Internet of Energy (IoE) is one of the important concepts for facilitating technological, economic, and social development, helping people in their lives. The IoE paradigm encompasses solutions from generation units to loads, and one of its principal concerns is digitalized substations. The evolution of electrical energy systems through digitalized substations is mainly based on IEC 61850, allowing more efficient monitoring, control, automation, and protection systems. Despite the numerous benefits, this digitization brought cybersecurity challenges, mainly associated with the IEC 61850 GOOSE protocol. One of the most critical aspects of securing communication systems in digitalized substations is which mitigation method is more efficient for this specific and crucial scenario. Equally important, the security requirements, vulnerabilities, and solutions lack correlation. However, very few articles focus on this theme …
