Survey of IoT Security: Application Areas, Threats and Solutions

The current communication era is commonly called the Internet of Things (IoT). The IoT facilitates data generation, reception, and transmission among tangible entities. A multitude of IoT applications prioritize the automation of diverse processes to endow non-living entities with autonomous functionality. Thanks to current and future IoT applications, user comfort, effectiveness, and level of automation will probably increase. However, such a world needs high-security, private, authentic, and attack-recovery mechanisms. Implementing the necessary changes to the building blocks of IoT applications is essential to achieving secure end-to-end IoT environments. This chapter will comprehensively examine the obstacles related to security and the conceivable hazards presented by applications of the IoT. Following a discussion of the potential risks associated with the IoT, a look will be taken at the many different technologies currently in use and those still in the development stage. The enhancement of IoT security is the focus of current research into four distinct technologies: Edge computing, Fog computing, Blockchain, fog computing, Edge computing, and machine learning.
