As a new user of DNN, I am somewhat concerned about blog entries pointing to security issues primarily associated with third party applications.  Since many DNN applications utilize some number of third party modules, how does one build a web site and represent that it is secure - or at least, as secure as it would be if the web site were build in any other fashion?.  Furthermore, if a vulnerabiity is identified, what certainty can there be that a third party will react quickly to repair the module?  Does anyone have any definitive data that indicates if this is a real problem or not?  Should a potential recipient of a DNN/Third party created web site be concerned about security issues any more so than other users? 

As someone who is considering using DNN to build web sites for my clients, should I expect my clients to object to the choice of DNN because of these perceived security issues?  How do you address these issues with your clients?
