Analysing security risk of a cloud computing system to produce a model for secured business environment

Abstract

These days, almost all the medium and big size of businesses is using the cloud computing system to run their business across the globe and around the clock. It becomes popular and of huge application due to its characteristics such as large scale computation and data storage, virtualization, high expansibility, high reliability and low price service. Cloud Computing is a flexible, cost-effective, and proven delivery platform for providing business or consumer IT services over the Internet. This is an affordable and effective place for businesses to sell and promote their goods and services. However the security problems for the cloud computing system are very significant. It can ruin the rapid development of cloud computing. In Business, cloud Computing presents an added level of risk because essential services are often outsourced to a third party, which makes it harder to maintain data security and privacy, support data and service availability, and demonstrate compliance. The data privacy and service availability in cloud computing are the key security problem. The internet also provides opportunities for fraudulent behaviour and unauthorized access to business and client data. Attacks on the computer system of a business can have immediate and ongoing effects, such as targeting customers for identity crimes or infecting website visitors with malicious software. Due to having combination of various types of models in the cloud computing, the single security method cannot solve its security problem. Various traditional and new technologies and strategies together need to consider for protecting a cloud computing system totally. The aim of this paper is to bring into the deep sight of the cloud computing systems working and then to analyse the cloud computing security problem and its strategy according to the cloud computing concepts and characters. In addition to that, we are identifying the higher vulnerabilities in this type of systems and the most important threats found in the literature study related to Cloud Computing and its environment as well as to identify and relate vulnerabilities and threats with the possible solutions.
