摘要
针对未改进系统未在软件部分设立预警机制而导致系统预警效果差的问题,提出了基于B/S架构的电力网络安全智能预警系统设计。以B/S体系结构为基础设计系统硬件,设计蜜罐宿主机结构,在eth3接口更改系统恶意样本文件。通过Linux中心配置syslog服务器,捕获日志信息。采用模块化结构,设计系统功能,确定电力平衡指数预警指标,计算分解后网络安全信息小波熵,提取网络安全状态特征。设定预警条件、修改数据,完成预警流程设计。由系统调试结果可知,该系统预警效果好,为电力网络安全提供保障。
In view of the problem that the early warning mechanism is not set up in the software part of the unimproved system and the early warning effect of the system is poor,the design of an intelligent early warning system for power network security based on B/S architecture is proposed.Design the system hardware based on the B/S architecture,design the honeypot host structure,and change the system malicious sample file on the eth3 interface.Configure the syslog server through the Linux center to capture log information.Adopt modular structure,design system functions,determine early warning indicators of power balance index,calculate wavelet entropy of network security information after decomposition,and extract network security status features.Set early warning conditions,modify data,and complete early warning process design.It can be seen from the debugging results of the system that the early warning effect of the system is good,which provides guarantee for the power network security.
