Internet of Things Forensics: A Review

The rapid growth of Internet of Things (IoT) devices brings countless benefits, but it also brings new security and forensics challenges. The IoT system with billions of devices generates a huge amount of evidence which causes big challenges to digital investigators and practitioners who are required to interact with IoT devices to investigate cybercrimes in a forensically sound and timely fashion. These challenges create more opportunities for cybercrimes to attack various IoT application and services resulting in a direct impact on IoT users. As the IoT has incorporated in most aspects of our life, cybercrimes will literally threaten human life, hence, IoT forensics is required to investigate and mitigate against such attacks. Therefore, this paper provides a detailed review of IoT forensics. It started by providing a comprehensive discussion of IoT security involving the need for security by design and security challenges of the IoT system. Then, a review of IoT forensics is presented by highlighting the need for Artificial Intelligence (AI) in IoT forensics, state-of-theart research and recent studies, opportunities and key requirements for a successful IoT forensics. Challenges and suggested solutions of IoT forensics are also discussed. Finally, a discussion of open research directions of IoT forensics is presented. (C) 2020 Elsevier B.V. All rights reserved.
