Digital Forensic Investigation Framework for Internet of Things (IoT): A Comprehensive Approach

Internet of Things (IoT) is receiving more and more attention in recent years. Even though a great number of researches have been going on focusing the field IoT, research on Digital Forensics Investigation (DFI) techniques are still little focused. Till now IoT platforms have not fully matured to adapt with the existing Digital Forensic(DF) tools, methods, and procedures. The prime reason is the nature of the cloud, network and IoT infrastructures (e.g. heterogeneity, distributed, jurisdiction, data duplication, multi-tenancy etc.). As a result, it is a very challenging task of locating, identifying, examining, analyzing, and presenting the potential IoT-based forensic evidence for digital forensic from the device, Network and, cloud environment. Consequently, there is no fully adapted international standard for an ideal framework to conduct DFIs. Because of this, we are proposing a comprehensive DFI process framework for the IoT environment that is able to enable more efficient and effective for DFI. The aim of this paper is to present a more comprehensible DFI framework for digital forensic professionals and experts. Also, it would be a proper guideline to guide the investigators and would also be useful in training of the fledgling i nvestigators. M oreover, i t r educes the dependence on the Cloud Service Provider (CSP) at the time investigation is going on.
