Cloud computing is a technology that uses the internet and central remote servers to maintain data and applications. Cloud computing allows consumers and businesses to use applications without installation and access their personal files at any computer with internet access. This technology allows for much more efficient computing by centralizing storage, memory, processing and bandwidth. Fast and reliable connectivity is a must for the existence of cloud computing. Cloud computing is clearly one of the most enticing technology areas of the current times due to its cost-efficiency and flexibility. However, despite the surge in activity and interest, there are significant, persistent concerns about cloud computing that are impeding the momentum and will eventually compromise the vision of cloud computing as a new IT procurement model. There are numerous security issues for cloud computing as it encompasses many technologies including networks, databases, operating systems, virtualization, resource scheduling, transaction management, load balancing, concurrency control and memory management. Cloud computing raises privacy and confidentiality concerns because the service provider necessarily has access to all the data, and could accidentally or deliberately disclose it or use it for unauthorized purposes. The complexity of security is greatly increased when data is distributed over a wider area or greater number of devices and in multi-tenant systems that are being shared by unrelated users. In this regard, the war for the future of security and privacy issues in the cloud is just beginning. Tough analysts of cloud security are gaining new credibility. For instance, a new way of auditing specifically designed for the cloud industry is evolving. Overall, it is fair to say that privacy and security issues related to the cloud industry are undergoing political, social, and psychological metamorphosis. This paper discusses the types, layers, data security and privacy issues and some propositions for security in cloud.
