The document proposes a SCADA testbed environment consisting of four main components: 1) A SCADA laboratory for performing attacks and defenses, 2) An INTERROGATOR architecture to capture network traffic data, 3) A data warehouse to store captured SCADA cyber attack data, and 4) Expanding the environment to the Biosphere 2 facility to create a larger testbed and user facility. The objectives are to collect a variety of SCADA attack data, evaluate vulnerabilities in industry systems, and provide a resource for researchers to analyze stored attack data and test mitigation techniques.
