A Systematic Review of IoT Forensics-Based on a Permissioned Blockchain

The emerging benefits of the Internet of Things (IoT) devices have been observed within the industries. This development has introduced several issues, including increased vulnerability to potential cyberattacks and digital forensics. Forensic investigations associated with IoT need to be examined in a forensically sound manner using a standard framework. However, adopting the current traditional digital forensics tools introduces various challenges, such as identifying all IoT devices and users at the crime scene. A forensic analysis must preserve the “chain of custody” by maintaining a complete record of the evidence from the point of seizure or interception until it is tendered in court. This paper examines the suitability of a blockchain-based solution for IoT forensics for implementing tamper-resistant data storage, ensuring data integrity and immutability. Therefore, in this paper, we aim to propose a permissioned blockchain integration solution for the IoT forensics (PBCIS-IoTF) framework. Our proposed framework will focus on reviewing permissioned blockchains (Hyperledger Fabric) to enhance the IoT forensics challenges while aiming to address whether the PBCIS-IoTF could be utilised to better enhance the IoT data integrity and authenticity.
