Research on metrics of network survivability
网络抗毁性测度研究

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.
