Chairman’s Message

January 2022

“It was the best of times, it was the worst of times, it was the age of wisdom, it was the age of foolishness, it was the epoch of belief, it was the epoch of incredulity, it was the season of light, it was the season of darkness, it was the spring of hope, it was the winter of despair.”

You would think Charles Dickens was writing about this past year. 2020 and COVID was quite a challenge, but it didn’t stop there. Ransomware was widespread and hit close to home. The Colonial Pipeline incident created a seismic shift for critical infrastructure and our industry in particular. Government attention was sharply focused on oil & gas, especially after 90% of the gas stations in the D.C. area ran out of gas. TSA issued Security Directives for the pipeline industry. Several oil & gas companies were newly included under Section 9 of Executive Order 13636 – the most critical of critical infrastructure “where a cybersecurity incident could reasonably result in catastrophic regional or national effects on public health or safety, economic security, or national security.” In addition to the criminal threat, geopolitical concerns have driven heightened cybersecurity awareness for critical infrastructure, with tensions around Ukraine rising higher each day (and hopefully not boiling over by the time you read this).

With escalating tensions and increased attention on oil & gas cyber defense, I am glad we have the ONG-ISAC team that we can reach out to with questions and concerns. I appreciate not “going it alone”, even if only to know that I am not the only one out there dealing with these cybersecurity issues.

Thank you to all our members for the information you have shared and the contributions you have made. Thank you to our ONG-ISAC staff, especially our SOC analysts, Hassan and Jacob, for all their hard work. Thank you, Angela, for leading the ONG-ISAC charge and driving information sharing. Finally, thank you to all of the Board members, current and past, who put us on the threat information sharing track and made sure we didn’t go off the rails.

Keep Calm and Share On.

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.
