中文摘要:
      针对传统的网络安全态势评估方法一直存在评估偏差较大的问题,为了准确分析网络安全状况,提出一种新的多阶段大规模网络攻击下的网络安全态势评估方法。首先根据多阶段大规模网络攻击下的网络安全多数据源的特点,建立基于信息融合的多阶段大规模网络攻击下的网络安全态势评估模型;然后对大规模网络攻击阶段进行识别,计算网络攻击成功的概率和网络攻击阶段的实现概率;最后利用CVSS中的3个评价指标对网络安全态势进行评估。实例分析证明,所提方法更加符合实际应用,评估结果准确且有效。
英文摘要:
      For the traditional network security situation assessment method,there is always a problem of large evaluation bias.In order to accurately analyze the network security situation,a network security situation assessment method of multi-stage large-scale network attack under the new network security was proposed.Firstly,based on the characteri-stics of multiple data sources under multi-stage large-scale network attack,the network security situation assessment model of multi-stage large-scale network attack was established based on information fusion.Next,large-scale network attack stage was identified,and the success probability of network attack and implementation probability of network attack phase were calculated.Finally,three indexes in CVSS was used for network security situation assessment.The exam-ple analysis shows that the proposed method is more suitable for practical application,and the evaluation results are accurate and effective.
