A survey on IoT security: application areas, security threats, and solution architectures

The speed of connecting physical machines to the internet is significantly increasing day by day. As per the recent report by Gartner, around 8.4 billion connected objects are available in the world It is predicted that the number of things is expected to increase to 20.4 billion by the end of 2022. The utilisation of IoT applications is increasing day by day to make people's life easier. According to Altulaihan et al. Internet of things (IoT) mainly differs from the internet, which depends on human input to execute. As opined by IoT devices are unique in terms of security vulnerabilities, due to the heterogeneity and complexity of technology. However, addressing the security of IoT devices is more critical. Machine learning methods such as cost-sensitive classification techniques are used in every research to measure the performance of the systems.
