Cloud services, such as SalesForce, Amazon Web Services and Microsoft® Azure, offer enterprise grade computing power to businesses of all sizes, without them having to invest in the hardware, software and staff usually needed to support equivalent on-premise services. Cloud Computing represents a major change to the IT services landscape, but it also introduces a different set of potential security risks, which need to be understood and addressed. Securing Cloud Services - A pragmatic approach to security architecture in the Cloud goes beyond the subject of generic Cloud security and, instead, offers a more detailed, architectural approach to securing Cloud services. It describes how security architecture processes may be used to derive a set of security controls to manage the risks associated with working in the Cloud. It uses a conceptual security reference model (SRM) to define a set of common security services, and then explains how these services can be delivered across the various Cloud service models in order to secure a Cloud-based service.
