What does R2.1 specifically require to evaluate the response plan effectively?

R2.1 specifically requires the testing of plans with actual reportable incidents to evaluate the response plan effectively. This requirement emphasizes the importance of real-world application and assessment of emergency response procedures. By using actual incidents, organizations can critically analyze their response capabilities and identify any gaps in their processes or execution. This hands-on approach allows for a more thorough evaluation than hypothetical scenarios, ensuring that the response plan is not only theoretically sound but also practical and effective in real situations.

The focus on actual reportable incidents allows the organization to assess the adequacy of their response in tangible circumstances, facilitating continuous improvement in their critical infrastructure protection strategies.
