Chris Hoff, one of the most respected voices on the topic of virtualization and cloud security, once told me in an interview that people should shut up about securing the cloud because, in his opinion, there's no such thing as cloud security.

"The notion that we're all running out to put our content and apps in some common [and secure] repository on someone else's infrastructure is unrealistic," Hoff, now director of cloud and virtualization solutions at Cisco Systems, told me.

Ariel Silverstone, a frequent contributor to CSOonline, has written about the myriad challenges of cloud security -- see Cloud Security: Danger (and Opportunity) Ahead -- including the problem of direct control: "Instead of having direct control over our concept of 'defense in depth,' we now have marginal control at best. Many times, such as with Amazon's EC2 service we have virtually no control, no pun intended. We sometimes do not have even the basic notification of something about to go wrong or something that has."

And yet we plunge into the cloud anyway, risks be damned.
