The Web Application Hacker's Handbook: Discovering and Exploiting Security Flaws

The Web Application Hacker's Handbook: Discovering and Exploiting Security Flaws. This book is a practical guide to discovering and exploiting security flaws in web applications. The authors explain each category of vulnerability using real-world examples, screen shots and code extracts. The book is extremely practical in focus, and describes in detail the steps involved in detecting and exploiting each kind of security weakness found within a variety of applications such as online banking, e-commerce and other web applications.

The topics covered include bypassing login mechanisms, injecting code, exploiting logic flaws and compromising other users. Because every web application is different, attacking them entails bringing to bear various general principles, techniques and experience in an imaginative way. The most successful hackers go beyond this, and find ways to automate their bespoke attacks. This handbook describes a proven methodology that combines the virtues of human intelligence and computerized brute force, often with devastating results.

The authors are professional penetration testers who have been involved in web application security for nearly a decade. They have presented training courses at the Black Hat security conferences throughout the world. Under the alias "PortSwigger", Dafydd developed the popular Burp Suite of web application hack tools.

"If you have an interest in web application security, I would highly recommend picking up a copy of this book, especially if you’re interested in being able to audit applications for vulnerabilities".
—Robert Wesley McGrew, McGrew Security

Reader'a Review :

This is the most important IT security title written in the past year or more. Why? Custom web applications offer more opportunities for exploitation than all of the publicized vulnerabilities your hear about combined. This book gives expert treatment to the subject. I found the writing to be very clear and concise in this 727 page volume. There is minimal fluff. While everything is clearly explained, this is not a beginners book. The authors assume that you can read html, JavaScript, etc... Usually with a book like this there are a few really good chapters and some so-so chapters, but that's not the case here. Chapters 3-18 in this book rock all the way through. Another huge plus is the tools in this book are free.

The first few chapters provide context and background information. Chapter 3 on Web Application Technologies provides particularly useful background info. The next 666 pages of the book are all about attacking the applications.

There next five chapters cover mapping application functionality, client side controls, authentication, sessions, and access controls. The coverage is comprehensive. I'm not new to these topics, but I learned so much in every chapter. The depth of coverage is amazing.

The next six chapters are the heart of this book. They cover injection, path traversal, application logic, XSS and related attacks, automating attacks, and information disclosure. You'll find full treatment of attacks we're all familiar with like SQL injection and cross site scripting as well as many that most of us haven't heard of before. The danger is real and these chapters need to be read.

The final next four chapters cover attacks against compiled applications, application architecture, web servers, and source code. The final two chapters are more useful as a quick reference. They provide an overview of the tools covered throughout the book and describe attack methodology discussed throughout the book for exploiting each technology.

This book scores five easily based on the relevance and value of the information.
