Protecting IIoT devices at the grid edge is arguably one of the more difficult tasks in cybersecurity. There is a wide variety of devices, many of which are deployed and operate in a highly specific manner.
In the energy sector, DERs such as solar photovoltaics introduce information exchanges between a utility’s distribution control system and the DERs to manage the flow of energy in the distribution grid. These information exchanges often use IIoT technologies that may lack communications security. Additionally, the operating characteristics of DERs are dynamic and significantly different from those of typical power generation capabilities. Timely management of DER capabilities often requires a higher degree of automation. Managing the automation, the increased need for information exchanges, and the cybersecurity associated with these presents significant challenges.
The NCCoE is building an example solution focused on helping energy companies secure IIoT information exchanges of DERs in their operating environment that demonstrates the following capabilities:
authentication and access control to ensure that only known, authorized systems can exchange information
communications and data integrity to ensure that information is not modified in transit
malware detection to monitor information exchanges and processing to identify potential malware infections
command register that maintains an independent, immutable record of information exchanges between distribution and DER operators
behavioral monitoring to detect deviations from operational norms
analysis and visualization processes to monitor data, identify anomalies, and alert operators
Protecting IIoT devices at the grid edge is arguably one of the more difficult tasks in cybersecurity.
Organizations participating in this project submitted their capabilities in response to an open call in the Federal Register for all sources of relevant security capabilities from academia and industry (vendors and integrators). The following respondents with relevant capabilities or product components (identified as “Technology Partners/Collaborators” herein) signed a Cooperative Research and Development Agreement to collaborate with NIST in a consortium to build this example solution.
The NCCoE and our project collaborators presented a brief overview of the example solution detailed in NIST SP 1800-32 to the Sandia National Laboratory/SunSpec Alliance Distributed Energy Resources Working Group, followed by a question and answer session in the video.
