A Conceptual Architecture for Securing Public Cloud:Moving from Trust toward Security

Cloud computing is next generation era of IT enterprise, which provide services like resource pooling, on demand and metered service. It provides the burden free environment for the consumer, to get rid of resource management. It also shifts all digital assets (data and application) to the centralized large datacentre. These datacentre can be on- premise or off-premise cloud service provider, depending on the nature of cloud service consumer i.e. either general public or small scale enterprise. Such type of cloud consumers need are generally fulfilled by off-premises clouds which are handled by third party cloud service provider, which increases the security threat for identity and access, data privacy and security. Thus cloud consumer has to keep a high level of trust on cloud provider. Thus the conceptual architecture for securing the public cloud is the concept which will help to provide a high level of security in spite of trust for the public cloud. This work proposes a third party “Special Security Agent (SSA)” which will be a government body or certified authority, for maintaining the security and identity of digital asset for both cloud provider and consumer.
