The exponential growth and the interconnected nature of digital technologies, the domains of human dimension and the cybersecurity plays a critical role in ensuring aviation safety. In cybersecurity, human factors such as user awareness, social engineering vulnerabilities, insider threats, and organizational security culture significantly influence the effectiveness of defense mechanisms. Particularly the factors of Cybersecurity Awareness (CSA), Negligence (N), Computer Literacy (CL), Emotional Stability (ES) would influence the Response Behavior which has found that a positive correlation with the Cybersecurity Index. This paper is developed from a positivist philosophy, treating the use of statistical, experimental and other numerical data, to describe the actions and phenomena observed, and the correlations and interactions between them. It is also used the deductive approach to test the theory and correlations of variables through a hypothesis. Target population of this study was stakeholders of the aviation industry and sample was scientifically drawn using proportionate stratified random sampling technique. Tool to measure variables was online questionnaire posted on Google Forms. Internal consistency reliability test was satisfied with fairly high value of Cronbach’s Alpha and sample adequacy was strengthen by KMO and Bartlett's Test with higher value of KMO.  Human errors, whether in digital behavior or operational judgment, can compromise both domains, highlighting the need for integrated, human-centric training and design. This paper has developed an index to support the implementation strategy to mitigate the vulnerabilities through cross-disciplinary approaches, continuous education, and culture development to build resilient systems that safeguard both digital and physical aspects of aviation operations.
