Description:
TP309; 为有效识别关键业务系统并评估业务系统对全业务流程造成的安全风险和影响,提出一种全业务流程关键业务系统识别模型.首先,建立业务流程关联树与业务流程关联网络,得到评价属性矩阵与系统关联度矩阵.其次,由评价属性矩阵与系统关联度矩阵构造关联评价属性矩阵,改进优劣解距离法(technique for order preference by similarity to an ideal solution,TOPSIS)中加权方法和相对接近度计算方法,基于TOPSIS改进方法计算业务系统的重要性系数,进而识别全业务流程中关键业务系统.最后,评估业务系统发生信息安全事件时对全业务流程连续性的影响.实验结果表明,该方法能够准确地识别出全业务流程中的关键业务系统,有助于高效评估业务系统对全业务流程造成的影响.
