Why do you upgrade your management systems asynchronously to your 
applications?  You bring this on yourself.

Why do you access mission-critical systems that are provably insecure 
from systems that also have internet access?

If it's not mission-critical, then you should explain why you haven't 
dumped that vendor yet for shipping insecure software - an insecurity 
that is very easy to mitigate by them, should they have chosen to.
