of the terms, techniques, tools and discussions apply across all aspects of information security. (Security Bookshelf) (

I am a senior engineer for network security operations. I read "Hacking Linux Exposed" (HLE) to learn how adversaries compromise Linux hosts. HLE impressed me at every level. I highly recommend system administrators and security personnel read and heed this book's recommendations.
I wasn't a fan of Hacking Exposed, largely because its Unix section was a mere 50 pages of superficial, outdated, and obvious fluff. Hacking Linux Exposed makes up for that lack by digging into Unix in much more depth.Though it is modeled after the attack/countermeasure style of the original HE, this book includes a whole chapter of security measures at the beginning that you can implement instantly to get your machine locked down before getting into the nitty-gritty detail about other things in the hacker's arsenal.I was particularly enthralled with chapter 10, which talks about what the hacker will do after they have gained root access, from simple things like adding accounts to complicated issues like kernel modules, complete with source code. Chapter 7 includes some really wonderful examples of how the hacker can abuse networking protocols themselves, something I haven't seen covered in such depth before.The book is logically organized. The first part covers the way the hackers find and probe your machine. The second talks about getting in from the outside, be it network or physical. The third part talks about gaining additional priveleges, and the last part of the book is dedicated to mail, ftp, web, and firewalls. The appendicies are actually useful. They seem to have dropped the small 1-page case studies from the original book and replaced them with longer hacker-eye-views of real attacks which are an interesting read, and really tie the book together.This book is Linux specific in it's countermeasures, but I'd recommend this to any unix user. They do a good job of discussing differences between Linux variants as well, they don't just assume everyone has a RedHat box on their desk. Very refreshing.This book is great for both the theory and practical uses.
