In today’s digital world, everyone is prone to cyber threats, especially teenagers and budding professionals. Students in high schools today are not exposed to cybersecurity concepts, and thus do not completely understand the consequences of their activities online. While there are programs and courses available to address this knowledge gap, we see fewer enrolments due to their lack of interest in the area, little to no exposure to potential career prospects, and extensive homework assignments. Moreover, several studies show that students learn better with interactive games and hands-on activities since they allow them to explore and learn out of curiosity. To this effect, we present AnSecLearn – a story-based game for learning about cybersecurity and threat mitigation and avoidance techniques. The game immerses players in the daily life of a high school student, where they navigate realistic scenarios involving cybersecurity threats such as phishing attacks, malicious apps, unsecured networks, and impersonation attacks. Throughout the game, players make informed decisions to mitigate the risks, progressing through levels that focus on real-world cybersecurity dilemmas, while earning rewards along the way. This ensures that lessons are relevant, practical, and engaging. Our design process involved identifying key cybersecurity concepts, crafting dynamic story-driven scenarios, and implementing an active reward system to reinforce positive learning outcomes. The game was developed on Unity and is compatible with smartphone operating such as Android and iOS providing them an opportunity to play and learn at their own time. AnSecLearn has the potential to teach best practices and concepts that promote long-term retention, ultimately contributing to a safer digital landscape for the community.
