Our focus on this podcast is cybersecurity at utilities. Electric, gas, and water utilities face billions of automated probes every year. While only a fraction of probes is successful, the cost of such attacks runs into the billions and systems are vulnerable because of aging infrastructure, a large number of small systems without large IT staffs, and sometimes poor cybersecurity culture.
To discuss the threat situation, we talked with David Ketchen, the assistant general manager at the Littleton Electric Light and Water Departments in Littleton, Mass. , and Bill Murray, a senior vice president with Dominion Energy, an energy holding company in Virginia.
Ketchen detailed a widely reported attack by Chinese hackers at his small utility in 2023 that he and others at the utility became aware of after being contacted by the FBI. Working with the FBI and federal officials from Homeland Security, the utility was able to monitor the hackers and there was no disruption of service. But Ketchen said the utility learned valuable lessons that others, particularly at smaller utilities, can learn from.
Murray offered the perspective of large utilities and the systems their organizations use, defend off attacks from attackers, from transnational criminal organizations and nation states.
