Industry 4.0 is that the digital transfiguration of production and connected industries with worth creation processes called smart factory. The building blocks of Industry 4.0 are fusion of Cyber Physical systems, Artificial Intelligence, Robotics, cloud computing and the Internet of things(IoT). In Industry 4.0, the Supervisory Control and Data Acquisition (SCADA) systems performs more intelligence, automation and self-learning with the centralized technologies. With these, the SCADA controls manufacturing processes in industries by monitoring, gathering and processing of real time data. At the time of making a product through Industry 4.0 in any factory, if any faults occurred in the Supervisory systems, the entire system gets collapsed and leads to harmful to consumers. The advanced digital forensics techniques for the entire Industry 4.0 architecture are needed to identify the errors in the real time processes and new tools to be designed to ratify during live processes. In this work, some of the forensics challenges in the SCADA systems of Industry 4.0 and the available digital forensics tools for live systems are discussed with possible proposed solutions. It also discusses the limitations and difficulties faced in digital forensics of Industrial Control Systems.
