“…Randomising IP addresses at a configurable frequency supports evading adversarial discovery. This is meant to thwart the ability of an adversary to conduct reconnaissance and establish communications between devices on the network [51]; MTD has been proven to be effective at increasing the resilience of grid‐wide area networks against certain types of attacks [52].…”

“…In prior work, the communication latencies for various MTD modes were determined for different randomisation time periods; it was found that MTD increased the average latency by less than 1 ms but caused slightly higher dropout rates (∼1 dropout per 33.3 s with IP randomisation every 3 s) [51]. Other approaches to MTD, such as path randomisation, may increase latency more.…”

Increasing penetrations of interoperable distributed energy resources (DER) in the electric power system are expanding the power system attack surface. Maloperation or malicious control of DER equipment can now cause substantial disturbances to grid operations. Fortunately, many options exist to defend and limit adversary impact on these newly-created DER communication networks, which typically traverse the public internet. However, implementing these security features will increase communication latency, thereby adversely impacting real-time DER grid support service effectiveness. In this work, a collection of software tools called SCEPTRE was used to create a co-simulation environment where SunSpec-compliant photovoltaic inverters were deployed as virtual machines and interconnected to simulated communication network equipment. Network segmentation, encryption, and moving target defence security features were deployed on the control network to evaluate their influence on cybersecurity metrics and power system performance. The results indicated that adding these security features did not impact DER-based grid control systems but improved the cybersecurity posture of the network when implemented appropriately.
