What have you done to prepare for a cybersecurity event?
My personal observation is that most emergency managers are focused on many other aspects of disaster readiness and cybersecurity is secondary or even a tertiary concern. Perhaps, it is not on the back burn, and it isn't even on the counter top!
Maybe this Emergency Management Institute opportunity might be helpful, check out Virtual Tabletop Exercise Series (VTTX) — Cyber Security Focus.
Eventually, cyber will come and bite you and your broader community!
