Why This Book? If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but not the enemy, for every victory gained you will also suffer a defeat. If you know neither the enemy nor yourself, you will succumb in every battle. —Sun Tzu, Art of War Translation and commentary by Lionel Giles (part of Project Gutenberg) "Golly Gee!" you might be thinking. "Why write a book on hacking? You'll just encourage them to attack more!" I respect your concern, but unfortunately there are some flaws behind this logic. Let's face it—the malicious attackers have all the information they need to do all kinds of nasty things. If they don't have the information now, they can get it easily enough on the Internet through a variety of Web sites, mailing lists, and newsgroups devoted to hacking, using a variety of the Web sites we discuss in Chapter 13, The Future, References, and Conclusions. Experienced attackers often selectively share information with new attackers to get them started in the craft. Indeed, the communication channels in the computer underground among attackers are often far better than the communication among computer professionals like you and me. This book is one way to help make things more even. My purpose here is not to create an army of barbarian hackers mercilessly bent on world domination. The focus of this book is on defense, but to create an effective defense, we must understand the offensive tools used by our adversaries. By seeing how the tools truly work and understanding what they can do, not only can we better see the needs for good defenses, but also we can better understand how the defensive techniques work. This book is designed for system administrators, security personnel, and network administrators whose jobs require them to defend their systems from attack. Additionally, other curious folks who want to learn how attackers work and techniques for defending their own systems against attacks can benefit. The book includes practical recommendations for people who have to deal with the care and feeding of systems, keeping them running and keeping the bad guys out, ranging from home users to operators Chapter 1.

With this understanding, we can work to create an environment where effective defensive techniques are commonplace, and not the exception. As good ol' Sun Tzu said, you must understand your enemy's capabilities and your own. For each offensive technique described in this book, we'll also describe realworld defenses. You can measure your own security capabilities against these defenses to see how you stack up. Where your policies, procedures, and technologies fall short, you can implement appropriate defenses to protect against the enemy. And that's what this book is all about: Learning what the attackers do so we can defend ourselves. Why Cover These Specific Tools and Techniques? There are thousands of different computer and network attack tools available today, and tens of thousands of different exploit techniques. To address this flood of possible attacks, this book focuses on particular genres of attack tools and techniques, examining the most widely used and most damaging tools from each category. By learning in depth how to defend against the nastiest tools and techniques in each category, we will be defending against all related tools in the category. For example, there are hundreds of methods available that let an attacker hide on a machine by transforming the operating system itself, using tools called rootkits. Rather than describing each and every individual rootkit available today, we analyze in a greater level of detail some of the most powerful and widely used rootkit tools in Chapter 10, Phase 4: Maintaining Access. By learning about and properly defending against these specimens, you will go a long way in securing your systems against other related rootkit attacks. In the same way, by learning about the most powerful tools in other categories, we can design and implement the most effective defenses. How This Book Differs In recent years, several books have been released covering the topic of attackers and their techniques. Some of these books are well written and quite useful in helping readers understand how attacks work and highlighting defenses. Why add another book to the shelf addressing these topics? I'm glad you asked. This book is focused on being different in several ways, including these: • Being more like an encyclopedia instead of a dictionary. Other books in this genre cover thousands of tools, with a paragraph or page on each tool. As described in the previous section, this book focuses on understanding each category of tool in much more depth. Therefore, whereas other books act like fantastic dictionaries of attack tools and defenses, this book aims to be more of an encyclopedia, describing the attack process in more detail and providing the overall architecture of attacks. By covering each category of attack tool and the overall attack architecture in more detail, we can better understand the appropriate defenses. But, the book isn't designed to be just an encyclopedia. We don't want this book to be merely a giant tome on your shelf Chapter 1. Introduction Page 4 Return to Table of Contents Chapter 1.

Instead, we aim to provide the material in an interesting and educational manner, helping bring readers up to speed with the myriad of attacks we face and real-world methods for handling them in an effective manner. • Presenting a phased view of attacks. Other books present a view of how attackers gain access to systems, focusing on the penetration portion of an attack. Although gaining access is an incredibly important element of most attacks, our adversaries do much more than simply gain access. Once access is gained, most attackers manipulate the system to maintain access and work hard to cover their tracks. This book covers the attack sequence end-to-end by presenting a phased approach to attacking, so we can cover defenses at each stage of a siege. Most attacks follow a general outline that includes reconnaissance, scanning, gaining access, maintaining access, and covering the tracks. This book describes each phase in detail. • Covering scenarios for how the tools are used together. The tools used by attackers are a little like building blocks; each one fills a specific (but limited) purpose. Only by seeing how attackers build complete attacks out of the little blocks can we understand how to best defend ourselves. Sophisticated attackers take individual building blocks of tools and combine them in creative ways to devise very elegant attacks. This book describes how the tools are used together with its phased view of an attack. Additionally, Chapter 12, Putting It All Together: Anatomy of an Attack, presents several scenarios describing how these tools are used together in the wild to undermine systems. • Using analogies to illustrate the underlying computer concepts. Throughout the book, I have used analogies to highlight how various technologies work. Although some of the analogies are certainly cheesy, I hope they make the material more interesting and accessible to readers.
