Abstract
The Internet of Things (IoT) involves the rapid adoption of smart, adaptive and connected devices and is rapidly being deployed in critical infrastructure areas like heath, utility, homes, transportation and industries. It brings benefits and reliability to consumers, the haste and its large scale connection however poses serious risks to consumers. These risks include new attack vectors, new vulnerabilities and physical destruction through remote access. The IoT brings implications on cyber security as these devices are connected through the internet. Investigating digital crimes in the IoT domain using digital forensic technology is more challenging. Evidence extraction for forensic investigation is difficult since equipment could lose their data if left to operate for a long time; there is also the problem of jurisdictions. In this paper, we review literature related to forensics in the IoT and analyse the various models that have been proposed. The survey revealed the difficulty in digital evidence extraction in the IoT domain.
