In support of the US Army Research Laboratory ARL mission to conduct cybersecurity research to protect Industrial Control Systems ICS, the ARL Sustaining Base Network Assurance Branch SBNAB constructed a Supervisory Control and Data Acquisition SCADA hardware testbed to simulate the network traffic between human machine interface HMI and programmable logic controller PLC components. The HMI and PLC components were instantiated with software and installed in multiple virtual machines VMs to emulate 6 conceptual manufacturing plant processes. Two experiments were conducted Validate the virtualized network performance by creating and capturing HMI PLC network traffic over a 24-h period in the virtualized network and inspect the packets for errors. Test the interoperability of physical network elements with the virtualized network. In this test, a simulated threat actor used a laptop computer to connect to the virtualized production network and send malicious Modbus network commands to create a manipulation of view attack. The results of both experiments are PASS. The experiments validated the capability to establish a SCADA hardware testbed using virtualization and this infrastructure is now part of the ARL SBNAB US Army Cyber Analytics Laboratory ACAL.
