Fog Forensics: A Comprehensive Review of Forensic Models for Fog Computing Environment

Numerous potential social advantages are offered by fog computing, including personalized healthcare, smart cities, agri technology, automated transportation, consumer IoT, and many more. Ambient computing at previously unfathomable scales is made possible by the extremely dynamic and complex nature of fog computing and its low latency communication networks connecting sensors, devices, and actuators. The need to look for digital forensic methods that may effectively be used to solve computer-related crimes utilizing IoT devices is being driven by the rise in IoT devices. Fog computing adds greater threats to privacy and security as it is becoming challenging given the increasing number of linked devices. The existing forensics models are not sufficient to handle data from the fog cloud. In this paper, we present a thorough review of the existing state-of-the-art forensic models that can be applied to fog cloud environment and this work can further be used to promote extensive research and development of fog forensic models.
