game-theoretic model

A game-theoretic model is a mathematical framework used to analyze strategic interactions among rational decision-makers. It is not a specific control but a powerful analytical tool within a risk management system. While no standard mandates its use, its application aligns with the systematic risk assessment principles of ISO 31000:2018. In cybersecurity, it helps model attacker-defender scenarios, supporting the threat analysis processes described in ISO/IEC 27005. Unlike statistical models that rely on historical data, game theory excels at analyzing situations involving intelligent adversaries and complex causality, such as trade secret theft or cyber-attacks, by focusing on players, strategies, and payoffs.

Applying a game-theoretic model involves a structured process. For trade secret protection, the steps are: 1) **Scenario Definition**: Identify players (e.g., company, competitor), define their strategies (e.g., invest in protection, litigate), and quantify payoffs (e.g., market share, legal costs). 2) **Model Construction & Solving**: Build a payoff matrix or game tree and solve for equilibria, such as the Nash Equilibrium, to predict likely outcomes. 3) **Strategy Formulation**: Use the equilibrium analysis to inform decisions. For example, a model might show that if a company's security investment is below a certain threshold, a competitor's best strategy is to attempt infringement. This insight can justify increasing the security budget, potentially reducing infringement risk by over 15%.

Taiwan enterprises face three main challenges: 1) **Data and Parameterization**: Difficulty in quantifying intangible payoffs and competitor intentions. Solution: Use expert judgment and sensitivity analysis to work with a range of values instead of single points. 2) **Talent Scarcity**: A lack of professionals with combined expertise in game theory, industry knowledge, and law. Solution: Form cross-functional internal teams and collaborate with external experts like Winners Consulting for knowledge transfer. 3) **Management Buy-in**: The model's complexity can be a barrier to acceptance by senior leadership. Solution: Use visualizations and pilot projects on high-impact issues to demonstrate value and communicate insights effectively, focusing on strategic outcomes rather than mathematical details.
