Internet of Things Digital Forensic Investigation Using Open Source Gears

To conduct an accurate digital investigation, it is necessary that the investigator can analyze very complicated events within a particular case. IoT stores subtle human-related information that is considered a perfect source for collecting such evidence. In recent years, there has been a lot of open source and commercial tools available for digital forensics investigation. This research work aims to explore a way of conducting digital forensics investigations with cost-effective open source tools suitable for acquiring and examining evidence from IoT. In addition to the compiled list of open source tools recommended, a three-layer IoT forensic investigation framework, consisting of the IoT Application Server Layer, Communication or Network Layer and IoT Device Layer is proposed. The involvement of all three layers of the proposed framework along with the utilization of recommended tools are highly encouraged for conducting a complete investigation of IoT Forensics.
