What Snier is saying is that your database must be as secure as a bank is- and this is not by encorporating some third party to build a security megacenter right next to your bank, whether or not you man that megacenter isn't of issue.
No matter what, you'll always need physical police and security officers as you'll need virtual police and security officers -- but you still need a secure infrastructure in place.
I don't know how the AC above got from discussing his enhanced security posture to saying that infosec is dead or dying. That was some pretty good magic.
