Developer's Guide to Web Application Security

When I came across this book on the O'Reilly website I was immediately interested, as web applications are becoming more and more prevalent. And other than thinking it covered methods of securing web applications I had no preconceived assumptions. My main aspiration for this book was to give me better awareness of security in the area of web applications and to provide me with some tools. After having read this book I can say that it has done both. Each of the chapters in this book seem to follow a pattern of first defining the topic, second giving real world examples, and finally providing the reader with solutions. The book begins by providing a history of the hacking methodology and defining the various types of hacking. It was interesting to learn about some of the various hacks and hackers. For example, I had no idea Steve Jobs (Apple Computers) used to be a hacker. In chapter two the author discusses what he calls a "Code Grinder", and how to not become or produce a code grinder. A code grinder is someone who works in a highly regulated environment where creativity is discouraged. I found it interesting that a code grinder environment typically produces more unsecure code then an environment that is open and promotes creativity. Chapter three discusses the risks associated with mobile code. Chapter four covers vulnerable CGI scripts and introduces the reader to some tools such as Nikto and Web Hack Control Center to scan your website to find vulnerabilities. The author goes on to discuss the issues faced by the various CGI scripting languages, and then provides an outline of rules to writing secure CGI scripts. Chapter five covers hacking techniques and tools. This section gets you into the mind of a hacker, what are their goals, how are those goals achieved and what tools do they use. In chapter six the topic is "Code Auditing and Reverse Engineering." This chapter I found exceptionally interesting and helpful. The author takes you through various types of vulnerabilities and with each weakness explains how it affects each of the more popular programming/scripting languages. And to take it a step further the author also provides the reader with the functions/methods for each programming/scripting language that are vulnerable to attack and then explains either how to use those functions securely or gives an alternative function/method that is more secure. Chapters seven through ten cover securing code in specific languages; Java, XML, ActiveX, and ColdFusion. Chapter eleven discusses developing security enabled applications using such technologies as PGP, SSL, and PKI. Finally in chapter twelve the author wraps up the book by taking the reader through creating and working with a security plan. CONCLUSION -- I found this book to be interesting and a good read. I plan to make use of some of the tools it introduced in hardening applications I work with and develop. And as I mentioned before, the chapter on code auditing w

With the increasing number of incidents of crime that is occurring on the world wide web it behooves every programmer to become fluent in all aspects of information security. This book provides a great overview of the various methods a hacker uses to penetrate various forms of web architectures. The author's goals it seems was to cover a broad subject by touching on all important aspects of securing a website. Throughout the book a hacker mindset is presented and how to design your website to overcome the tools and tricks of the hacker. For instance in many of the chapters the manner of attack that a hacker would use to exploit a piece of technology is covered. Overall I believe this book to be a good introduction to the field of securing websites. Since security in of itself is such a broad subject and the Internet is also a broad subject it is unfair to expect one book to cover all aspects of a complex and dynamic environment
