# Information Security Applications in Smart Cities: A Bibliometric Analysis of Emerging Research
## 1 Introduction  
The advancement of solutions and tools focused on information security for smart cities is gaining prominence worldwide [1; 2; 3; 4; 5; 6; 7]. Furthermore, there has been a noticeable increase in the production of large volumes of data, agility in information exchange, data analysis (Data Science), development of smart cities, and connectivity between various devices. These continuous interactions with internet-focused solutions (Internet of Things--IoT) must be conducted in compliance with regulations [8; 9; 10]. However, they concurrently introduce profound challenges, especially in terms of data governance, and there is a growing emphasis on safeguarding the integrity, confidentiality, and availability of data as it is generated, processed, and exchanged across diverse entities, spanning from private organizations to public sectors and the general populace [11; 12; 13; 14]. As public services gravitate towards interconnected digital ecosystems, we can identify significant potential benefits, such as streamlined operations and bolstered resilience incritical infrastructures. Nonetheless, for metropolises and regions striving to transition into the smart city paradigm, it is imperative to not only meticulously assess but also proactively mitigate the inherent cybersecurity risks stemming from such integration [13; 14; 15; 16; 17; 18; 19; 20; 21]. While no technology solution can guarantee complete security, communities need to implement smart city technologies while considering the need to balance efficiency, innovation, and cybersecurity [20; 22; 23; 24; 25]. This context demands promoting privacy protections, national security, and the secure operation of infrastructure systems. Cities should tailor best practices to their specific cybersecurity requirements, ensuring the protection of citizens' private data as well as the security of sensitive government and business information [20; 24; 26; 27]. By promoting protection through proper guidelines, communities can strive to create a safe and secure environment while embracing the benefits of technological advancements [28]. In recent years, organizations have turned their attention to the increased risks that the lack of information security causes in the evolution and survival of businesses, mainly due to the large offer of technological devices and the growing access and dissemination of data and information [29; 30; 31; 32]. The lack of information security evidence many losses for the different business stakeholders, especially when it negatively impacts the trust of customers and suppliers, the efficiency of services, the availability of operations, the credibility of the business, and the image of the company [33]. In this sense, organizations have adopted strategies to prevent the occurrence of security flaws caused by Denial of Service Attacks (DoS), hacking, malware, phishing, spoofing, ransomware, spamming, and other types of cyberattacks [34; 35; 36; 37; 31]. Strategies, in general, are adopted to protect the business performance and maintain operational efficiency at competitive levels [38]. Thus, excellence in the cybersecurity process is essential to ensure the integrity, availability, and confidentiality of business data and information [39; 40]. The discussion over the importance of information security has been highlighted in recent literature. The advancement of research in the area has considered aspects from risk assessment to recovery and resilience of cybersecurity [41; 42]. On many occasions, Information Technology (IT) managers seek to analyze solutions to conduct operational strategies aimed at protecting business [43]. In recent years, although many researchers [44; 45; 46; 47; 48; 49] have presented approaches to the importance, investment, and contribution of cybersecurity to organizations, society, and government, there is still a gap in the current literature: there are no studies that analyze the most influential works in the area of cybersecurity with an integrated view.
