摘要:

提出了一种基于网络图论模型的威胁态势分析方法。定义了图中邻接点的攻击代价,并采用多属性效用理论计算其效用值。对图中的边赋予代表攻击代价的权,利用最短可达路径算法分析了节点的威胁态势。实例表明,该方法简捷有效,有助于优化安全防护策略。

Abstract:

A new threat situation analysis based on the network graph model is presented. The attack cost of adjacent nodes is defined, and the multi-attribute utility theory is adopted to quantify its value. The graph edges are endowed with the weight representing the attack cost, and the threat situation of network node is also analyzed by the shortest accessible path arithmetic. The case study demonstrated that the method is concise and effective, that will help to optimize the safety strategy.

Key words: network security, graph theory model, attack cost, threat road
