Recently I discussed Virtualizing Business Critical Applications and security, which includes availability, confidentiality, and integrity. However, that discussion was more about visibility into the environment for security operations. I purposely left off the discussion of gaining integrity and confidentiality of the data housed within those business critical applications.
When you read many blogs and articles on cloud security, writers such as myself often mention jurisdictional issues as a big problem. Nor is the ability to Audit clouds the only problem. Yet both of these are huge issues for clouds today, but fundamentally, is the cloud flawed from a security point of view or are there plenty of security mechanisms available?
With the diversity of cloud’s available today, data being sent from one to another could appear to be a hodge-podge of security. As one colleague put it recently when I asked what he was expecting to maintain integrity of data in motion between clouds:
“… what kind of kludge can things end up being when you have multiple connections to multiple hybrid clouds all doing different things” — Steve Beaver
So how does data transfer between the clouds? Is it a kludge? or can it be done using a uniform security policy, procedures, and protocols while maintaining Integrity and Confidentiality and auditability?
I just finished reading, yet another Multi-Tenancy Design/Overview that claims to be secure or trusted. While I will agree that this particular design does cover Availability and some GRC (Governance, Regulatory, and Compliance) it is severely lacking in Integrity and Confidentiality. The design even went as far as saying the cloud/virtual administrator requires “COMPLETE VISIBILITY.” I was really taken aback by those words. Why does an administrator need ‘COMPLETE VISIBILITY?’ Which leads me to the question is Integrity and Confidentiality possible within any cloud or virtual environment? Or is it purely based on TRUST?
If so this is an appalling state of virtual and cloud environment security.
