Case Study of Cloud Computing Security Issues and confidentiality Challenges

Cloud computing is a term, which involves virtualization, distributed computing, networking, software and web services. A cloud consists of several elements such as clients, data center and distributed servers. It includes fault tolerance, high availability, scalability, flexibility, reduced overhead for users, reduced cost of ownership, on demand services etc.Cloud Computing offers better computing through improved utilization and reduced administration and infrastructure costs. Cloud Computing is the sum of Software as a Service (SaaS) and Utility Computing. Cloud Computing is still at its infant stage and a very new technology. Therefore, most of the users are not very confident to adopt it.The main issue that faced the cloud computing is “security”. In this paper, we try to find out what countermeasures best strengthen the confidentiality, integrity and availability (CIA) of the implementation of cloud computing within the DOD This will be done by analyzing threats and countermeasures within the context of the ten domains comprising the Certified Information System Security Professional (CISSP) Common Body of Knowledge (CBK). The ten domains include access control; telecommunications and network security; information security governance and risk management; application security; cryptography; security architecture and design; operations security; business continuity planning and disaster planning; legal regulations, compliance, and investigation; and physical security. The results will provide a comprehensive guide for any Department of DefenseDoD entity attempting to secure its cloud solution.
