摘要
Modbus TCP协议是基于Modbus串行协议与TCP/IP协议的结合而形成的一种工业以太网通信协议,自 1999 年提出以来,已广泛应用于工业控制系统(Industrial Control System,ICS).然而,该协议最初设计时并未考虑现代网络安全需求,存在诸多安全漏洞,易成为攻击者的攻击目标,严重威胁工控系统的安全性.因此,对Modbus TCP协议进行安全增强研究具有重要意义.本文综述了基于Modbus TCP协议的主要安全增强方案,详细分析了其技术实现方法及适用场景,并对不同方案的优缺点进行了系统比较,旨在为Modbus TCP协议的安全防护提供有效的解决方案和研究思路.这些安全增强方案的实施,可以有效提高Modbus TCP协议在工控系统中的抗攻击能力,从而提升工控系统的整体安全性.
Abstract
Modbus TCP protocol is an industrial Ethernet communication protocol based on the combination of Modbus serial protocol and TCP/IP protocol,which has been widely used in industrial control systems(ICS)since it was proposed in 1999.However,because the protocol was originally designed without considering modern network security requirements,it has many security vulnerabilities,which is easy to become the target of attackers and seriously threatens the security of industrial control systems.Therefore,the research on the security enhancement of Modbus TCP protocol is of great significance.In this paper,the main security enhancement schemes based on Modbus TCP protocol are reviewed,their technical implementation and application scenarios are analyzed in detail,and the advantages and disadvantages of different schemes are systematically compared,aiming to provide effective solutions and research ideas for the security protection of Modbus TCP protocol.The implementation of these security enhancement solutions can effectively improve the attack resistance of the Modbus TCP protocol in industrial control systems,thereby enhancing the overall security of the ICS.
