This thesis describes the development of a prototype security hardened field device (such as a remote terminal unit) based on commodity hardware and implementing a previously developed security architecture. This security architecture has not been implemented in the past due to the difficulty of providing an operating system which meets the architecture's isolation requirements. Recent developments in both hardware and software have made such an operating system possible, opening the door to the implementation and development of this new security architecture in physical devices attached to supervisory control and data acquisition (SCADA) systems. A prototype is developed using commodity hardware selected for similarity to existing industrial systems and making use of the new OKL4 operating system. Results of prototype development are promising, showing performance values which are adequate for a broad range for industrial applications.
