Digitisation trends of infrastructure networks may provide benefits for maintenance and operations, but they also introduce risk for opportunists and sophisticated cyber criminals to attack power systems.
In the past, power systems protection and control technology was developed with little concern for cybersecurity, . Traditional SCADA control telecommunications infrastructure was isolated from the general public, and security scrutiny remained entirely on preventing internal threats.
Today, new control and automation equipment is leveraging our global learnings of the internet, transitioning to using the Internet Protocol (IP) stack as the primary means of communications. There are many advantages in doing this, provided that vendors adopt the same IT network management standards that are currently used in securing traditional business computing assets.
Cybersecurity is a specialist discipline in IT, but in this article our aim is to build understanding of these concepts for electrical engineers. We review the current state of cybersecurity implementation in electricity distribution networks: the core threats and relevant engineering standards. The goal is to provide electrical engineering practitioners and managers with a roadmap to raise the bar for would-be assailants, and to maintain the reliability of electricity for our communities we serve.
