针对SSH服务弱加密算法的中间人攻击分析

Analysis of Man in the Middle Attack Against SSH Service Weak Encryption Algorithm

为了降低局域网网络安全风险,解决局域网普遍存在的网络安全热难点问题,通过模拟网络安全问题进行网络安全风险分析是十分必要的。本文提出了一个针对SSH协议的弱加密算法进行网络安全风险分析的方案,对局域网中存在的热难点问题,通过布置小型局域网进行隐患复现,对解析网络安全问题的成因及风险提出了具体的操作方法。实践结果表明,采用该方案可以有效降低局域网网络安全风险,保障局域网网络平稳运行。

In order to reduce the risk of LAN network security and solve the hot and difficult problems of LAN network security,it is necessary to analyze the network security risk by simulating the network security problems.This paper puts forward a scheme of network security risk analysis based on the weak encryption algorithm of SSH protocol.For the hot and difficult problems existing in the LAN,this paper analyzes the causes and risks of the network security problems by arranging a small LAN to reproduce the hidden dangers.The practice results show that this scheme can effectively reduce the security risk of LAN network and ensure the smooth operation of LAN network.
