Data collection and audit logs of digital forensics in cloud

Cloud computing has become more important to the users and the service providers, since it is convenient for the users to get the required service from their service providers. As the amount of services given rises, the amount spent on privacy and security of these services too raise. The internet as it is known has been growing insecure in the recent years. With the vast expanse of technology with regard to cloud computing and popularization of the same, the crimes due to these or on these devices will also increase in the near future. The digital environment should be capable of not only preventing the attacks, but it should also be capable enough to deal with the high security threat to defend it. Logs based forensic model approach which is to build a forensic-friendly system has been proposed. A proposed framework for the pursuit of a cloud computing digital investigation is environment that depends on a particular event's “cause and effects”. Search for evidence and to develop hypotheses about such events that at the crime. In the proposed work, Log audit plays a vital role in the forensic framework. Logs model with timestamps can collect the information on the cloud rapidly for forensic resolutions. Hence the complexity involved in these kinds of forensics is reduced.
