Today’s LiveWire Spotlight examines the latest Standards Authorization Request (SAR) for Project 2021-03, which addresses the proper security approach where two geographically distant BES Cyber Systems (BCS) exchange data across a serial communications link. It focuses on a scenario where an IP/serial protocol converter exists at a high-impact Control Center on one end of the data path, but is not needed at the remote site.
The initial draft of the latest Standards Authorization Request for Project 2021-03: CIP-002 Communications Protocol Converters and its unofficial comments form have been posted for a 30-day review. Your feedback is due back to the project team by March 31, 2023.
