Proposed Abstract: This paper introduces a practical security model based on key security considerations by looking at a number of infrastructure aspects of Cloud Computing such as SaaS, Utility, Web, Platform and Managed Services, Service commerce platforms and Internet Integration which was introduced with a concise literature review. The purpose of this paper is to offer a macro level solution for identified common infrastructure security requirements. This model with a number of emerged patterns can be applied to infrastructure aspect of Cloud Computing as a proposed shared security approach in system developmentlife cycle focusing on the plan-built-run scope.

Conclusion of paper

- A well established dynamic security model for the infrastructure of cloud computing solution is essential.

-The dynamic model introduced in this paper offers a horizontallyand vertically configurable and policy based security approach covering all known security issues in a typical implementation of Cloud infrastructure

-Applying dynamic security policies using automated tools and processes contribute to the security of cloud computing in a positive manner: i.e.

-cost, -systems management-end user satisfaction.
