The 6th International Conference on Science of Cyber Security (SciSec 2024) will be held 14-16 August, 2024 in Copenhagen, Danmark. The conference is organized by the Technical University of Denmark(DTU). This new forum was initiated in 2018 and aims to catalyze the research collaborations between the relevant communities and disciplines that can work together to deepen our understanding of, and build a firm foundation for, the emerging Science of Cyber Security. Publications in this venue would distinguish themselves from others by taking or thinking from a holistic perspective about cyber security, rather than a building-block perspective. Each submission will be reviewed by at least 3 reviewers. The program committee plans to select and award a Best Paper and a Best Student Paper.
