Release 9.0 Ticketing: How to assign a security role to a ticketing application?

I know this is probably staring me right in the face but I cannot figure out how to do this.  I setup a new ticketing application (Technical Services Ticket Management) and I can view it as an option to select under user applications but there is nothing in the drop down for security role and I cannot save without selecting a security role.  I am attempting to do this for my user account, nafisher, and I am assigned the role TD-Enterprise: Administrator.  It seems that security roles would be associated with ticketing application(s) so they would be listed in the drop down but I'm cannot see where.
