Comparative Study and Improved Security Threats in Cloud Computing

Data security is the fundamental issue of all information systems. In cloud computing environment data security is a serious issue because data is distributed and scattered in various places. Though a lot of work is done in order to provide secure cloud environment, data security is still the main hurdle in the development of this system. This paper reviews various security challenge and techniques to solve security issues in order to achieve data protection in cloud environment. In this paper we have done a comparative analysis of existing research in the field of cloud computing data security and privacy.
