A REVIEW ON SECURITY AND PRIVACY ISSUES IN CLOUD COMPUTING

Cloud computing is an upcoming paradigm that offers tremendous advantages in economical aspects, such as reduced time to market, flexible computing capabilities, and limitless computing power. To use the full potential of cloud computing, data is transferred, processed and stored by external cloud providers. However, data owners are very skeptical to place their dat a outside their own control sphere. Cloud computing is a new development of grid, parallel, and distributed computing with visualization techniques. It is changing the IT industry in a prominent way. Cloud computing has grown due to its advantages like sto rage capacity, resources pooling and multi - tenancy. On the other hand, the cloud is an open environment and since all the services are offered over the Internet, there is a great deal of uncertainty about security and privacy at various levels. Proposed wo rk aims to address security and privacy issues threatening the cloud computing adoption by end users. Cloud providers are mindful of cloud security and privacy issues and are working hardly to address them. Few of these threats have been addressed, but man y more threats still unsolved. Proposed work focused on cloud computing security and privacy threats, challenges, and issues. Furthermore, some of the countermeasures to these threats will be discussed and synthesized. Finally, possible solutions for each type of threats will be introduced before we end with conclusions and future work.
