摘　　要：智能配网在调度异常内容的分类与处理过程中,过滤时间长、异常内容过滤量低,导致过滤效果粗糙且安全性不高。针对这个问题,提出一种基于Netfilter框架的调度命令票异常内容安全过滤方法。分析智能配网中调度命令票中异常内容传输的攻击行为,建立Hessian矩阵判定特征点,提取异常内容传输特征,设计数据包过滤匹配组织结构,建立命令票异常内容安全过滤模型,在Netfilter框架基础上细化过滤流程,完成智能配网调度命令票异常内容安全过滤方法设计。测试结果表明,在不同测试数据集下,训练时间缩短,异常内容过滤量得到提高,提高命令票异常内容安全过滤的细致程度。In the process of classifying and processing abnormal content in intelligent distribution network scheduling,the filtering time is long and the filtering amount of abnormal content is low,resulting in rough filtering effect and low security.This paper analyzes the attack behavior of abnormal content transmission in the scheduling order ticket in the intelligent distribution network,establishes the Hessian matrix to determine the feature points,extracts the abnormal content transmission characteristics,designs the packet filtering and matching organizational structure,and establishes a security filtering model for the abnormal content of the order ticket.Based on the Netfilter framework,the filtering process is refined,and the design of the security filtering method for abnormal content of the intelligent distribution network dispatching order ticket is completed.The test results show that under different test data sets,the training time is shortened,the amount of abnormal content filtering is increased,and the level of security filtering of abnormal content of command tickets is improved.
