Cloud Standards Now!?
July 27th, 2010 By Ron KnodeWouldn’t it be wonderful if we could simply point to cloud standards and claim that such standards could reliably lubricate government adoption of safe, dependable, accreditable cloud computing?! Sadly, we cannot. At least, not yet.
And, this fact is as true for commercial adoption of cloud computing as it is for government adoption. It is also the subject of this month’s question in the Mitre Cloud Computing Forum for Government.
Well, we don’t have the standards, but what we do have is the collective sense that such standards are needed, and the energy to try to build them. Furthermore, while the “standards” we need do not yet exist, we are not without the likely precursors to such standards, e.g., guidelines, so-called best practices, threat lists, special publications, and all manner of “advice-giving” items that try to aim us in the right direction (or at least aim us away from the very wrong direction). In fact, we have so many contributors working on cloud standards of one kind or another that we are in danger of suffering the “lesson of lists” for cloud computing.
Nevertheless, given our desire to reap some of the benefits of cloud computing, should we not try to accelerate the production, publication, and endorsement of cloud computing standards from the abundance of sources we see today?
Wait a minute! Standards can be a blessing or a curse. On the one hand, standards make possible reasonable expectations for such things as interoperability, reliability, and the assignment and recognition of authority and accountability. On the other hand, standards, especially those generated in haste and/or without widespread diligence and commentary, can bring unintended consequences that actually make things worse. Consider, for example, the Wired Equivalent Privacy (WEP) part of 802.11 or the flawed outcomes and constant revisions for the PCI DSS (remember Hannaford and Heartland!?).
Furthermore, even when standards are carefully crafted and vetted with broad and intensive review, they can still be misinterpreted and misapplied by users, leading to surprising outcomes such as the USB device flaws that showed up in products with FIPS 140-2 certified modules. Even the best standards require an informed and sensible application on the part of users.
What we seek are standards that lead us into trusted cloud computing, not just “secure” cloud computing or even “compliant” cloud computing. Ultimately, any productive stack of standards must deliver transparency to cloud computing. Otherwise, cloud consumers will remain trapped in the never-ending cycle of cloud security claims, with no easy way for individual and independent validation, and cloud vendors will remain stymied by having no regular way to demonstrate their conformance without a lot of technical mumbo-jumbo or expensive and time-consuming third party intervention.
Simply having cloud standards just to have standards does not bring any enterprise closer to the promised payoffs of the cloud.
Let’s consider the possibility that different categories of standards, or tiered standards, may be required to cover all of the important use cases for government and commercial use. Not every cloud or every cloud market need necessarily be encumbered with every cloud standard.
Finally, let’s consider also what it might take to demonstrate compliance with standards. For example, it is unlikely that “whole cloud” compliance will be effective or efficient across the board. A standard that is more trouble than it’s worth is not going to be very helpful at all.
So, let’s proceed with all deliberate speed through some of the worthy efforts ongoing, but not declare success merely for the sake of an artificial deadline or competitive advantage. The cloud definition and certification efforts sponsored by NIST and GSA, the security threat and guidance documents authored by the Cloud Security Alliance, the cloud modeling work of the OMG, the cloud provider security assertions technique proposed by Cloudaudit.org, and the CloudTrust Protocol that extends SCAP notions and techniques to reclaim transparency for cloud computing — all of these efforts certainly hold promise for accelerating the adoption of cloud computing for government and industry.
Let’s push and participate in the actions of these and other groups. Ask questions, experiment, build prototypes, consider all manner of outcomes, and seek extensive and deliberate peer review. Standards that survive such a process can be endorsed. But, like fine wines, cheeses, (and even thunderstorms), “We will accept no cloud standard before its time.”
