Hi Bart,

thanks for the link to the article. To the best of my understanding,
the guys suggest to authenticate the devices first and only then
authenticate the users who use the devices in order to get access to a
corporate service. They also mention in the presentation the current
trend of moving corporate services into the cloud. But I think this is
not about the devices from which that cloud is build of. Isn't a cloud
first build out of devices connected via IB and then users (and their
devices) are provided access to the services of that cloud as a whole?
If a malicious user already plugged his device into an IB switch of a
cloud internal infrastructure, isn't it game over anyway? Can't he
just take the hard drives instead of mapping them?
