【摘要】：基于網(wǎng)絡系統(tǒng)的安全需求,針對樹形網(wǎng)絡拓撲結構,提出一種網(wǎng)絡系統(tǒng)危險指數(shù)的計算方法。根據(jù)各節(jié)點存在的漏洞,用優(yōu)劣解距離法(TOPSIS)可以得出各節(jié)點的危險指數(shù),結合其在系統(tǒng)中所占的權重,計算出整個網(wǎng)絡系統(tǒng)的危險指數(shù),為安全事件的提前防御和后期補救工作提供參考。
[Abstract]:Based on the security requirements of the network system, a method for calculating the hazard index of the network system is proposed, aiming at the topology structure of the tree network. According to the loopholes existing in each node, the hazard index of each node can be obtained by the method of separation between good and bad, and the risk index of the whole network system can be calculated by combining the weight of each node in the system, and the risk index of the whole network system can be calculated by (TOPSIS). To provide a reference for early defense and later remediation of security incidents.
