Security Architecture Improving In Cloud Computing Basic Services

Organizations should use from enterprise security architectures to secure their information assets. ýSecurity patterns are a good way to build and test new security mechanisms. Enterprise security pattern ýas an instance of model-driven architecture offers a solution to recurring information systems security ýproblems. In this paper, we present a model-driven enterprise security pattern called Secure SaaS., which ýthe organizations could apply to protect their information assets when using SaaS. On the other hand ýCloud Computing is a approach for the efficient use of computational resources. cloud delivers ýcomputing as a service. However, security concerns prevent many individuals and organizations from ýusing clouds. Second section of this paper focuses on the Security problem of Platform-as-a-Service ýý(PaaS) clouds including access control, privacy and service continuity while protecting both the service ýprovider and the user. Security problems of PaaS clouds are explored and classified. Countermeasures ýare proposed and discussed.
