Abstract: The security of assets within electrical substations is paramount to ensuring the reliable and resilient operation of the energy sector. However, implementing existing industry cybersecurity standards in these environments presents numerous technical challenges. In this work, we provide systematic guidance that emphasizes best practices and prioritizes requirement implementation. We examine the application of Software-Defined Networking (SDN) as a means to enhance security within the IEC 62443 family of standards. Specifically, we offer insights into how the security measures required for compliance with the IEC 62443 security standards can impact the stringent timing constraints of contemporary communication protocols, enabling advanced distribution system operations in the future. Utilizing a testbed modeled after a real-world electrical substation, we demonstrate that while SDN-based security features naturally introduce some additional latency, their operational impact on the network’s strict constraints is minimal.
