#smod smod 是一个模块化框架，包含了你对 Modbus 协议进行渗透测试所需的各类诊断与攻击功能。它使用 Python 和 Scapy 实现了完整的 Modbus 协议。该软件可在 Linux/OSX 系统上、python 2.7.x 环境下运行。
##摘要 近年来，基于 SCADA（过程控制网络）的系统已从专有的封闭网络逐步转向开源解决方案和启用 TCP/IP 的网络。这使得它们面临与传统计算机网络相同的安全漏洞。
Modbus/TCP 协议被用作参考协议，以展示测试床在对电力系统协议实施网络攻击时的有效性。选择 Modbus/TCP 具体有以下原因：
你可以使用该工具对 Modbus 协议进行漏洞评估。
