Hey there!

I believe he's trying to ask the following:

Why using a 3-tier scheme if with an SQL injection issue the attacker is able to "takeover" the DB, or with a Command injection control the App Server... and/or some kind of vulnerability like the one for Apache you can play with the Web Server infra?

Maybe he's wondering that... don't really know..

cheers, Nahu.-
