A High-interaction Physics-aware ICS Honeypot for Industrial Environments

Industrial Control Systems (ICSs) are control systems that automate and control industrial processes. ICSs have a high-security risk since most of them are connected to the Internet for remote monitoring and controlling purposes. Compromising ICS can disrupt critical infrastructure supplies, such as water supply, power supply, transportation systems, and manufacturing systems. Programmable Logic Controllers (PLCs) are special computers used in ICSs. Many PLCs do not have built-in security systems. Many ICS application layer protocols are not designed with security in mind. Therefore, external security systems are needed to protect ICSs from cyber-attacks. Identifying the vulnerabilities, malware, and attacking patterns is useful in designing defense-in-depth security systems for ICSs. Honeypots can be used for research purposes as a way of collecting data and can also be used to protect the systems from attackers. In this paper, we present a high-interaction physics-aware ICS research honeypot that has been extended to a production honeypot using Software Defined Networking.
