Python网络安全工具：ARP欺骗、ICMP洪水和TCP攻击检测

本项目是一个使用Python编写的网络安全工具，可以帮助您检测和防御常见的网络攻击，例如ARP欺骗、ICMP洪水攻击和TCP攻击。此外，该工具还提供网络扫描功能，可以帮助您识别网络上的活动主机。

功能

  • ARP欺骗检测: 检测网络上的ARP欺骗攻击，并识别攻击者的IP地址和MAC地址。
  • ICMP洪水攻击检测: 检测针对您的设备的ICMP洪水攻击。
  • TCP攻击检测: 检测针对您的设备的TCP攻击，例如SYN洪水攻击。
  • 网络扫描: 扫描您的网络并识别活动主机及其MAC地址。

使用的技术

  • Scapy: 一个强大的Python库，用于处理网络数据包。
  • Tkinter: Python的标准GUI库，用于创建用户界面。
  • netifaces: 用于获取网络接口信息的Python库。

如何使用

  1. 确保您已安装所需的Python库：Scapy、Tkinter和netifaces。
  2. 将代码保存为Python文件（例如，network_security_tool.py）。
  3. 运行该文件： python network_security_tool.py
  4. 该工具将启动，并显示一个简单的用户界面。
  5. 点击“开始”按钮开始检测网络攻击和扫描网络。
  6. 点击“停止”按钮停止检测和扫描。

注意

  • 您需要将代码中的网络接口名称（'ens33'）更改为您正在使用的网络接口的名称。
  • 网络扫描功能会将扫描结果保存到名为“network_scan.txt”的文件中。
  • 该工具仅用于教育和测试目的。请勿将其用于非法活动。
