论文针对广域网环境下网络安全态势值的计算问题,建立了一个实际可操作的广域网态势值计算模型,并提出了一种统计分析算法,该算法通过计算各种测量值的Q值,分析其历史分布。转换成对应T2值,来使得态势值具有反映一段时间内安全趋势的特性。
This paper deals with the problem of generating network security situation value in WAN environment. A practical, operable new model is proposed. This model adopts a statistical analyzing algorithm to calculate Q value of various measured values. In analyzing its historical distribution, Q value can be converted to certain T2 value, which enable the situation value to reflect the trend of network security situation in recent period.
