Cloud is an environment of the hardware and software resources in the data centers that provide diverse services over the network or the Internet to satisfy user s requirements. Amid Cloud s several advantageous features, lots of users don t have desire to upload their sensitive or confidential data in the cloud computing environment. Cloud service porviders try to gain users trust by implementing various methods like Firewalls and Virtualization, but these mechanisms would not provide the complete data protection because of its vulnerabilities over the network. In this paper, we have discussed five major security problems in cloud computing based on Hexatier survey and have offered different data protection tools and techniques in order to improve the overall security and privacy in cloud computing. In addition, we have compared characteristics of these various methods in a table.
