The objective of this study is to examine the relationship between the quality of cybersecurity awareness programme, leadership support, cybersecurity culture and employee engagement with employee accountability at Bank XYZ. The study population comprises 16,500 employees. For the sample, 170 questionnaires were distributed and 158 returned; of which 150 were found valid and included for data processing. This is a quantitative study using Likert Scale questionnaire instrument. Data are analysed using Partial Least Squares Structural Equation Modelling (PLS-SEM). The result shows that the quality of the cybersecurity awareness program has a positive and significant impact on employee engagement (β = 0.195; p = 0.014) and employee accountability (β = 0.206; p = 0.010). Employee engagement has a positive and significant impact on employee accountability (β = 0.222; p = 0.008) and partially mediates the effect of program quality on accountability (β = 0.043; p = 0.046). Leadership support has a positive and significant impact on cybersecurity culture (β = 0.566; p < 0.001). Cybersecurity culture has a positive and significant impact on employee engagement (β = 0.265; p = 0.001) and does not have a significant impact on employee accountability (β = 0.092; p = 0.257). The study results show that the quality of the cybersecurity awareness programme influences employee accountability directly and indirectly (through employee engagement), leadership support has a significant effect on the cybersecurity culture.
