The core component of an Industrial Control System (ICS) is often aProgrammable Logic Controller (PLC) combined with various modules. In suchsystems, the communication between devices is mainly based on the Modbusprotocol, which was developed by Modicon (now Schneider Electric) in 1979 as anapplication-level communication protocol and has become a de facto standard forICS for the past 40 years. Modbus TCP is a variant of this protocol forcommunications over the TCP/IP network. However, the Modbus protocol was notdesigned with security in mind, and the use of plaintext transmissions duringcommunication makes information easily accessible to the attackers, while thelack of an authentication mechanism gives any protocol-compliant device theability to take over control. In this study, we use the eBPF technology toshift the process of protocol change to the lower level of the operatingsystem, making the change transparent to the existing software, and enhancingthe security of the Modbus TCP protocol without affecting the existing softwareecosystem as much as possible.
