Management process based cloud service security model

Security problem is considered as one of the greatest challenges in providing cloud computing service. It´s essential for success in cloud services business. Existing researches focus on providing security technologies, rather than business features such as services stability, continuity and availability. To fulfil the business requirements, this paper presents a cloud-based security service management processes model. And a new mapping method is used to get assets and processes mapping matrix. Then the dynamic computational model for cloud security risk can be evaluated. By this means, cloud computing services will maintain high availability and continuity; moreover, it satisfies the cloud computing platform and management system security requirements.
