Summary

The Hague Centre of Strategic Studies and Leiden University propose a novel Multi-Agent Influence Diagram (MAID) framework to model and assess the effectiveness of counter-hybrid threat measures against hostile actions below the conventional military threshold. This approach unifies previously bifurcated game-theoretic and probabilistic modeling methods to clarify the impact of countermeasures on adversarial behavior. The model balances countermeasure costs, their ability to dissuade adversaries, and their potential to mitigate hybrid threat impacts. Researchers simulated 1000 semi-synthetic variants of a real-world-inspired cyberattack scenario on critical infrastructure, involving attacking agent A and defending agent B, to evaluate five counter-hybrid measures. These measures ranged from strengthening resilience and denial to dissuasion through punishment. The analysis primarily evaluates overarching characteristics of these measures, allowing for generalization of effectiveness and examination of parameter sensitivity, with market restrictions often proving most optimal despite high costs.

Key takeaway

For research scientists developing national security strategies, this MAID framework offers a robust prototype for systematically evaluating and prioritizing counter-hybrid policies. You should consider integrating both probabilistic and game-theoretic approaches to account for deep uncertainties and strategic adversarial responses. This model can help you design more effective cross-domain deterrence measures by balancing costs, dissuasion capabilities, and damage mitigation, especially when facing sophisticated cyber threats on critical infrastructure.

Key insights

A novel MAID framework unifies game theory and probabilistic modeling to assess counter-hybrid threat effectiveness under deep uncertainty.

Principles

• Deterrence by denial and punishment are key.
• Perception is crucial for successful deterrence.
• Cross-domain strategies are essential for hybrid threats.

Method

The method integrates Bayesian networks and game theory within a multi-agent influence diagram, using expert-elicited probability distributions for costs, deterrence, and mitigation to simulate strategic interactions and derive subgame perfect equilibria.

In practice

• Prioritize market restrictions for versatile defense.
• Invest in intelligence sharing for cost-effective mitigation.
• Develop meticulous communication strategies for deterrence.
