Factors Impacting Resilience of Internet of Things Systems in Critical Infrastructure
share
Internet of Things (IoT) systems are recently being employed in various types of critical infrastructure, including integrated rescue systems, healthcare, defence, energy and other fields. Recently, the security and safety of IoT systems, in general, has been questioned by a number of studies. Raised concerns do not relate to the IoT technology in principle but to poor engineering practices that are mostly preventable. In critical infrastructure, demand for safety and security is strongly present and justifies a discussion about the general resilience of IoT systems. In this context, resilience includes system resistance to cyberattacks and its stability to operating conditions and system reliability and safety in terms of present flaws. In this paper, we discuss relevant factors impacting the resilience of IoT systems in the critical infrastructure and suggest possible countermeasures and actions mitigate the potential effects of these factors. Contrary to the previous work, an unique critical system Model-based Testing viewpoint is taken in this analysis.
