인터넷 뱅킹 서비스가 보편화되면서 많은 사용자들이 온라인을 통한 재화의 교환이 가능하였다. 하지만 이러한 이점에도 불구하고 인터넷 뱅킹 서비스에서 존재하는 보안위협에 의하여 사고사례가 지속적으로 발생하는 실정이다. 이러한 문제점을 보완하기 위하여 인터넷 뱅킹 서비스의 전 구간에 걸쳐 다양한 보안기술이 적용되었으며, 본 논문에서는 금융기관 구간과 네트워크 구간에 적용된 보안기술에 대한 조사 결과를 서술한다. 본 논문의 결과를 통하여 내부자에 의하여 발생하는 피해사례와 구현과정에서의 취약점으로 인하여 발생하는 위협에 대응하기 위한 참고 자료로써 활용 가치가 있을 것으로 사료된다.

Joint financial network of Korea Financial Telecommunications and Clearings Institute, which is an essential facility with a natural monopoly, maintained its closedness as monopoly/public utility model, but it has evolved in the form of open banking in order to obtain domestic fintech competitiveness in the rapidly changing digital financial ecosystem such as the acceleration of Big Blur. In accordance with digital transformation strategy of financial institutions, various ICT companies are actively participating in the financial industries, which has been exclusive to banks, through the link technology called Open API. For this reason, there has been a significant change in the financial service supply chain in which ICT companies participate as users. The level of security in the financial service supply chain is determined based on the weakest part of the individual components according to the law of minimum. In addition, there is a perceived risk of personal information and financial information leakage among the main factors that affect users' intention to accept services, and appropriate protective measures against perceived security risks can be a catalyst, which increases the acceptance of open banking. Therefore, this is a study on factors affecting the introduction of open banking to achieve financial innovation by developing an open banking security control model for financial institutions, as a protective measures to user organizations, from the perspectives of cyber financial security and customer information protection, respectively, and surveying financial security experts. It is expected, from this study, that effective information protection measures will be derived to protect the rights and interests of financial customers and will help promote open banking.

Theoretically, both of fund transfer and balance inquiry which are typical Internet banking services are influenced by the beliefs on the use of Internet banking such as perceived risk and convenience, which have been shown as in the other studies. However, the use of fund transfer can be more sensitive than that of balance inquiry by the beliefs on Internet banking use since the former is not only more risk involved but also more complicated in using than the latter. The objective of this study is to analyze the relationship between the use of two Internet banking services-fund transfer and balance inquiry-and the beliefs on Internet banking use-security risk, convenience and social Influence. For this purpose, we provide the research model for explaining the difference between balance inquiry and fund transfer in the degree of influencing by security risk, convenience and social influence and test it empirically by collecting data from surveying for 206 internet banking users. In result, we show validity of the suggested model by Partial Least Square(PLS) approach.

본 논문은 인터넷 뱅킹 서비스의 안전성을 평가하기 위한 보안위협을 분류하고 보안 요구사항을 제안하는데 그 목적이 있다. 분류한 보안위협은 기존에 발생하였던, 그리고 발생이 가능한 보안위협을 기반으로 분석하였으며, 이를 통하여 보안 요구사항을 제안하기 위한 기반을 다질 것으로 사료된다. 보안위협 도출을 위하여 인터넷 뱅킹 서비스의 구조를 금융기관 구간과 네트워크 구간, 사용자 구간으로 분류하였으며, 각 구간에서 발생하는 보안위협을 도출하였다. 특히, 사용자 구간이 상대적으로 취약하기 때문에 전체 서비스의 안전성을 확보하기 어려운 상황이므로 이를 중점적으로 분석하였다. 분석한 보안위협을 토대로 안전한 인터넷 뱅킹 서비스를 구성할 수 있을 것으로 예상된다.

Although, recently, studies on Internet banking users' behavior have been frequently found in some academic journals, most of them have ignored security anxiety which may be considered as important factors influencing usages of Internet banking. We propose an research model for Internet banking users which is an extended version of the Technology Acceptance Model(TAM) by adding new variable, security anxiety. For empirical support of our model, we survey for 298 samples and analyze it by structured equation model(SEM). In result, our proposed model is proved as a valid one in which all hypotheses except one are accepted and the values of model fitness are relatively high.

In this paper, we investigated the factors affecting the intention to use smartphone banking with a research model based on the Technology Acceptance Model (TAM) extended to include security risk, trust, and self-efficacy. With analysis after controlling factors such as age, gender, and previous experience of smartphone banking that may have effects, we conclude that perceived usefulness, perceived ease of use, security risk, and trust have direct effect on the intention to use smartphone banking, and self-efficacy has indirect effect on the intention to use through mediation of perceived ease of use. We performed a study to check the validity of TAM in the context of smartphone banking, and confirmed that perceived ease of use has both direct and indirect effect on the intention to use.

Risk has been considered as one of very important topics in traditional consumer behavior theoretically and practically since its tendency of minimizing errors rather than maximizing utilization in addition to its intuitive appealing with very high explaining power. In addition to a traditional view of risk, importance of risk in online transactions such as Internet banking is due to technical instability in security of the Internet as well as temporal and spatial separation of transaction partners. Therefore, risk in online transactions should be analyzed by a very comprehensive way since it is very inherent in the Internet. The objective of this study is to suggest a research model for explaining the use of online transactions in some risk related variables including risk results, security result, perceived security, and social influence and show its validity by applying it to Internet banking users. In result, hypotheses suggested by our research model are shown to be valid ones.

최근 우리나라를 비롯한 EU, 영국 등은 금융구조 개혁 및 금융소비자의 편의성 제고를 위하여 금융회사가 보유하고 있는 금융정보를 핀테크기업에게 개방하는 오픈뱅킹을 적극 추진하고 있다. 향후 오픈뱅킹이 점차 활성화될수록 오픈뱅킹 제공기관의 안정성 확보 및 이용자 보호의 중요성은 더욱 커질 것이다. 특히 우리나라는 전자금융거래의 안정성과 신뢰성 확보를 위하여 2007년부터 시행해 온 전자금융거래법이 있지만, 오픈뱅킹 제공기관에게 적용하기 어려운 한계가 있어 오픈뱅킹에 대한 보안사고 예방 및 이용자 보호가 취약해질 위험성이 있다. 따라서 본 논문에서는 오픈뱅킹에 관한 외국의 규제를 살펴보고, 국내 오픈뱅킹의 안정성 강화 및 이용자 보호를 위한 규제 개선 방안을 제시해 본다.

금융회사가 전자금융 서비스를 제공하기 시작하면서 전자금융 서비스는 다양화 되었고 전자금융 사용은 지속적으로 증가하고 있다. 이에 금융회사는 안전한 전자금융서비스를 제공하기 위하여 금융 보안정책을 적용하고 있으나 전자금융 사고는 계속해서 지능화되고 증가하고 있는 상황이다. 금융감독기관은 최근 인터넷 전문은행 등장과 핀테크 활성화와 더불어 비대면 실명확인 제도 신설 및 전자금융 거래를 통한 자금이체 시 공인인증서 또는 일회용비밀번호 의무사용 폐지 등의 규정을 개선하여 이용자의 편리함을 추구하는 동시에 금융회사에게는 이상금융거래 탐지 시스템 고도화 및 개선을 통한 불법이체 사고 방지를 권고하고 있다. 본 논문에서는 금융회사 제반 상황에 적합한 블랙리스트기반 자동화 탐지 기법을 제안하고 블랙리스트 정보를 레벨링하여 보안레벨에 따른 블랙리스트기반과 통계모델을 연동한 실시간 이상금융거래 탐지 기법을 제안하며, 기존 전자금융 사고유형 분석을 통한 특징적 패턴에 따른 실시간 이상금융거래 탐지기법의 대응 모델을 제안하고자 한다.
