Industrial IoT: Challenges and Mitigation Policies

In today’s world, with the innovations of various technologies and the subsequent growth and competition in various sectors, technologies such as IoT are playing a key role in amalgamating technology and industries. This vision to use IoT in the industry is to complement the needs of industries, increase automation, receive feedback, timely response, and most importantly increase production by many folds. This drastic change and implementation of technology helped to generate more revenue but the threat of cyberattacks is still prevalent and is largely overlooked. Industrial IoT which does not follow any standardized security protocols is heavily vulnerable to cyberthreats and critical sectors like power plants, smart meters, etc., which uses IoT to connect are at high risk. In this paper, a basic overview of the cybersecurity issues in industrial IoT and various cyberattacks related to different tiers of IoT architecture is reviewed. Also, research work has discussed various mechanisms that can be used to thwart and mitigate cyberattacks on the industrial IoT systems.
