XSS Attacks: Cross Site Scripting Exploits and Defense Review

XSS Attacks: Cross Site Scripting Exploits and Defense
Average Reviews:

XSS Attacks earns 4 stars for being the first book devoted to Cross Site Scripting and for rounding up multiple experts on the topic. The authors are synonymous with attacking Web applications and regularly share their vast expertise via their blogs and tools. However, XSS Attacks suffers the same problems found whenever Syngress rushes a book to print -- nonexistent editing and uneven content. I found XSS Attacks to be highly enlightening, but I expect a few other books on the topic arriving later this year could be better.
First, as Tadaka mentioned, ch 3 is the best written part of the book. In fact, the author of ch 3 should have written the entire book. There is a difference between an author of a tool, an author of a blog, and an author of a book. The author of ch 3 clearly knows how to make a clear argument over the course of a long stretch of pages (over 90) and carry the reader. Lucky for non-book-buyers, Syngress posted ch 3 for free on their Web site. You'll get a great foundation on XSS, and learn about CSRF and backdooring Flash and Quicktime.
In terms of readability, ch 2 wasn't bad. I liked trying out various Firefox extensions and the author's examples were good. I think ch 1 should be completely dropped. It mentions terms not defined until ch 2. The language is exceptionally rough, indicating zero editing was done. The DNS pinning examples in ch 5 were confusing; it doesn't help novice readers to discuss [...] and then use [...]. (I think that's an error.) I really didn't get as much from the book past ch 3 as I did from ch 3.
The major take-away from XSS Attacks is that one should never trust clients. Furthermore, far too many vulnerable capabilities exist in applications most people would never dream of fearing, like those that render .pdf or .swf. I really liked the point that browsers constantly interpret and "fix" broken HTML, sometimes to the detriment of the security world. I also liked reading how users can be duped by attacks against the integrity of data, such as adding or removing details of Web sites.
Right now, if you want to learn more about recent XSS attacks in printed form, this book is your main option. Last year I favorably reviewed Lance James' book, Phishing Exposed, which includes some of these techniques. Later this year one of the other book reviewers, Dafydd Stuttard, should be publishing The Web Application Hackers Handbook: Discovering and Exploiting Security Flaws. Syngress claims to be publishing Web Application Vulnerabilities: Detect, Exploit, Prevent by Steven Palmer in the fall. Hacking Exposed Web 2.0 by Himanshu Dwivedi is another option, but I find his security books to be poorly written. I highly recommend visiting the authors' blogs, since they cover a lot of the information in XSS Attacks.

Cross Site Scripting Attacks starts by defining the terms and laying out the ground work. It assumes that the reader is familiar with basic web programming (HTML) and JavaScript. First it discusses the concepts, methodology, and technology that makes XSS a valid concern. It then moves into the various types of XSS attacks, how they are implemented, used, and abused. After XSS is thoroughly explored, the next part provides examples of XSS malware and demonstrates real cases where XSS is a dangerous risk that exposes internet users to remote access, sensitive data theft, and monetary losses. Finally, the book closes by examining the ways developers can avoid XSS vulnerabilities in their web applications, and how users can avoid becoming a victim. The audience is web developers, security practitioners, and managers.*XSS Vulnerabilities exist in 8 out of 10 Web sites*The authors of this book are the undisputed industry leading authorities*Contains independent, bleeding edge research, code listings and exploits that can not be found anywhere else

Hacking: The Next Generation (Animal Guide) Review

I'm always skeptical about books that propose to cover such a vast spectrum of subjects, the book in question however does a wonderful job at explaining in plain english what is happening behind an attack, it unveils the possible motives and end result, and I personally found it a superb manuscript on what is happening today in the fields of hacking and social engineering.
On a more technical side it covers XSS attacks and blended exploits, again in plain english. Though the authors also throw some code in there to keep the techiest of us entertained, personally I found the inclusion of code somewhat unnecessary. 'Plain english' would suffice especially because I found that this would otherwise be the perfect book to hand to someone less techy who wants to know what is happening out there in the wild and to some extent what they need to look out for if they intend to be security conscious. Could they ignore the code? sure! will they? depends on the individual and his/her aversion to programming. It still keeps its five stars though, I cant fault a book for having too much information. The book also covers phishing attacks, that chapter was a very worth wile read. I hold no interest or curiosity in phishing attacks and after reading it I was surprised on what I had learned.
The chapters on social engineering and information gathering were very interesting as well. The authors made a clear effort to mention current online tools that attackers can use to acquire information on a target (may that be a person or a corporate entity) and go into deeper detail on how such an attack can develop into face to face contact with a target. The way the book is written makes it feel like a story, like one attack unfolds into another and that is really why this book is such good fun to read.
If there's something I can fault in this book its really its life span. You have to get it now for it to matter. In 2 years time all this will be old, stale news and at the speed things change in the IT/IS world its really quite inevitable. Social engineering will always be social engineering but the tools used to gather information will surely change.
