Think of it this way, what ever programming problems you put in front of
your mainframe will expose your mainframe. So if .net or the code
running in .net have bad code (input validation not checked, ...) then
that will pass directly back to the mainframe and all of the controls on
the mainframe will be bypassed because of the trust it will have with
the frontend app.
The application control tests (i hope you mean within the code and
externally through code review) will help a lot with your concerns,
however since you can't control the code for .NET & AG communicator you
should assume you can't trust anything going to-from those environments.
Good luck!
