Abstract

The Internet of Things (IoT) encompasses the collective network of electrical devices and the technology that enables them to send and receive data. The use of IoT technologies in industrial settings, such as transportation, manufacturing, and energy is referred to as the Industrial Internet of Things (IIoT). With the expansion of IoT in homes and IIoT in the energy sector has come an increase in the number of devices connected with each other. Engineers have utilized this network to develop sophisticated smart systems that combine sensing, processing, actuation, and control to produce smart environments. Along with the benefits of IoT and IIoT expansion in smart systems come cybersecurity risks from possible exploitation of vulnerabilities. Since IIoT devices are connected with each other, a cyberattack on a smart system can lead to a large attack surface with devastating effects.

This thesis will serve to identify IoT and IIoT cybersecurity threats in smart devices and their impact on the grid. IoT device security will be analyzed in smart homes, and IIoT device security will be analyzed in substations and utility control centers. Common communication protocols used in IoT and IIoT devices will be compared to determine their level of vulnerability to cyberattacks. Furthermore, this thesis will discuss attack scenarios and explain the idea of a cascading effect of vulnerabilities in devices. To visualize and simulate attack scenarios, a model power system will be created on RT Lab and EXata CPS. From here, the results collected will be presented. The findings will discuss potential vulnerabilities and provide solutions for enhancements in IoT and IIoT security for smart power systems.
