In Today’s world with the engineering development, Internet connectivity has become a commodity product. With the rapid adoption of Web technologies such as blogging, online media sharing, social networking, it generates enormous quantities of data onto Internet servers. Like traditional infrastructure utilities, such as gas and electricity, “cloud” computing provide computing services via the internet on demand and pay per use access to a pool of shared resources namely networks, storage, servers, services and applications, without physically acquiring them. It saves managing cost and time for organizations and due to its flexible infrastructure, net centric approach and ease of access, the cloud computing has become prevalent. Today, security issue is the biggest hazards to moving services to external clouds. With cloud computing, data is stored and delivered over the Internet. The owner of the data does not have the control over the data even, does not know the location of the data and limited control over the data may incur various security issues and threats. Hence we discusses different security issues, its privacy and risk in a cloud and also suggests how to reduce the risk in cloud.
