OWASP Code Review Guide is a technical book written for those responsible for code reviews (management, developers, security professionals). The primarily focus of this book has been divided into two main sections. Section one is why and how of code reviews and sections two is devoted to what vulnerabilities need to be to look for during a manual code review. While security scanners are improving every day the need for manual security code reviews still needs to have a prominent place in organizations SDLC (Secure development life cycle) that desires good secure code in production.
Second sections deals with vulnerabilities. It is based on the poplar OWASP 2013 top 10. Here you will find most of the code examples for both on what not to do and on what to do. A word of caution on code examples; Perl is famous for its saying that there are 10,000 ways to do one thing. The same is true for C#, PHP and Java or any other computer language. Now add in "Object-Oriented Programming" and if we are using design patterns or even what designs patterns are being used and sample code becomes very “iff” in what to write. We tried to keep the sample code so code reviews can see red flags and not “do it my way or else”.
The last section is the appendix. Here we have content like code reviewer check list, etc. of items that really don’t flow in book form but needed to be included to make the code review guide compete.
