网络抗拒绝服务攻击性能的集对评估方法

杭攻击测试是进行系统安全测评的重要手段之一，对网络系统的抗拒绝服务攻击性能评估是杭攻击测试需要解决的一个关键问题。基于集对原理提出了网络杭攻击性能评佑的新方法—集对评佑法。系统地给出了网络抗攻击性能集对评佑法的思路和步骤，考虑等级标准边界的模糊性，提出了采用模糊分析法确定同异反联系度，提出了基于粗糙集属性重要性的指标权重确定方法。最后通过实验验证了集对评估法的有效性和可靠性。

Set Pair Analysis Method for Evaluating Denial of Service Attack Resistance Ability

Attack resistance test(ART) is an important security evaluation method and evaluating the system's attackresistance ability becomes a new domain of ARh. A new evaluation method of DoS attack resistance ability based on setpair was presented. The process of systematic analysis DoS attacks resistance ability was broadly put forward. Identity-discrepancy-contrary connection numbers were confirmed by fuzzy method. Using rough set theory, the nonlinear combi-nation weight of evaluation indices was established. A simulation example shows that the approach is brief and effective.
