Preventing Cache Based Side-Channel Attacks for Security in Cloud over Virtual Environment

S. Vengadesan | B. Muthulakshmi ^[2]

Abstract: Cloud computing is a unique technique for outsourcing and aggregating computational hardware needs. By ing the underlying machines Cloud computing is able to share resources among multiple mutually distrusting clients. While there are numerous practical benefits to this system, this kind of resource sharing enables new forms of information leakage such as hardware side-channels. The usage of CPU-cache based side-channels in the Cloud and how they compare to traditional side-channel attacks. New techniques are necessary to mitigate these sorts of attacks in a Cloud environment, and specify the requirement for such solutions was developed. The security issues faced by cloud service providers and the service issues faced by the cloud customers are analysed. In the existing system, providing security in cloud requires a huge amount of money based on the service on demand in cloud environment. The extensive use of virtualization in implementing cloud environment brings unique security providence for the cloud customers and all other resellers & subscribers of a public cloud service access. In the proposed system, an effective firewall security has been implemented for blocking and filtering the unwanted requests from the clients before the request reaches the virtual machine destination. During the request processing, if the user requests the high level data from the cloud, the data can be provided against payment.
