An Efficient Survivability Hierarchy Analysis Model for Networked Information System
Lejun Zhang, Guo Lin, Yang Jie Wu, Wei Wang, Yongtian Yang · 2007
This paper presents an efficient survivability hierarchy analysis method for networked information system. In the hierarchical model, the top level is the survivability of system; the second is the survivability of essential service; the third is the survivability of atomic module; the lowest one is vulnerability. With the help of attack graph, the survivability (3R+A) is quantified according the records of the Qos before and after attack. Key words: survivability, hierarchical model
