Chairman’s Message

January 2021

Boy, what a year 2020 was. None of us could have seen what was coming last year. Despite all of the challenges we have all been dealing with, I am very pleased with the information sharing and collaboration that has taken place through the ONG-ISAC. It is very encouraging to see the timely analyst-to-analyst sharing through our real-time, encrypted communications platform Vaporstream. With the recent disclosure of the SolarWinds breach and associated cyber intrusion activity, we have seen a rapid-fire sharing of cyber threat intelligence by the ONG-ISAC, with our members sharing not just information about the attack, but their responses to the attack as well. It is amazing how the “shared brain” of our membership can process information from disparate sources and boil it down to the key pieces of information. Our industry was strengthened when members with deeper cyber threat analysis capability have provided other members insight and guidance on analyzing the situation and how to best discern the level of risk faced by the compromised software. This situation perfectly demonstrated the role and capability of the ONG-ISAC to facilitate sharing of threat information and collaboration in response to threats to our industry and membership. I would like to thank all of our members for the threat information they have shared and the contributions they have made.

Meet the Board of Directors

The board of directors and the officers are responsible for the stewardship of the corporation and are elected to ensure the ONG-ISAC has the critical capabilities needed to achieve its objectives.
