Cybersecurity technologies offer secure channels to enable the confidentiality, integrity, and availability of data and services. Human factors; e.g. demographics, personality traits, and human values, which are linked with greater cybersecurity vulnerabilities, have drawn less attention. It is important to understand how to increase ethical awareness for cybersecurity professionals via training. This ethical awareness helps professionals make better moral judgments prior to final decisions and reduces the risk of unexpected human implications. To sensitise players to five cybersecurity ethical principles (beneficence, non-maleficence, justice, autonomy, and explicability), we created a serious game. This game allows players to explore multiple cybersecurity scenarios based on these five cybersecurity ethical principles. Although the analysis does not support the claim that the game increased ethical awareness in general, it did help promote better ethical understanding in some cases where players advanced from providing non-ethical to ethical justifications in a cybersecurity scenario after playing the game.
