Finally, the proposed hybrid cybersecurity solution is implemented with the developed testbed and its effectiveness is demonstrated. Utilizing the developed testbed FDI attacks in the form of replay and masquerade attacks on are launched and the impact of attacks on electrical side is studied. Furthermore, a novel hybrid cybersecurity solution by the name of sequence content resolver is proposed to counter such attacks on the GOOSE protocol in smart grids. This paper presents a testbed and methodology to simulate FDI attacks on IEC 61850 standard compliant Generic Object-Oriented Substation Events (GOOSE) protocol using real time digital simulator (RTDS) together with open-source tools such as Snort and Wireshark. Hence, there is a need to develop a cybersecurity testbed and novel mitigation strategies to study the impact of attacks and mitigate them. Attackers exploit the standardized semantics of the communication protocols to launch different types of attacks such as false data injection (FDI) attacks. Standardized communication in smart grids has an unwanted consequence of higher vulnerability to cyber-attacks. It delivers IoT solutions across Connected Products, Edge Control, Apps, Analytics, and Services, along with cybersecurity solutions.IEC 61850 is emerging as a popular communication standard for smart grids. Schneider Electric's cybersecurity solutions are backed by EcoStruxure Grid, an interoperable, open, and IoT-enabled platform, helping you make most of your data and integrate new and connected technologies in the energy sector. As an IoT-based smart grid consists of millions of nodes, it has a large attack surface for an IoT-related cyberattack, which might have devastating effects on the reliability of the smart grid system. Smart grid systems’ characteristics such as delay constraints, heterogeneity, scalability, bandwidth, and others make it quite challenging to deploy comprehensive and uniform security approaches across all network segments. What are the cybersecurity challenges and solutions in the smart grid? Therefore, it is important for utilities to adopt smart grid cybersecurity solutions for data management and privacy concerns, layered security approaches, strategic issues, vulnerable areas, threat profiling, and maintaining electric grid cybersecurity.Ĥ. However, the increased use of IT-based electric power systems increases cybersecurity vulnerabilities, leading to the increased need to adopt resilient cybersecurity solutions. Smart grid systems help utilities in conserving energy, reducing costs, increasing transparency and reliability, and making processes highly efficient. What is the importance of smart grid cybersecurity? Therefore, it is imperative to maintain the electric grids' cybersecurity.ģ. Cybersecurity is a major concern in such critical systems because the confidentiality, availability, or integrity of communication systems is broken down due to cyberattacks, it can disrupt public order and national security and cause large-scale economic damage or loss of life. It is important to understand that IoT-based smart grid systems have critical infrastructure and include complex devices as well as architecture. Why cybersecurity is a concern in smart grids? It is important to protect smart grids against potential terrorist threats, espionage threats, and vulnerabilities caused by natural disasters, equipment failures, and user errors.Ģ. Rather, it should be considered a part of smart grid development. Furthermore, cybersecurity should not be interpreted as a retrofit. Therefore, it is important to secure smart grid physical systems against cyberattacks and maintain cybersecurity for power grids. However, while these smart grids offer a wide array of benefits, they are highly vulnerable to cyberattacks. With the innovations and advancements across the globe, traditional grids are being transformed into smart grids. What are the basics of smart grid cybersecurity?
