Thank you.
It seems that the early hardware will be connected to cloud hardware.
That does make the cloud host a target, from inside or outside.

Black boxes ;-)

So it seems prudent to tighten up cloud OS systems and policy yesterday
knowing how long it takes to retire a cryptographic method and how quickly
hardware can be connected to a cloud system.
Key management will be interesting.

Thank you
