Cybersecurity is exponentially growing, evolving, and expanding in all its dimensions. New security risks emerge with the continuous increase of Internet interconnections and the Internet of Things development. Cyberattacks endanger individuals, companies, and vital public services and infrastructures. Confronted with spreading and evolving cyber threats, organizations and individuals need to catch up in defending their systems and networks, and they often need to implement and effectively use basic cybersecurity and privacy practices and technologies. The 8th International Conference on HCI for Cybersecurity, Privacy, and Trust (HCI-CPT) intends to help, promote and encourage research in this field by providing a forum for interaction and exchanges among researchers, academics, and practitioners in the fields of HCI and cyber security. The Conference addresses HCI principles, methods, and tools to address the numerous and complex threats which put at risk computer-mediated human activities in today’s society, which is progressively becoming more and more intertwined with and dependent on interactive technologies.
