Hackers Beware starts with a roadmap of the various areas of hacking but quickly delves into the details of how specific attacks work and how to protect against them. Since most attacks we hear about either occur or are perceived to come from hackers, people are very interested "in how they do that" - the techniques hackers use to break into systems. Hackers Beware is unique in that it gives specific exploits, exactly how they work and how to protect against them. This book will help readers understand what security threats they are up against and what they need to do to protect against them. Some books cover this from a high level but do not get into the details of specific exploits and cover it in a case by case fashion. This book will cover the complete picture. It will not only describe how an exploit works but present the signature of the attack, what to look for on a network and how to protect against it.

Product Description
Amazon Review
Cole's didactic style is largely conversational, embracing the fact that most computer exploits can be conveyed as stories about what hackers want and the steps they take to achieve their goals. He punctuates his prose passages with line drawings that clarify what gets passed among the machines involved in an attack, and pauses frequently to show programs' user interfaces and passages from their logs. Cole explains all the jargon he uses--a characteristic that alone distinguishes this book from many of its competitors. --David Wall
Topics covered: What motivates black-hat hackers, and the technical means they use to go about satisfying their ambitions. General attack strategies--spoofing, password cracking, social engineering, and buffer overflows, among others--are explained, and the tools used to carry them out are catalogued. The same goes for defensive tools and practices.

The message of "Hackers Beware" is clear: prevention is preferred, but detection is mandatory. To discover intrusions, one must understand the tools and tactics of the adversary. To this end, "Hackers Beware" devotes chapters to information gathering, spoofing, session hijacking, denial of service, buffer overflows, password security, access preservation, and log cleaning. Some of the material in these chapters is based on the "practicum" required of SANS students.
My favorite section, without doubt, was chapter 17: "Other Types of Attacks." It features many valuable essays by SANS students on BIND NXT exploitation, cookie-based overflows, SNMP enumeration, and other topics.
Publishing student material has its drawbacks, however. "Hackers Beware" is repetitive, a sin given the book's page count (778). Why include yet another explanation of buffer overflows in chapter 14, for example, when a whole chapter (7) already discusses them? (Actually, Brent Hughes' work in chapter 14 is more enlightening!) Furthermore, the "fundamentals" of UNIX and NT chapters are much less informative compared to Ed Skoudis' chapters in "Counter Hack."
I also recommend New Riders help the author overcome his addiction to "three phrase sentences," such as "Now the Internet is very popular, and everyone is using Linux because it is powerful and inexpensive, so the number of people beating on the system is very high." (p. 480.)
Future editions should reduce the number of vulnerabilities described in favor of more thorough explanations of sample exploits. For example, a virtual reprint of cDc's advisory on a NetMeeting weakness teaches me very little; providing background on the coding, system calls, and principles of this exploit is more useful. I would also pare the student-based material down to the essential core, removing generic material discussed elsewhere.
I'd almost buy "Hackers Beware" for chapter 17 alone, so I'm sure security professionals will find many reasons to enjoy this book.
(Disclaimer: I received a free review copy from the publisher.)
The book details how attackers gain access into different type of operating systems and hardware platforms. More importantly, Cole describes countermeasures to use to defend against the various types of attacks and exploits he describes.
Overall, an excellent reference for anyone needing to understand how hacking works and how to defend against them.
Cole discusses exploits against Linux, UNIX, Windows, and Windows NT and the myriad of programs (password crackers, network sniffers, back door programs, etc.) designed to break into other people's systems. Each program is described in full and what it does. Cole also offers suggestions and solutions in various chapters to keep unauthorized users from accessing various systems.
While you will never be 100% safe from an "attack," Cole's book offers ways to keep your system from being attacked or ensure that the chances of it actually happening remain remote, or the "damage" from such attacks stays minimal.
