ASP.NET MVC - .NET Security Testing Framework?

As a new tester I am currently using MS Web Test in automation of verification/validation/load/ordering tests.
Does anyone here familar with how to do testing(asp.net MVC app.) on its security side in a SYSTEMATICAL way - generate a bunch of lists(receipts) of security testing on ASP.NET application? By creating these security test cases against my app.(ideally still using .NET framework) and passing these test cases - then I can claim(at least partially) that my app. is secure in these areas.

Thanks for anyone who can show me the direction!
