Turn-key cybersecurity for TO networks connected to the ONS

Systemic risk: electric sector in the hot seat

A transformer explosion left the state of Amap√° without power in November 2020 and exposed the fragility of the Brazilian electrical system. Could an incident like this be caused by a cyber attack?

Yes. To try to reduce this systemic risk, ANEEL together with the ONS have been working for some years on procedures that shield electrical structures against cyber risks. In 2021, RO-CB.BR.01 was published.

Energy companies need to protect themselves

The new operational routine RO-CB.BR.01 must be implemented by all energy companies that make up the ARCiber, including the agents' operation centers, equipment that participate in the infrastructure for sending or receiving data and voice to operating environments of the ONS or to operating centers of other agents and the operating environment of the ONS.

The minimum controls that make up the procedure must be implemented in two waves, the first in 18 months and the second in 27 months from the date of publication (D0).
