How can simulation exercises assess IACS cybersecurity readiness?

Simulation exercises are a vital method for assessing the cybersecurity readiness of Industrial Automation and Control Systems (IACS). The approach of testing incident response capabilities in realistic scenarios allows organizations to actively engage in situations that closely mimic potential cyber threats. This hands-on experience enables teams to identify not only their strengths—such as effective communication and decision-making under pressure—but also areas that require improvement.

Through these realistic scenarios, participants can practice their roles, understand procedural workflows, and evaluate the functionality of their security measures, all of which contribute to a well-rounded preparedness strategy. The dynamic nature of simulation exercises reveals how teams react in real-time, which is critical in providing insights that static evaluations, such as reviewing documentations or past reports, cannot fully capture. This experiential learning approach ensures that when actual incidents occur, the organization is better equipped to respond effectively and efficiently, thereby enhancing overall cybersecurity posture.
