Game based education is becoming more and more popular. This is because game based education provides an opportunity for learning in a natural environment. Phishing is an online identity theft, which attempts to steal sensitive information such as username, password, and online banking details from its victims. To prevent this, phishing awareness needs to be considered. This research aims to develop a game design framework, which enhances user avoidance behaviour through motivation to protect users from phishing attacks. In order to do this, a theoretical model derived from Technology Thread Avoidance Theory (TTAT) was developed and used in the game design framework (Liang & Xue, 2010). A survey study was undertaken with 150 regular computer users to elicit feedback through a questionnaire. The study findings revealed that perceived threat, safeguard effectiveness, safeguard cost, self-efficacy, perceived severity, and perceived susceptibility elements should be addressed in the game design framework for computer users to avoid phishing attacks. Furthermore, we argue that this game design framework can be used not only for preventing phishing attacks but also for preventing other malicious IT attacks such as viruses, malware, botnets and spyware.
