Nick Coleman recently addressed concerns that many companies are raising about data security in the cloud. Coleman writes, “Some people describe securing the cloud as a datacenter challenge, sometimes as a software issue, and sometimes as a data or device access issue. In reality, securing the cloud depends on working out where and how to apply those measures specific to your end user.”
He continues, “Indeed security services are continuing to develop, enabling a cloud delivery model and allowing us to have security increasingly delivered in cloud services. This will be applied to both the cloud infrastructures and to services in their own right. In essence the cloud model is evolving as one of the core models for delivering services.”
Coleman adds, “In considering cloud security, it is essential to understand what changes are involved in adopting cloud computing models. For example, multi-tenant infrastructures require isolation to be built in at the hypervisor, network, and storage layer. Other categories talked about less frequently include cloud governance and how to evolve assurance where data center inspection is not practical when you are scaling a service for a week or even a day. In looking at each of these, we have had to understand how we can deliver those elements in a cloud delivery model.”
