摘要
针对网络抗毁性测度问题,依据抗毁性三原则——阻挡、识别和恢复,提出了多维网络抗毁性测度提取方法,该方法综合运用了多种抗毁性分析技术,结合实际验证筛选,为提炼抗毁性测度提供了有效途径;提出了三层树状结构的网络抗毁性测度集,为抗毁性测度提供了可行的分类参考;最后,提出了抗毁性测度度量方法并给出了其形式化描述,实现不同类型抗毁性测度值的获取。分析表明,提出的网络抗毁性测度提取方法、测度集合和度量方法具有良好的一致性和可行性。
Metrics of network survivability is a challenge for network security research. This paper presented a new method to find out metrics of network survivability on multi-dimensionality, in accroding with three tenets of survivability： （1）resistance to intrusions, （2）recognition of intrusion effects, （3）recovery of services despite successful intrusions. Presented a metric set of network survivability organized with three-layers structure, which showed a feasible taxonomy for metrics. Presented a new approach to measure network surivivability, i.e. getting value of metrics of network surivivability, for different situations. Finaly, discussed the consistency and feasibility of the three research results above.
