Graph theory has emerged as a fundamental mathematical framework for modeling, analyzing, and securing complex network infrastructures in cybersecurity. This paper explores the comprehensive applications of graph-theoretic models in network defense systems, examining how vertices, edges, and graph properties can effectively represent network topologies, threat propagation paths, and defensive strategies. Through systematic analysis of six key areas including network topology modeling, attack graph generation, intrusion detection systems, vulnerability assessment, threat intelligence, and advanced defense mechanisms, this research demonstrates the critical role of graph theory in modern cybersecurity frameworks. The paper synthesizes recent research findings and presents comparative analyses of various graph-based approaches, highlighting their strengths, limitations, and practical implementations in real- world network defense scenarios.
