Hi! 2010/4/19 pand0ra <pand0ra.usa () gmail com>
Question: You are doing code review and come across a javascript application that does not do input validation. Would you have the developer go back and write in input validation? If so, why? If not, why?
When this is a pure JS app, then validation should be done where necessary. Especially when a lot of "business logic" is located in the javascript client. When the JS is just to make it look fancy and the real logic lies on the server, you'll probably be fine doing just server side validation. just my 2 c -- Bye, Patrick Cornelißen http://www.openprojectguide.org http://www.pcornelissen.de http://code.google.com/p/gloudy/ ------------------------------------------------------------------------ This list is sponsored by: Information Assurance Certification Review Board Prove to peers and potential employers without a doubt that you can actually do a proper penetration test.
