Version 3 of the OWASP testing guide is now available!
This project’s goal is to create a "best practices" web application penetration testing framework which users can implement in their own organizations and a "low level" web application penetration testing guide that describes how to find certain issues.
Thanks to all that put in the work to make this guide possible. I think it is a very useful resource for all the various types of security professionals out there. Download the OWASP Testing Guide v3 (pdf) now! Also, during the OWASP EU Summit in Portugal, there was a presentation on the testing guide. Enjoy!
