CodeIgniter PHP NYC - Web Application Security

As discussed we are going to do a Security focused meetup. Web applications are of course the primary focus of the group (and CI / PHP) but feel free to bring other things to the table.

We'll start with a quick introduction to web application's and a general security model and progress into a general discussion of available security libraries, what we would like a security library to contain. Time and attendance permitting we can even mock up some basic libs for use.
