Guest Editorial Special Issue on Secure Embedded IoT Devices for Resilient Critical Infrastructures

The Internet of Things (IoT) creates new technological opportunities for a wide range of systems, such as industrial control systems, smart power grids, vehicular networks (VNs) and intelligent transportation systems, body area networks and healthcare monitoring and control systems and smart homes. At the same time, IoT also increases the threat surface for potential adversaries targeting critical interconnected systems that may depend on embedded IoT systems, such as supervisory control and data acquisition (SCADA) systems. At this point, attackers could take advantage from the incorporation of the paradigm to exploit new security gaps, probably caused by unforeseen interoperability and adaptability problems. Indeed, the deployment of Internet-enabled embedded devices that are distributed over major critical domains may create indirect and nonobvious interconnections with the underlying critical infrastructures (CIs). There is a need to further explore the security issues related to IoT technologies and to assure the resilience of CIs against advanced IoT-enabled attacks. The focus of this special issue is therefore to provide readers with the latest advances in securing the interaction between embedded IoT devices and CIs in order to increase their resilience to advanced IoT-enabled threats.
