Securing Cloud Services – A pragmatic guide gives an overview of security architecture processes and explains how they may be used to derive an appropriate set of security controls to manage the risks associated with working in the Cloud. The book: - Introduces the concepts of Cloud computing and the associated security threats; - Explains key security architectures and how they can be applied to Cloud services; and -Covers security considerations for the different Cloud service models: IaaS (Infrastructure as a Service), PaaS (Platform as a Service), SaaS (Software as a Service) and FaaS (Function as a Service). Cloud computing represents a major change to the IT services landscape, but it also introduces changes to the risk landscape, which need to be understood and addressed. The flexibility of Cloud computing does not come without compromise or risk. Security remains a major concern for CIOs (chief information officers) considering a move to Cloud-based services. This book gives organisations pragmatic guidance on how to achieve consistent and cohesive security across their IT services – regardless of whether those services are hosted on-premises, on Cloud services or using a combination of both. This guidance in Securing Cloud Services – A pragmatic guide is provided through the application of a Security Reference Model to the different Cloud delivery models – IaaS, PaaS and SaaS – and also considers the changes in approach required to work securely with the newer FaaS model. Part 1 introduces the concepts embodied within Cloud computing, describes the associated security threats and lists some of the leading industry initiatives dedicated to improving the security of Cloud services. Part 2 introduces security architecture concepts and a conceptual Security Reference Model. This model is then applied to the different Cloud service models to show how the conceptual security services within the reference model can be delivered for each Cloud service model.
