Electric

Substation automation, distribution SCADA and generation controls from NERC CIP medium-impact assets to the cooperatives below the threshold. The grid is the sector everything else depends on.

The exposure

Below the CIP threshold is still the grid.

Distribution utilities and cooperatives carry the same protocols and the same vendors as the bulk electric system, without the compliance program. Relays and RTUs speaking DNP3 are reachable from more places than anyone has drawn.
