1. Introduction
Smart cities are emerging as an innovative solution to the challenges urban areas face in the 21st century. They integrate digital technology, data, and connectivity to improve the quality of life for citizens and foster sustainable development [
1]. In recent years, various countries have strongly committed to implementing smart city initiatives, with ambitious projects to create intelligent urban environments [
2]. Developing smart cities is becoming a top priority as these countries strive to diversify their economies and reduce dependency on traditional industries. However, implementing these innovative urban environments raises critical concerns related to cybersecurity, given the increased connectivity and reliance on digital infrastructure [
3]. As the potential for future possibilities attracts people from various parts of the country and the world, the rapid population growth in these smart cities has highlighted significant security concerns and increased the informal economy [
4]. Ensuring the safety and security of citizens, infrastructure, and data in smart cities remains a pressing issue that needs to be addressed to fully realize the potential benefits of these innovative urban environments.
Similarly, the smart cities in Saudi Arabia faced the same challenges. They reflected a 689% rise in residents compared to a 146% rise globally over the previous 56 years [
5]. Identification of criminal activities, technological innovation, an excellent educational system, modern hospitals, and other social services are all required because of Saudi Arabia’s growing population [
6]. Smart facilities, networks, smart waste management framework, and smart management systems are all required because of Saudi Arabia’s growing population. Technology today, such as cybersecurity systems, supports real-time data collection, recognizes, and analyzes possible issues to efficiently accomplish assets and resources [
6]. In addition, Mohammad and Abdulqader [
7] conducted a study of finding cybersecurity requirements in Saudi smart cities. They concluded that significant concerns include privacy, data security, and preventative measures. The proposed solutions in the research may be sufficient on their own, but it needs to be clarified what would occur if all of these solutions were combined into a single comprehensive system.
Smart cities worldwide, including those in development, still need to universally establish comprehensive action plans that detail their strategies to respond to potential cyberattacks targeting their facilities, infrastructure, and information and communication technology systems. Weaknesses in any one component can have far-reaching implications due to the inherent interconnectedness of all processes. As a result, recommendations should be made available to the organizations responsible for selecting and vetting the technologies that will be utilized in smart cities globally. As smart cities continue to grow and integrate advanced digital technologies, they become increasingly susceptible to cyber threats [
8]. Cybersecurity is a crucial aspect of smart city development, as it aims to protect information, communication systems, and critical infrastructure from unauthorized access and attacks [
9]. Despite the growing importance of cybersecurity, more research is needed on the cultural, social, and economic challenges and issues in adopting cybersecurity practices in smart cities worldwide [
10]. Addressing these challenges and prioritizing cybersecurity will be essential to ensuring the safety and resilience of smart cities as they become more prevalent.
Therefore, this study seeks to address this knowledge gap by examining the challenges and issues that hinder the effective implementation of cybersecurity practices in the context of smart Saudi cities. Therefore, as smart cities continue to gain traction in Saudi Arabia, understanding the challenges and issues related to adopting cybersecurity practices becomes vital to ensuring the successful development and operation of these urban environments [
10]. Additionally, analyzing the cultural, social, and economic factors that influence the implementation of cybersecurity measures can provide valuable insights into the unique context of Saudi Arabia, which can be used to develop targeted strategies and policies for improving cybersecurity in its smart cities [
11]. Finally, the study offers the following research objectives:
- 1
To identify the challenges and issues in adopting cybersecurity and safety practices by IT professionals and the common public in smart Saudi cities.
- 2
To explore the economic, social, and cultural factors/challenges that make the cybersecurity framework practicable in smart Saudi cities.
- 3
To conceptualize a cybersecurity-based UTAUT3 model in smart Saudi cities.
5. Conceptualization of the Cybersecurity-Based UTAUT Model
After identifying the challenges and gaps in the survey, it is shown that other economic, cultural, and social factors are related to behavioral intention and actual use of behavior. The literature review showed that economic, cultural, and social factors significantly contribute to behavioral intention and the actual behavior of using smart city technologies. The study identified several factors from the literature studies and tested the results. The factors for each antecedent are termed economic factors, i.e., privacy design (safety), cyber threat intelligence and analysis platform (resiliency); social factors, i.e., digital trust (confidentiality), cyber responses and resilience (availability); and cultural factors, i.e., cyber competencies and awareness program (integrity).
The study used the unified theory of acceptance and use of technology (UTAUT) as the basis to develop a cybersecurity-based UTAUT3 model in smart Saudi cities. Popova and Zagulova [
27] in the smart city of Riga, Latvia, use UTAUT models in predicting cybersecurity behaviors and intentions, such as in a study. The study findings showed that all factors of the UTAUT model (i.e., performance expectancy, effort expectancy, social influence, and facilitating conditions) significantly contributed to the behavioral intention and actual use of behavior in adopting smart city technologies. However, they claimed that UTAUT factors might not predict adopting smart city technologies due to the underdeveloped culture. Kuberkar and Singhal [
28] conducted a study by testing the behaviors of passengers toward smart city transport technologies. The study stated that performance expectancy, effort expectancy, social influence, facilitating conditions, trust, and anthropomorphism affect behavioral intention and actual use of behavior in adopting smart city transport technologies. Meanwhile, Van Zoonen [
29] recognized security and privacy as contributing factors in the smart city awareness campaign model, in which privacy and security variables are connected to applying the appropriate realm of the smart city.
In this context, some of the issues include developing resilience in information security; increasing awareness of privacy risks; growing the security and integrity of online content, thereby encouraging greater use of information systems [
30]; generating policy standards for cybersecurity based on global best practice; constructing resilient information systems; and increasing concern regarding security risks [
17]. Alzahrani [
31] conducted a study claiming that cybersecurity’s availability, confidentiality, and integrity are linked to cybersecurity trust and culture. It is helpful to increase the safety of critical systems and cyber resilience capability, conduct research and training, and market cybersecurity remedies, products, or services when government organizations and commercial sectors engage. Therefore, Alzahrani [
31] stated that data availability, confidentiality, and integrity should be enhanced to cover the lack of system development and IT experts. On the other hand, Alhalafi and Veeraraghavan [
32] proposed recommendations for Saudi Arabia to implement a cybersecurity framework for smart cities. They claimed that smart cities require a model of cybersecurity that will safeguard their integrity and guide the reaction to possible assaults and hazards [
32]. Based on the study’s findings and evidence in the literature, the study develops a cybersecurity-based UTAUT3 model in smart Saudi cities (see
Figure 2):
8. Discussion and Conclusions
The existing literature and studies underscore the significant influence of economic, cultural, and social factors on the behavioral intention and actual use of smart city technologies. Applying the unified theory of acceptance and use of technology (UTAUT) to cybersecurity contexts, particularly in smart cities, has yielded significant findings concerning performance expectancy, effort expectancy, social influence, and facilitating conditions. However, gaps in cultural development and specific factors such as privacy, security, trust, and anthropomorphism were also identified as critical aspects of technology adoption. Emphasizing the need for resilient information systems and raising awareness of privacy and security risks are pivotal steps toward strengthening smart city infrastructure. Therefore, factors including data availability, confidentiality, and integrity are addressed to mitigate the dearth of system development and IT expertise. Consequently, developing and implementing a comprehensive cybersecurity framework is paramount to safeguarding the integrity of smart cities, providing guidance for respoding to potential threats, and promoting a robust and secure digital environment. After that, this study examines the widespread phenomenon of testing the behavioral intentions in adopting cybersecurity awareness programs in two cities in Saudi Arabia (i.e., Riyadh and Neom). The study conducted two surveys. The first survey was carried out to explore the challenges and issues in adopting cybersecurity practices in smart Saudi cities. The second survey was carried out to develop and validate the conceptual cybersecurity-based UTAUT3 model. In the first phase, the study targeted 554 respondents (common public). In the second phase, the study targeted 108 IT professionals because they provided the most authentic responses to validate a new model in smart Saudi cities. The survey results reveal several key insights about trust in cyberinfrastructure and the digital economy in Saudi Arabia. First, there is a widespread perception of weak cybersecurity platforms and a need for more confidence in the country’s ability to design and deploy smart cities. Second, respondents are highly aware of various IT issues and have experienced security or privacy breaches. Third, Saudi citizens understand the importance of cyber threats and express a strong interest in participating in cybersecurity awareness programs. Furthermore, most respondents believe that advancements in IT infrastructure and social apps, notably Snapchat and Twitter, have the potential to impact Saudi culture. However, a considerable portion of respondents remains neutral on this issue. While technical abilities such as deep-packet inspections are limited among the respondents, there is optimism that public and governmental agencies can match the private sector shortly.
The study results emphasize the importance of economic, cultural, and social factors in shaping behavioral intention and actual use of smart city technologies. Key factors identified include privacy design, cyber threat intelligence, digital trust, cyber responses, resilience, and cyber competencies and awareness programs. Moreover, the R2 values of 0.567 and 0.537 for behavioral intention and user behavior, respectively, indicate that the nine factors (performance expectancy, effort expectancy, social influence, facilitating conditions, safety, resiliency, confidentiality, availability, and integrity of cybersecurity) in the cybersecurity-based UTAUT3 model explain a significant proportion of the variance in these two dependent variables. This suggests that a comprehensive approach addressing economic, social, and cultural factors is crucial for increasing trust in cyberinfrastructure and promoting the adoption of cybersecurity measures in smart cities within Saudi Arabia.
Combining the two surveys’ findings, the study concludes by emphasizing the interconnectedness of public perception, technical abilities, and the role of economic, social, and cultural factors in influencing the adoption of cybersecurity measures in Saudi Arabia’s transition to a digital economy and smart cities. Additionally, the results highlight the need for effective government policies, incentives, and awareness programs to enhance the overall trust and confidence in the country’s cyber infrastructure and digital advancements. The findings of the study presented cybersecurity aspects and factors, including the actual use of behavior, availability, behavioral intention, confidentiality, effort expectancy, facilitating conditions, integrity, performance expectancy, resiliency, safety, and social influence in the context of smart cities. These were each measured with several items, which resulted in factor loadings ranging from 0.746 to 0.888, indicating a high level of validity and reliability. Moreover, all constructs scored above 0.6 in average variance extracted (AVE), implying good convergent validity. Furthermore, all constructs’ Cronbach alpha and composite reliability values were above the acceptable 0.7 thresholds, indicating high reliability and internal consistency. The correlation matrix noted that all the constructs were significantly correlated with each other, ranging from 0.317 to 0.733, with the diagonal showing the square root of AVE, illustrating adequate discriminant validity. This indicates that the constructs are related yet distinct from each other, thereby supporting the validity and reliability of the scales used in measuring these constructs. These measurements could be instrumental in shaping cybersecurity policy and best practices in the context of smart cities.

This will encourage greater collaboration in developing and maintaining cybersecurity practices, ultimately leading to more secure and resilient smart cities.
Preserving cultural values: The UTAUT3 model considers the potential impact of IT infrastructure advancements on Saudi culture. By considering these cultural factors, policymakers and city planners can ensure that cybersecurity practices align with societal values and contribute positively to the overall development of smart cities.
8.2. Limitations and Future Directions
While the study provides valuable insights into the factors influencing cybersecurity practices in smart Saudi cities, it has some limitations. The sample size and demographic distribution of respondents may only represent part of the population, potentially limiting the generalizability of the findings. The most significant limitation of the study is that it developed and validated the cybersecurity-based UTAUT3 model but did not examine the effect of all nine factors on behavioral intentions and actual use of behavior in adopting cybersecurity practices; a future study should consider this aspect to investigate the impacts. Furthermore, the study focuses solely on Saudi Arabia, and the results may not directly apply to other countries or regions with different cultural, economic, and social contexts. Future research could address these limitations by employing more extensive and diverse samples and conducting comparative studies across multiple regions or countries. Additionally, researchers could explore the long-term effects of implementing the UTAUT3 model on the overall security and resilience of smart cities, examine the role of emerging technologies such as artificial intelligence and blockchain in enhancing cybersecurity, and investigate the impact of evolving cyber threats on user behavior and adoption patterns.
