I'm on to an R & D task for testing the
security vulnerabilities that can happen in a web application. I want use an
open source tool.
There are many type of vulnerabilities like
Cross Site Scripting,
Denial of Service,
Session Setting etc. So, I would like to have a best fit cross platform tool to do penetration testing in a best possible way.
I've gone through Security testing of web application and Open source web security testing tools, and I found it useful. But, as it was posted a year ago, I would like to have an updated answer. Thank you.
