Abstract
This research delves into the cybersecurity vulnerabilities of construction sites in Abuja, Nigeria, within the context of Construction 4.0 advancements. Recognizing the growing risk of cyber threats in the industry, the research explores the critical intersection of emerging technologies and effective cybersecurity practices. The central tenet of the research is the urgent need for robust cybersecurity measures in light of the construction sector's inherent susceptibility to cyberattacks. Employing a mixed-methods approach, including semi-structured interviews to guide the development of surveys conducted with 323 participants carefully selected using stratified sampling, the research comprehensively analyzes the current state of cybersecurity practices within Abuja's construction landscape. Key findings reveal intricate dynamics of cybersecurity preparedness across different industry segments. Notably, 0% of the surveyed participants reported dedicated cybersecurity teams and minimal training on vulnerabilities was conducted. The analysis identifies a lack of correlation between years of experience and digital adoption with the implementation of cybersecurity best practices. Underscoring the crucial role of cybersecurity in Construction 4.0 initiatives, the research emphasizes the need for tailored strategies and policies specific to the Nigerian context. Recommendations advocate for collaborative efforts, enhanced knowledge-sharing, and strategic investments to fortify the sector against evolving cyber threats.
