With the increasing popularity of cloud services and their potential to either be the target or the tool in a cybercrime activity, organizational cloud services users need to ensure that they are able to collect evidential data should they be involved in litigation or a criminal investigation. In this paper, we seek to contribute to a better understanding of the technical issues and processes regarding collection of evidential data in the cloud computing environment. Using VMware vCloud as a case study in this paper, we describe the various artefacts available in the cloud environment and identify several forensic preservation considerations for forensics practitioners. We then propose a six-step process for the remote programmatic collection of evidential data to ensure as few changes as possible are made as part of evidence collection and that no potential evidence is missed. The six-step process is implemented in a proof of concept application to demonstrate utility of the process.
