Cyber Forensic Model for Data Security in Cloud Computing

Cloud Computing is considered to be the next generation of information technology framework. It is the next generation computing platforms that can provide dynamic resource pools, virtualization and high availability and online storage systems. The new character brings a lot of new security challenges which have not been taken into account completely in the current cloud computing system. There are number of security issues related to online storage of data on the cloud. Evidence of integrity preservation of data is a crucial aspect to be considered. In this paper, we propose a model to provide evidence of integrity preservation of the data uploaded to the online cloud storage and downloaded from the cloud storage systems. Moreover, accessibility of logs is a burning issue these days. This challenge is overcome by providing a customised user and resource log including crucial information like by whom was the object accessed, when it was accessed, which operations were performed on which objects, and the status of operations requested. This can boost up the trust of the users leading to increased adoption of cloud computing services in areas like business, healthcare and education, thus directing towards lower cost and long term benefits to the society.
