摘　　要：使用地址库过滤、防火墙过滤技术存在地址库更新不及时的问题,导致非法接入现象频繁。为了解决该问题,提出了新能源涉网电力监控网络非法接入阻断技术。根据新能源涉网非法接入行为的检测结果,构建非法接入内容的识别与阻断模型。通过搭建终端非法接入监控阻断装置,对不符合要求的终端在网页界面发出预警信号。验证了ID地址之后,绑定用户,实现了移动任务的执行。利用面向TCP协议的连接阻断技术,结合协议栈窗口协议,对不安全数据包的非法流入进行阻断。由实验结果可知,该技术能够阻止不安全数据包流入,保证用户能够精准找到想要搜索的页面。The address library is not updated in time by using address library filtering and firewall filtering technology,which leads to frequent illegal access.In order to solve this problem,a new energy network⁃related power monitoring network illegal access blocking technology is proposed.According to the detection results of new energy networked illegal access behavior,the identification and blocking model of illegal access content is built.By building a monitoring and blocking device for illegal access of terminals,early warning signals will be sent out on the webpage interface for terminals that do not meet the requirements.After verifying the ID address,the user is bound to realize the execution of the mobile task.Using the TCP protocol oriented connection blocking technology,combined with the protocol stack window protocol,to block the illegal inflow of unsafe packets.The experimental results show that the technology can prevent unsafe data packets from flowing in and ensure that users can accurately find the page they want to search.
