Critical National Infrastructures (CNIs) are vital assets for public safety, economic welfare, and the national security of countries. Vulnerabilities of critical infrastructures have increased with the widespread use of information technologies. As CNIs are becoming more vulnerable to cyberattacks, their protection becomes a significant issue for any organization as well as nation. The risks to continued operations from failing to upgrade aging infrastructure or not meeting mandated regulatory regimes are considered higher given the demonstrable impact of such circumstances. Due to the rapid increase of sophisticated cyber threats targeting critical infrastructures with significant destructive effects, the cyber security of CNIs has become an agenda item for academics, practitioners, and policy makers. A holistic view which covers technical, policy, human, and behavioral aspects is essential to handle cyber security effectively. Moreover, the ability to attribute crimes to criminals is a vital element of avoiding impunity in cyberspace. In this workshop, both research and practical aspects of cyber security considerations in critical infrastructures are of interest. Aligned with the interdisciplinary nature of cyber security, authors from academia, government, and industry are welcome to contribute. We seek original and high-quality submissions on, but not limited to, one or more of the following topics: § Cyber security of industrial control systems; § Cyber security modeling and simulation; § Cyber security of complex and distributed critical infrastructures; § Cyber threat modeling and analysis; § Safety-security interactions; § Behavioral modeling; § Network security and protocols; § Security, privacy, and legal issues of big data and the Internet of Things; § Cyber threat intelligence; § Situational awareness; § Attack modeling, prevention, mitigation, and defense; § Critical infrastructure security policies, standards and regulations; § Vulnerability and risk assessment methodologies for distributed critical infrastructures; § Risk management and cyber insurance; § Simulation and test beds for the security evaluation of critical infrastructures; § Resiliency and security of cyber systems; § Cyber security and privacy policy; § Hardware security solutions; § Incident response; § Encryption, authentication, availability assurance; § Human awareness and training; § Intrusion detection; § Trust and privacy; § Secure communication protocols; § Malware analysis; § Blockchain and ZKPs Important Deadlines Papers due: 15 March, 2025 Acceptance notification: 15 April, 2025 Camera-ready version due: 23 April, 2025 SUBMISSION LINK: https://edas.info/N33085 REGULAR PAPERS Regular papers submissions may be up to 10 pages in length (including figures and references), formatted in two-column IEEE conference style with font size 10 points or greater. See IEEE Manuscript Templates for Conference Proceedings. WORK IN PROGRESS PAPERS WIP (Work-in-progress) papers provide a peer-reviewed forum for late-breaking or preliminary research results, giving an opportunity for researchers and practitioners to present and demonstrate their recent research and obtain feedback from their peers in a poster session. Work-in-progress papers submissions may be up to 4 pages in length (including figures and references) and must have the prefix “WIP:” in the paper’s title.
