The OEB has issued a letter describing an initiative to implement a requirement for utilities to periodically submit an independent cyber-security assessment based on the Ontario Cyber Security Framework (OCSF). The proposal would require utilities to have a qualified third-party assess their maturity against the OCSF and then report this to the OEB. OEB staff looks forward to the opportunity to present this initiative and engage with industry participants at an upcoming CSAC meeting. All licensed electricity transmitters and distributors are encouraged to participate.
