The Internet of Things (IoT) has introduced connection in most appliances and different industrial objects. Although it is evident that such interconnection provides high levels of convenience and efficiency, the problem of digital forensics is apparent here. Over the past few years, studying the IoT device-involved mishaps necessitates the application of unique methods to ensure the safety and efficiency of approaches used in evidence collection and analysis. This chapter aims at discussing various strategies of performing IoT forensics so as to deal with the difficulties that characterize such devices. They will start by looking at the type of environment that IoT operates in, the different devices that are in use, the different communication channels and data interfaces. It is imperative that forensic professionals comprehend these nuances as part of their endeavors to penetrate the manifold arrangements of IoT networks. The primary problem to address in IoT forensics is therefore the large and heterogeneous amount of data from connected objects. This type of saturation can prove problematic when using traditional methodologies of forensic analysis, meaning that new methods and means of both data acquisition and analysis must be developed. This chapter outlines the processes of investigating IoT devices for digital evidence, how to acquire and preserve it while still observing chain of custody and integrity. Additionally, IoT devices cannot be relied on as having installed standard security features, hence opening themselves to exploitation. This puts into question not only for device owners but also for forensic practitioners when confronted with infected systems or media. This chapter presents how to evaluate IoT devices’ security status and how to identify that a device has been tampered with or accessed illicitly IoT forensic purposes. Further, the question of bureaucratic law and ethics also remains a focal point of concern especially understanding rights of privacy and protection of data for IoT forensics purposes. Offenders have to operate within these numerous legal systems sometimes concurrently with ensuring that the methods used by the investigators do not violate the forensic norms. Last but not the least, final section of this chapter paves way to look into the future trends of IoT forensics, the prime areas that are already in their nascent stage such as the advent of new and enhanced forensic tools and technique, influence of artificial intelligence and machine learning in forensics, and changing dynamics of threats. Consequently, this chapter will offer a brief on the established IoT forensics best practices as an effort to empower the forensic investigators, law enforcement agencies, and cybersecurity professionals to better handle the myriads of difficulties that stem from the constantly increasing IoT devices populace.
