Professor Wei Gao's research lab specializes in industrial control system security, focusing on identifying and mitigating cyber threats such as command injection, data injection, and denial-of-service attacks in critical infrastructure networks. The lab develops advanced intrusion detection systems using both standalone and state-based rules to enhance the resilience of SCADA and I/O control protocols like MODBUS, DNP3, and EtherNET/IP. It also explores innovative signal processing techniques, including the combined 3-point method, for high-precision profile measurement with error compensation in scanning systems. The lab's work bridges cybersecurity and precision engineering to ensure the safety, reliability, and integrity of industrial automation systems.

SCADA systems are widely used in critical infrastructure sectors, including electricity generation and distribution, oil and gas production and distribution, and water treatment and distribution. SCADA process control systems are typically isolated from the internet via firewalls. However, they may still be subject to illicit cyber penetrations and may be subject to cyber threats from disgruntled insiders. We have developed a set of command injection, data injection, and denial of service attack
Industrial control system communication networks are vulnerable to reconnaissance, response injection, command injection, and denial of service attacks. Such attacks can lead to an inability to monitor and control industrial control systems and can ultimately lead to system failure. This can result in financial loss for control system operators and economic and safety issues for the citizens who use these services. This paper describes a set of 28 cyber attacks against industrial control systems
