摘要
为定量认识IMS网络攻击的影响,提出了一种基于模糊综合评价的IMS网络攻击后果评估方法。通过分析可能的攻击流程建立了相应的攻击因素树,引入层次分析法计算评价因素的权值,然后利用模糊综合评价法对IMS的攻击后果进行综合评估。为了降低由单一模糊算子特点带来的评估偏差,选取了几种不同特点的算子分别进行评估,并取其均值为最终评价结果。实例验证了该评估方法能有效地区分不同攻击方式带来的攻击后果,能够为IMS网络的安全防护提供一定的参考。
For the purpose of a quantitative understand for IMS network＇s attack effect, this paper introduced an evaluation method for IMS＇s attack effect based on fuzzy comprehensive evaluation. It constructed the attack index tree on the basis of analyzing the possible attack flow, and introduced analytic hierarchy process to compute the indexes＇ power, and made comprehensive evaluation for IMS attack effects using the fuzzy comprehensive evaluation. To reduce the warp brought by the single fuzzy operator＇s properties, it selected several operators with different properties to evaluate and took the mean as the finally result. Finally, the examples validate the evaluation method is able to distinguish the attack effects resulted by different attack methods effectively, and can provide a reference to the security of IMS.
