复杂网络安全态势评估模型仿真分析

摘要

复杂网络系统的稳定性较差,延迟呈现较大程度的波动,各种网络安全评估数据的融合自律特征呈现高度的非特征化状态.传统的基于自律特征网络安全评估模型在这种状态下,很难对复杂网络完成安全性整体评估.提出了一种新的复杂网络安全态势评估算法.算法通过计算复杂网络安全评估指标的权值系数,构建了一种特征判断矩阵,根据矩阵结果,利用梯度搜索方法,建立适应于复杂网络安全态势的评估模型,从而实现该网络的安全态势评估.实验结果表明,算法进行复杂网络安全态势评估,能够极大地提高复杂网络安全态势评估的准确性,从而为复杂网络安全提供有力的保障.%A new complex network security situation assessment algorithm was proposed in this paper.By calculating the complex network security evaluation index weights coefficients,a feature comparison matrix was developed.Then,according to the result matrix and using the gradient search method,a complex network security situation assessment model was established,which makes the network security situation assessment enable.The experimental results show that the algorithm can greatly improve the accuracy of complex network security situation assessment,which provides a strong guarantee for complex network security.
