Critical Infrastructures are defined as “assets, systems or part thereof which are essential for the maintenance of vital societal functions, health, safety, security, economic or social well-being of people, and the disruption or destruction of which would have a significant impact as a result of the failure to maintain those functions.” Critical Infrastructures refer to a multitude of sectors, including energy, manufacturing, transportation, healthcare, and public safety. Systems deployed within these sectors integrate both information technologies and operational technologies, being commonly reliant on legacy industrial control and cyberphysical systems. Nevertheless, novel disruptive and enabling information and communication technologies are increasingly integrated, increasing connectivity and interdependencies, thus presenting security professionals with significant challenges in maintaining and enhancing the security and resilience of such infrastructures. This Special Issue invites submissions that present innovative ideas, proof of concepts, use cases, and results from a variety of topics relevant to critical infrastructure cybersecurity and resilience, including (but not limited to) the following ones:

Security Governance

Security policies
Risk analysis and management
Vulnerability assessment and metrics
