The Internet of Things (IoT)is the network of physical objects accessed through the Internet that can identify themselves to other devices and use embedded technology to interact with internal states or external conditions. The continued growth of the internet of things phenomenon has led to influx of a number of cybersecurity risks. This paper aimed at analyzing the most common classes of cybersecurity threats associated with IoTs and their impact to the security of the information systems. To achieve this, we examined and reviewed cybersecurity risks related literature of the IoT leading to the specification of the Internet of Things cybersecurity landscape. Finally, this review provides insights for cybersecurity risks evolution, suggesting tools, methods and potential approaches that can help ensure a safe IoT environment.
