The cloud is clear as mud

The Economist opines that the world is flirting with recession and IT may suffer; which in turn will hasten the move to “cloud computing”, which in a pithy distillation is described as “a trade-off between sovereignty and efficiency”.

Computing as a borderless utility? Whereas most privacy laws assume data resides in one place…the cloud makes data seem present everywhere and nowhere.

In a recent post Steve differentiated between security OF the cloud and security IN the cloud. This led us to an analysis of cloud computing as it is currently offered by Amazon AWS, Google Apps and Zoho.

From a risk perspective, security of content IN the cloud is essentially considered your problem by Amazon whereas Google and Zoho say “trust in me, just in me”. When pressed, Google says “we do not recommend Google Apps for content subject to compliance regulations” but is apparently working to assuage concerns about access control.

However moving your data to the cloud does not absolve you from responsibility on who accessed it for what purpose — the main concern of auditors everywhere.

How now?

At the present time, neither Google nor Zoho make any audit trail available to subscribers while at Amazon it’s your problem. We think widespread adoption by the business community (and what of the federal government?) will require significant transparency to provide visibility. This is also true for popular hosted applications like Intuit Quickbooks and Salesforce.

As Alex notes “…in order to gain that visibility, our insight into Cloud Risk Management must include significant provisions for understanding a joint ability to Prevent/Detect/Respond as well as provisions for managing the risk that one of the participants won’t provide that visibility or ability via SLA’s and penalties.”

Clear as mud.
