  Internet of Things (IoT) is the utmost assuring framework to facilitate human
life with quality and comfort. IoT has contributed significantly to numerous
application areas. The stormy expansion of smart devices and their credence for
data transfer using wireless mechanics boosts their susceptibility to
cyber-attacks. Consequently, the rate of cybercrime is increasing day by day.
Hence, the study of IoT security threats and possible corrective measures can
benefit the researchers to identify appropriate solutions to deal with various
challenges in cybercrime investigation. IoT forensics plays a vital role in
cybercrime investigations. This review paper presents an overview of the IoT
framework consisting of IoT architecture, protocols, and technologies. Various
security issues at each layer and corrective measures are also discussed in
detail. This paper also presents the role of IoT forensics in cybercrime
investigation in various domains like smart homes, smart cities, automated
vehicles, healthcare, etc. Along with the role of advanced technologies like
Artificial Intelligence, Machine Learning, Cloud computing, Edge computing, Fog
computing, and Blockchain technology in cybercrime investigation are also
discussed. At last, various open research challenges in IoT to assist
cybercrime investigation are explained, which provide a new direction for
further research.
