The Internet of Things (IoT) Forensic Investigation Process

Abstract

The Internet of Things (IoT), a rapidly evolving network of connected devices, is expected to grow to an astounding 41.6 billion units by 2025. This exponential growth, while beneficial in terms of data collection and exchange, has also increased the vulnerability of these devices to sophisticated cyberattacks, notably the Mirai botnet malware. This paper centers on the distinctive challenges posed in the field of IoT forensics. These challenges are primarily due to the intricate and diverse nature of IoT devices and ecosystems, which complicate the application of standard forensic tools and methodologies. One of the most significant hurdles in IoT forensics is data acquisition, considering the vast diversity of devices and the lack of specialized forensic tools tailored to these unique environments. The paper conducts a thorough literature review to explore these challenges in depth, aiming to not only provide a comprehensive understanding of the current state of IoT forensics but also to identify potential avenues for future research and development. It also highlights key strategies and solutions to enhance the security of IoT devices and to support forensic investigators in navigating the complexities of IoT ecosystems. Through this exploration, the paper contributes valuable insights and guidelines, poised to shape the advancement of IoT device security and forensic investigation techniques.
