I would like to know whether there are any free tools available which can be used to test security vulnerabilities in a rails app. I came across skipfish, which I found was not very intuitive in its report. Are there any similar tools available?
Update
I've found a tool, ZAP, which can be used for doing penetration testing for any Web applications. You can easily automate it by integrating it with testing tools such as Selenium. This looks really cool and has many features and easy to use too.
