The human factor plays a key role in cybersecurity, particularly in susceptibility to social engineering. We conducted a systematic review with quantitative and qualitative analyses to explore this relationship, examining how sociodemographic factors, such as age, gender, education, professional sector, and culture, influence cybersecurity awareness and behavior. Our results highlight clear correlations: higher education correlates with better practices, and notable differences emerge across all groups. These disparities are interpreted through the lens of social theories, leading to the initial proposal of a framework for personalized cybersecurity training that leverages accessible sociodemographic data to enhance awareness and resilience.
