Disposable Virtual Machines and Challenges to Digital Forensics Investigation

Digital forensics field faces new challenges with emerging technologies. Virtualization is one of the significant challenges in the field of digital forensics. Virtual Machines (VM) have many advantages either it be an optimum utilization of hardware resources or cost saving for organizations. Traditional forensics’ tools are not competent enough to analyze the virtual machines as they only support for physical machines, to overcome this challenge Virtual Machine Introspection technologies were developed to perform forensic investigation of virtual machines. Until now, we were dealing with persistent virtual machines; these are created once and used many times. We have extreme version of virtual machine and that is disposable virtual machine. However, the disposable virtual machine once created and are used one time, it vanish from the system without leaving behind any significant traces or artifacts for digital investigator. The purpose of this paper is to discuss various disposable virtualization technologies available and challenges posed by them on the digital forensics investigation process and provided some future directions to overcome these challenges.
