Cloud computing separated into three layers: the infrastructure layer, platform services layer, application layer software.
The security problems and challenges of these layers are different. Data center construction, physical security, network security, transport security and system security are the key point for IaaS. However, for PaaS, data security, data availability, computing availability and the problems of disaster and recovery are paid more common. But mostly these issues fall into two broad categories: Security issues faced by cloud providers (organizations providing software-, platform-, or infrastructure via the cloud) and security issues faced by their customers [4]. Data security is encrypting the data as to ensure that suitable policies are imposed for data sharing. Additionally, resource allocation and memory management algorithms have to be protected. Sometime, the supplier should...
