A revolutionary development in machine-to-machine communications, the "Internet of Things" (IoT) is often characterized as an evolution of Supervisory Control and Data Acquisition (SCADA) networks. SCADA networks have been used for machine-to-machine communication and controlling automated processes since before the widespread use of the Internet. The adoption of open internet protocols within these systems has created unforeseen security vulnerabilities. In this paper we detail the Cyber-SCADA Evaluation Capability (C-SEC), a US Department of Defense research effort aimed at securing SCADA networks. We also demonstrate how the C-SEC framework could enhance the security posture of the emerging IoT paradigm. 421forts in SCADA and IoT security, with a focus on security models and test beds. Finally, concluding remarks are offered.
