Digital evidence in fog computing systems

Fog Computing provides a myriad of potential societal benefits: personalised healthcare, smart cities, automated vehicles, Industry 4.0, to name just few. The highly dynamic and complex nature with its low latency communication networks connecting sensors, devices actuators facilitates ambient computing at scales previously unimaginable. combination Machine Learning, Data Mining, the Internet Things, supports endless innovation in our data driven society. incurs new threats security privacy since these become more difficult when there are an increased number connected devices, such (for example sensors) typically have limited capacity for in-built security. For law enforcement agencies, existing models digital forensic investigations ill suited emerging fog paradigm. In this paper we examine procedural, technical, legal, geopolitical challenges associated Computing. We highlight areas that require further development, posit framework stimulate consideration discussion around extracting evidence from systems.
