摘要:

针对指标选取的主观性带来的评估结果准确率低、实时性较差等问题,提出了基于因子分析法和主成分分析法的网络安全态势评估指标优化模型。该模型可以用一组具有较强独立性的综合变量来描述原有的指标体系,从而减少网络安全评估时的计算量。实验表明,模型在不影响准确率的情况下能够得出较为实时的评估结果。

Abstract:

Low accuracy and poor real-time performance are two issues in network security situation evaluation (NSSE). We present an index optimization model for network security situation evaluation based on factor analysis and principal component analysis. The model can deduce a class of comprehensive variables with strong independence to describe the existing index system. Experimental results show that this optimization can obtain more realtime evaluation results without accuracy loss for NSSE.
