Sensitivity analysis is a technique used in cybersecurity and risk management to determine how changes in input variables or assumptions impact the outcome of a model or system. By systematically varying parameters, analysts can identify which factors have the most influence on results, helping to prioritize security controls and allocate resources efficiently. Sensitivity analysis is particularly useful in threat modeling, vulnerability assessments, and evaluating the effectiveness of security measures. It enables organizations to understand the robustness of their cybersecurity strategies and to anticipate the potential impact of uncertain or changing conditions. This process supports informed decision-making and enhances overall risk management.
