Abstract	Digital forensics can be defined broadly as the process of identifying, collecting, examining, and analyzing digital evidences, then reporting the results. The evidences are expected to be presented in the court, and therefore should be kept authentic during the entire investigation. Thus, the evidence collection process is of great importance. In traditional forensics, digital evidences are collected from computers, servers, firewalls, etc. In IoT environments, they should be also collected from sensors, tags, home appliances, wearable smart devices, etc. However, these devices are very diverse, produced by different vendors, using various data formats. Moreover, they are scattered over wide areas, e.g., smart cities, smart farming. They are connected through wired and wireless networks, and thus the network boundaries become unseizable, which makes digital evidence collection very challenging. In this chapter, we focus on the process of digital evidence collection in IoT, which is a key in any criminal investigation. We study and categorize the different IoT device types and their features. Then, we present the different data formats integrated into IoT devices and how their data can be collected, in compliance with the forensic investigation protocol. Lastly, we present existing IoT forensic tools and their features and limitations. © 2023 by World Scientific Publishing Co. Pte. Ltd.
