This paper responds to the need to understand the nature of SCADA systems security concepts, their important role in the Australian nation’s critical infrastructure protection and highlights the necessity of this as a specialist engineering course within a systems engineering program. It defines the nature of the field and the roles and qualifications of system engineering practitioners who serve in the field. It emphasizes the role of the specialist course within the tertiary program that produces potential systems engineering specialists with the knowledge required to achieve robustness and resilience of critical infrastructure systems and services.
