| Abstract: | This thesis explores the impact of interactive and gamification elements on effectively communicating qualitative attack trees to non-expert stakeholders. The challenges identified that possible hinder the effective explanation of attack trees include: a lack of contextual information, the use of technical jargon, insufficient emphasis on risk severity, and an overwhelming structure of attack trees that can lead to cognitive overload. An engagement framework was developed to guide design choices that enhance the effective communication. To address these challenges, a gamified interactive visualization was created. The analogy of locks on doors that must be opened with keys is used to help users map this familiar relationship onto the various logic gate material in the attack tree. This design incorporated various gamification elements, such as a leaderboard for displaying minimal attack sets, a challenge to find the minimal attack set by selecting keys for doors, UI elements providing instant feedback, a visually appealing environment, and a movable character to boost engagement and understanding among non-expert stakeholders. The results showed that the experimental group had a better understanding of compared to the control group, and participants found the prototype engaging. Some design flaws were identified, suggesting areas for improvement to further enhance engagement. |
