【摘要】 提出一种新的网络攻击图(NAG)自动生成及优化方法,针对NAG的状态空间爆炸问题,将其分为子攻击图和父攻击图。子攻击图描述从攻击发起主机到目标主机的具体攻击方案,父攻击图描述攻击者在网络主机间的权限转移过程。该方法通过简化NAG的结构减小其复杂度。更多还原

【Abstract】 This paper presents a new approach to automatic construction and optimization of the Network Attack Graph(NAG). For solving scalability problem of the NAG, a hierarchy has been adapted for the network structure that can be divided into attack subgraph and attack supergraph. The attack subgraph describes concrete attack scenarios from the source host to the destination host. The attack supergraph described the attacker’s privilege transition processing. This approach reduces the complexity of NAG by simplifying the structure of it.更多还原
