Detailed Information for the Best Practice: 9-8-8025

Number 9-8-8025
Priority Critical
Description Protection from SCADA Networks: Telecom/Datacomm OAM&P networks for Service Providers and Network Operators should be isolated from other OAM&P networks, e.g., SCADA networks, such as for power, water, industrial plants, pipelines, etc.
·         Isolate the SCADA network from the OAM&P network (segmentation)
·         Put a highly restrictive device, such as a firewall, as a front-end interface on the SCADA network for management access.
·         Use an encrypted or a trusted path for the OAM&P network to communicate with the SCADA "front-end."
Network Type(s) Internet/Data
Industry Role(s) Service Provider; Network Operator

Reference/Comments Note: Service providers MAY provide an offer of 'managed' SCADA services or connectivity to other utilities. This should be separate from the provider's OAM&P network. ITU-T Rec. X.1051.
