基于Petri网的APT攻击模型生成方法

在严峻的APT(Advanced Persistent Threat)攻击防御背景下,针对现有网络攻击建模方法无法反映APT攻击的攻击特点,建立了基于Petri网的APT攻击模型。借助Petri网,首先针对APT攻击的特点及生命周期,建立APT攻击的基本Petri网模型；然后设计并实现APTPN(Advanced Persistent Threat Petri Nets)模型的生成算法,针对具体的APT攻击生成其完整的攻击路径；最后,实验通过模拟极光攻击验证了算法的有效性及正确性。

Modeling Method for Advanced Persistent Threat Based on Petri

Against the background of severe APT attack defense, aiming at the fact that the existing network attack modeling methods can not reflect the attack features of APT attacks, an APT attack model based on Petri nets is established. With Petri nets, the basic Petri net model of APT attacks is first established according to the characteristics and life cycle of APT attacks. Then, the algorithm of generating APTPN (Advanced Persistent Threat Petri Nets) model is designed and implemented to generate its complete attack path against a specific APT attack Finally, experiments verify the effectiveness and correctness of the algorithm by simulating auroral attacks
