电子邮件网络中的传播型攻击是非常严重的网络安全问题.研究界提出了很多种网络免疫方法来解决这个问题,基于节点介数( node betweenness,NB)的方法是目前最好的方法.综合利用电子邮件网络的网络拓扑与传播型攻击的传播参数设计了一种网络免疫方法.在生成的电子邮件网络拓扑模型以及Enron电子邮件网络真实拓扑数据的仿真表明,该方法比NB方法更有效.在某些仿真场景下,本免疫方法能够比NB方法达到50％的改进.%Epidemic attacks in email networks are serious network security problems. Many immunization strategies have been proposed to address these problems. The node betweenness ( NB) strategy is the state of the art. This paper designed an even better immunization strategy than the NB strategy. It was based on both the epidemic spreading parameters and the email network topology. In all of the simulations in synthetic networks and the Enron email networks, the new immunization strategy is consistently better than the NB strategy. In some of the simulation scenarios, there is almost a 50% improvement than the NB strategy.
