MiniCPS is a framework designed for real-time simulation of Cyber-Physical Systems (CPS) that provides comprehensive support for both physical process simulation and control device emulation. Built on top of the mininet network emulator, the framework enables researchers and security professionals to create realistic industrial control system environments for testing and analysis purposes. The tool supports network emulation capabilities, allowing users to simulate complex industrial network topologies and communication protocols commonly found in operational technology environments. MiniCPS includes functionality for simulating physical processes and control devices, making it suitable for studying the interaction between cyber and physical components in industrial systems. The framework has been developed by the SCy-Phy group from Singapore University of Design and Technology (SUTD) and has been featured in multiple academic research papers focusing on CPS security. The tool provides a foundation for security research, training, and honeypot development in industrial control system environments, supporting both educational and research applications.
