I'm always chocked by comments like this:
So let's start with the nonsensical idea that your cloud infrastructure is secure.
It is 2009, and the whole idea of any secure infrastructure is just totally naive..
Your cloud infrastructure is likely secured with respect to some requirements, but it's just as certain to be insecure for other requirements. The cloud has nothing to do with this. Every infrastructure on the planet is secure for some requirements and insecure for others.
|If your cloud provider refuses to answer any specific question about their security architecture related to your security requirements, run—don't walk—away from that vendor.|
