摘要:

云安全问题从云计算技术发展之初就被普遍认为是制约其发展的核心因素。首先讨论了云计算系统中的不安全因素,同时也对云计算技术带来的安全改善进行了分析,对云安全性进行了深入剖析。指出云计算系统安全取决于现有安全策略的正确部署,只要与云提供商签署适当的安全契约,云计算系统并不比本地环境的安全风险更大。最后对于保证云计算系统安全问题,分别从云提供商以及云用户两个角度给出了相应的安全策略建议。

Abstract:

Cloud security has been widely considered as the key factor restricting its development since the cloud computing technology emerged.The insecure factors of cloud computing system and the secure factors which cloud computing brings were presented and discussed.It was pointed out that cloud security depended on the validate deployment of the security policy.Cloud computing system is not less secure than native environment,as long as the right agreement is signed with cloud provider.Finally,the proposal of security policy was provided from both the cloud provider domain and the cloud user domain to ensure the security of cloud computing system.

Key words: cloud computing, cloud security, virtualization, cloud provider domain, cloud user domain
