Fintech, which means the convergence of finance and information technology, becomes a hot topic in the financial sector. Through innovative activities on financial services, ICT(Information and Communication Technology) is integrated into the overall financial industry, and a new form of financial services could be expected to improve the existing financial system. On the other hand, fintech services are relatively vulnerable to security issues. Due to the process simplication and the channel fusion, the leakage of personal and financial informations, authentication bypass, phishing, and pharming are getting more concerned. In this study we investigated the security risk of fintech services in the viewpoints of service provider, technology adoption, and security policy. The possible countermeasures to reduce those risks are suggested because security is an important criterion for selecting financial services. This study basically offers quantification of the potential security risks and step-by-step control measures about business processes in the fintech services. The suggested security model includes user authentication, terminal security, payment information protection, API(Application Programming Interface) security, and abnormal transaction monitoring. This study might contribute to an understanding of the security risks and some possible measures for mitigating those risks on the practical perspective.

The rise in popularity of cloud services has brought about a heightened concern for security in the field of cloud computing. As a response, governments have implemented CSAP(Cloud Security Assurance Program) to ensure the security of these services. However, despite such measures, the emergence of various security vulnerabilities persists, resulting in incidents related to cloud security breaches. To address this, the utilization of Common Vulnerabilities and Exposures (CVE) has been proposed as a means to facilitate the sharing of vulnerability information across different domains. Nevertheless, the unique characteristics of cloud services present challenges in assigning CVE IDs to the diverse range of vulnerabilities within the cloud environment. In this study, we analyzed how CVE can be effectively employed to enhance cloud security. The assignment of a CVE ID is contingent upon the fulfillment of three rules in the Counting Decision and five rules in the Inclusion Decision. Notably, the third rule in the Inclusion Decision, INC3, clashes with the nature of cloud services, resulting in obstacles in assigning CVE IDs to various cloud vulnerabilities. To tackle this issue, we suggest the appointment of designated individuals who would be responsible for overseeing specific areas of cloud services, thereby enabling the issuance of CVE IDs. This proposed approach aims to overcome the challenges associated with the unique characteristics of cloud services and ensure the seamless sharing of vulnerability information. Information sharing regarding vulnerabilities is crucial in the field of security, and by incorporating cloud vulnerabilities into the CVE system, this method can contribute to enhancing the security of cloud services.

The service industry has been acknowledged as a critical part of mobile banking services in recent years. This study examines the impact of e-service quality and loyalty on the intention to use and use behavior of mobile banking services in Mongolia, a Central Asian country. As a result, based on past research, a conceptual model was suggested. This study comprises 209 completed questionnaires from young Mongolians who own a bank account and a smartphone. The data was collected based on convenience sampling, and it was analyzed with SmartPLS software using a partial least squares-structural equation modeling (PLS-SEM) technique. The findings indicate that system quality, interface design, and security assurance have a significant positive impact on service quality; service quality has a positive impact on loyalty. Moreover, the results reveal that service quality and loyalty have a significant influence on the intention to use mobile banking services. The findings of this study suggest that local or international banks and financial institutions in Mongolia should consider system quality, interface design, and security concerns as key successors to building perceived security quality to retain current mobile banking users and attract new customers.

Smart devices refer to various devices and control equipment such as health care devices, imaging devices, motor devices and wearable devices that use wireless network communication (e.g., Wi-fi, Bluetooth, LTE). Commercial services using such devices are found in a wide range of fields, including home networks, health care and medical services, entertainment and toys. Studies on smart devices have also been actively undertaken by academia and industry alike, as the penetration rate of smartphones grew and the technological progress made with the fourth industrial revolution bring about great convenience for users. While services offered through smart devices come with convenience, there is also various security threats that can lead to financial loss or even a loss of life in the case of terrorist attacks. As attacks that are committed through smart devices tend to pick up where attacks based on wireless internet left off, more research is needed on related security topics. As such, this paper seeks to design an access control method for reinforced security for smart devices. After registering and authenticating the smart device from the user's smart phone and service provider, a safe communication protocol is designed. Then to secure the integrity and confidentiality of the communication data, a management process such as for device renewal or cancellation is designed. Safety and security of the existing systems against attacks are also evaluated. In doing so, an improved efficiency by approximately 44% compared to the encryption processing speed of the existing system was verified.
