How Incident Response (IR) Tabletop Exercises Strengthen OT Security Posture
Summary: Dragos Professional Services describes running gamified cybersecurity incident response tabletop exercises (TTXs) for industrial customers, in which facilitators present a simulated intrusion scenario and guide participants through timed "injects" such as personnel being pulled out of play or adversaries tampering with systems. The exercises are entirely simulated and pose zero risk to real industrial systems, and Dragos provides written feedback afterward; the post lists six recommendations, including planning and testing network disconnection, naming positions rather than individuals in IRP documentation, and defining OT-specific severity thresholds that account for physical and life-threatening consequences.
What's compelling: The post notes that IT and OT incident response are not interchangeable because an industrial intrusion can carry physical, process, and life-threatening consequences, and that the first tools a team reaches for, such as ticketing systems or cloud document solutions, may be compromised or cut off by segmentation. It also flags that a single critical individual on a team is a human single point of failure, which facilitators test by pulling that person out as an inject.
