摘要:

为了更合理地分析和评估网络安全态势,提出了一种基于云模型的网络安全态势分析方法,给出了算法实现的基本思想、关键技术和实现步骤。在标准概念云的生成过程中,提出一种改进的未知确定度的逆向云生成算法,并证明了该算法对云数字特征的估计偏差更小,精度更高。最后,通过kddcup99数据集进行仿真实验。结果表明,该方法兼顾了风险分析的模糊性和随机性,可以较好地对网络安全态势进行分析和预测,为采取正确的预防措施提供了有力参考。

Abstract:

In order to analyze and evaluate the risk of network security more reasonably, a cloudmodel based method for network security analysis was proposed. The main ideas, key technical and implementation steps of the method were given. The standard clouds were generated using improved backward cloud algorithm with unknown certainty. The improved algorithm with smaller deviation was also proved. Finally, Kddcup99 data set was used to simulate. The experimental results show that the proposed method retains the uncertainty of risk analysis. It provides a strong reference to adopt appropriate preventive measures.
