摘要：Cloud Computing represents a new computing model that poses many demanding security issues at all levels, e.g., network, host, application, and data levels. The variety of the delivery models presents different security challenges depending on the model and consumers' Quality of Service(QoS) requirements. Confidentiality, Integrity, Availability, Authenticity, and Privacy are essential concerns for both Cloud providers and consumers as well. Infrastructure as a Service (IaaS) serves as the foundation layer for the other delivery models, and a lack of security in this layer affects the other delivery models, i.e., PaaS, and SaaS that are built upon IaaS layer. Information Technology (IT) Security Risk Management is a critical task for the organization to protect against the loss of confidentiality, integrity, and availability of IT resources and data. Due to system complexity and sophistication of attacks, it is increasingly difficult to manage IT security risk. So this paper deals with Security at the application level in cloud.
