Analysis and validation of survivability for network service system
摘要
Abstract
In order to analyze the survivability of network service system with redundant components,an attack-resistance-recovery process model was established,and a quantitative assessment method for system survivability was proposed on the basis of the dependency relationship between service and components.The sensitive parameters for the assessed values of survivability and the recovery priority under greedy strategy for the system with different components were analyzed,and the simulation tool was designed with the coloured Petri net.In addition,the effect of attack intensity,attack density and recovery intensity on the system survivability was validated through taking an IPTV network service system as an example.With the proposed method,the operation process of survivable system was modeled as a dynamic process under the parallel action of multiple factors,and the system survivability was validated with the simulation tool.The validation results can provide the referrence for the design of survivable system and the enhancement strategy of survivability.关键词
