Privacy and security of IoT applications: a review on limitations, and measures to mitigate the security risks of smart grids

Abstract

Nowadays, IoT devices are found everywhere such as schools, universities, malls, and hospitals to perform beneficial functionality. The Internet of things (IoT) is a set of devices that contain electronics, software, sensors, actuators, and connectivity that enable the connection and transmit data. There are many applications of IoT in different fields such as smart home, smart health, smart mobility, and smart grids. Smart Grid is the modern power system, which is a development and integrates the power grids with Information and Communication Technology (ICT) to ensure reliable and safe power delivery to the customers. IoT has developed as one of the technologies that make a smart grid network to be possible. Moreover, there are many security risks and issues that have been raised in the field IoT which can impact the security and privacy of users. Due to this, security became a serious factor we must pay attention to implement the IoT based smart grid networks. Due to the limitations of IoT devices such as computing power, and the powerful of IoT devices, the IoT systems are susceptible to the cyber-attacks that can impact the security and privacy of IoT networks and users. In this paper, we will present the security protocols for IoT, the architecture of IoT, and the cyber-threat in the IoT. As well as, the limitations of IoT devices, security issues and risks that affect the privacy of data exchanged between the Internet of Things (IoT) devices especially in smart grids. Also, the security mechanisms and measures to ensure the security and the user's privacy on the IoT ecosystem and smart grids.
