Abstract: Cloud computing is a word that delivering hosted service over the internet. Cloud computing has been ideate as the next generation architecture of IT enterprise because of it’s provides ubiquitous network, cost reducing, flexibility and scalability to users. Now days with the fast growing of cloud computing technology introduces new more vulnerabilities so security is considered to be one of the most critical aspect in clod computing environment due to the confidential and important information stored in the cloud. As per AMAZONE EC2 service case study it is possible to identify the particular target VM(virtual machine) in internal cloud infrastructure and then placed new VM with targeted VM and extract confidential information from targeted VM on same physical machine called as simple side channel attack. This paper introduces how to avert the side channel attack in cloud computing. This is accomplished by using combination of Virtual firewall appliance and randomly encryption decryption (using concept of confusion diffusion) and provide RAS (Reliability, Availability, and Security) of client’s data or information. 
Keywords: Cloud computing, side channel attack, Amazon EC2 service case study, virtual firewall appliance, randomly encryption decryption.
