越来越多的控制系统网络安全事件表明，来自商业网络、互联网以及其他因素导致的控制系统网络安全问题影响工业稳定生产安全。工业控制系统协议在设计之初并未考虑足够的安全需要，导致其存在严重的安全漏洞。本文以Modbus协议为例，分析其存在的安全问题，提出了在防火墙中实现对数据进行深度包检测的方法，设计了相应的验证实验，证明可以通过该方法对协议提供安全保护。

More and more the control system network security events have occurred, which demonstrated the commercial network, the Internet, as well as other factors affect industrial stable performance safety because of their control system network security issues. Industrial control system protocol now suffers seriously from many Security vulnerabilities, because it lacked enough consideration for Security needs when firstly designed. Based on the Modbus Protocol, the paper analyses the existing security issues, proposes a new method to inspect data for deep packet and designed the corresponding experiment for verification. The result has been proven that this new method can provide Safety Protection for the Modbus Protocol.
