TL;DR

This chapter examines RedCyber, a synthetic cyber conflict, demonstrating how game-theoretic methods capture the interdependencies of cyber operations and directions for future research on resilience, cros-echelon planning, and the evolving role of AI in cyber warfare.

Abstract

Cyber warfare has become a central element of modern conflict, especially within multi-domain operations. As both a distinct and critical domain, cyber warfare requires integrating defensive and offensive technologies into coherent strategies. While prior research has emphasized isolated tactics or fragmented technologies, a holistic understanding is essential for effective resource deployment and risk mitigation. Game theory offers a unifying framework for this purpose. It not only models attacker-defender interactions but also provides quantitative tools for equilibrium analysis, risk assessment, and strategic reasoning. Integrated with modern AI techniques, game-theoretic models enable the design and optimization of strategies across multiple levels of cyber warfare, from policy and strategy to operations, tactics, and technical implementations. These models capture the paradoxical logic of conflict, where more resources do not always translate into greater advantage, and where nonlinear dynamics govern outcomes. To illustrate the approach, this chapter examines RedCyber, a synthetic cyber conflict, demonstrating how game-theoretic methods capture the interdependencies of cyber operations. The chapter concludes with directions for future research on resilience, cros-echelon planning, and the evolving role of AI in cyber warfare.

• Figure 1: A multi-echelon cyber warfare framework depicting the hierarchical structure of cyber conflict across policy, strategic, operational, and tactical levels. The cyber policy level defines long-term objectives through infrastructure development, alliances, and legal-normative frameworks such as the Tallinn Manual. These directives guide strategic planning, where campaigns progress through stages including reconnaissance, disruption, escalation, sustained assault, and strategic messaging. At the operational level, attacker and defender strategies evolve dynamically across stages indexed by $k$. Tactical actions (e.g., $T_1 \rightarrow T_2 \rightarrow T_3$) represent concrete maneuvers whose aggregated effects determine operational and strategic outcomes. The framework emphasizes cross-echelon interdependence: higher-level decisions shaping lower-level actions and realized outcomes feeding back to adjust strategy and policy, forming a coherent hierarchical meta-game.
• Figure 2: Recursive interdependencies among equilibria across policy, strategic, operational, and tactical levels of cyber warfare. Forward (blue, solid) arrows represent constraints and decisions propagated downward across echelons, while backward (red, dashed) arrows capture upward feedback effects. The technical equilibrium $E_{\text{technical}} = \theta^*$ influences all levels directly. A coherent warfare equilibrium emerges only when both forward constraints and backward feedback are jointly satisfied, ensuring cross-echelon consistency.

Each node illustrates a phase of the campaign, policy preparation, reconnaissance, disruption, escalation, and sustained operations, with the deception index $\lambda$ and technology lever $\theta$ annotated as cross-cutting parameters that shift detection latencies and feasible action sets in $T(\cdot)$.
