摘要
为保障信息网络系统在遭受攻击和破坏时,仍能够稳定、可靠地提供服务,必须关注系统可生存性评估问题。本文采用德尔菲法(Delphi)对影响系统生存性的各种因素进行了深入分析,确立了信息网络系统可生存性评价指标体系,在此基础上,考虑到该评估问题的复杂性、不确定性,提出一种基于模糊数学方法的评估模型,通过实例分析验证了方法的可行性,为完善信息网络系统可生存性评估提供了新的思路与方法。
In order to assure that Information network system could steadily and reliably deliver essential services in face of attack,the survivability evaluation of the system must be concerned.The various factors of influencing network System Survivability are deeply studied by using Delphi method in this paper,and the comprehensive assessing index system of Information Network system is constructed.Base on this and considering the uncertainty and complexity of Survivability Evaluation of Information Network System,a proposed model was presented for Survivability Evaluation based on the fuzzy mathematics.A case of evaluating Survivability proves the rationality of way which can provide the new idea and method to improve the result of evaluating Survivability of Information Network System.
