| Summary: | 碩士 === 國立臺灣大學 === 資訊工程學研究所 === 107 === Sharing cyber threat information between organizations is important to amplify the defense against sophisticated cyber attacks. However, the standard format for describing and exchanging cyber threat information is difficult to explore without the help of visualization techniques. As the head-mounted display (HMD) technology becomes more mature, immersive visualization approaches have the potential to provide better experiences. In this work, we present an interactive system for exploring cybersecurity information in the immersive environment, which utilizes the C# job system and entity component system (ECS) architecture to visualize tens of thousands of nodes and edges with a high framerate (>90 FPS). We collaborated with cybersecurity experts to design several interaction techniques based on their insights into the analysis of cyber threat information. Finally, we conducted two user studies. The results show that participants could find essential information faster using our system compared to the 2D graph visualization tool, and the system usability and user workload were also better. When exploring the cybersecurity data which has been arranged by cybersecurity experts, users could achieve similar performance using our virtual reality (VR) system and the desktop-based counterpart. Nevertheless, immersive visualization caused a lower mental workload.
