'05. June, the first Internet banking accident occurred by the malignant cord. It discontinued security programs for protecting important financial informations. A computer hacker had made a collation of password, OTP(One Time Password) values etc and illegally withdraw one´s savings from the bank using the financial information. The attackers are continuously attempted with the hacking tool under bypass security programs as the vaccine program or the personal fire-wall. Therefore, an electronic financial system should be composed with the goal which is to protect financial informations from user's terminal to a banking server. In this paper, we make an analysis of menaces in electronic financial transactions and explain considerable security issues to enhance safety in Internet banking, CD/ATM and mobile banking.

Most researches on the corporate credit rating are generally classified into the area of bankruptcy prediction and bond rating. The studies on bankruptcy prediction have focused on improving the performance in binary classification problem, since the criterion variable is categorical, bankrupt or non-bankrupt. The other studies on bond rating have predicted the credit ratings, which was already evaluated by bond rating experts. The financial institute, however, should perform effective loan evaluation and risk management by employing the corporate credit rating model, which is able to determine the credit of corporations. Therefore, in this study we present a medium sized corporate credit rating system by using Artificial Neural Network(ANN) and Analytical Hierarchy Process(AHP). Also, we developed AHP model for credit rating using non-financial information. For the purpose of completed credit rating model, we integrated the ANN and AHP model using both financial information and non-financial information. Finally, the credit ratings of each firm are assigned by the proposed method.

This study thus set out to empirically analyze connections between the success factors of marketing and management performance in the silver industry. For that purpose, the investigator analyzed relations between independent variables, which include such success factors of marketing as market segmentation, product mix, customer relational management, brand asset, price strategy, and marketing information system, and dependent ones, which include financial and non-financial management performance. Those results partially support the hypothesis that the six success factors of marketing set in the study have effects on financial and non-financial management performance in the silver industry. Customer relational management had the biggest influence, being followed by brand asset and price strategy in the order. Those results indicate that companies need to consider customer relational management, brand asset, and price strategy before other success factors of marketing to achieve financial and non-financial management performance in the silver industry.

As measures for protecting users and ensuring security of electronic financial transactions, such as online banking, financial institutions in South Korea have implemented network segregation policies. However, a revision of such domain-centered standardized network segregation policies has been increasingly requested because of: 1) increased demand for remote work due to changes resulting from COVID-19 pandemic; and 2) the difficulty of applying new technologies of fintech companies based on information and communications technologies (ICTs) such as cloud services. Therefore, in this study, problems of the remote work environment arising from the network segregation policy currently applied to the financial sector in South Korea and those from the application of new ICTs such as fintech technology have been investigated. In addition, internal network protection policies of foreign financial sectors, such as those of the United States, United Kingdom, European Union, and Russia, and internal network protection policies of non-financial sectors, such as control systems, have been analyzed. As measures for the effective improvement of the current network segregation policy, we propose a policy change from domain-based to data-centric network segregation. Furthermore, to resolve threats of hacking at remote work, recently emerging as a global problem due to COVID-19 pandemic, a standard model for remote work system development applicable to financial companies and a reinforced terminal security model are presented, and an alternative control method applicable when network segregation is not applied is proposed.

One of the hottest issues of security is information leakage of financial institution. Financial institutions including commercial banks are frequently threatened by attempts of leakage through hacking and vulnerability, and this information is centered on personal information of their clients. Through this study, I found out that security managers of financial institutions are trying to prevent the leaking of private information, but in fact most of them barely know where their personal information is. Even if they know where it is and trace the data, it is often found in unexpected places. Because there is a lot of waste in time and human resources as search is done manually, we have understood that responding to IT Compliance requires a lot of effort. This study is to improve IT Compliance response and protect information leakage through monitoring PC and servers, the main storage of personal information by automated system, periodically.

The rapid changes of financial environment have increased the need and demand for personal financial advisory service from financial experts. In particular, as the individual customers want to get more customized financial services, the financial institutions created the private banking (PB) sector and have constantly expanded their PB services. However, it remains still problematic that the private banking system requires high costs so that the number of eligible customers who can have proper PB services is quite limited. To solve this problem, we propose an intelligent agent that can provides specialized and customized personal financial advisory services to the customers with low costs. The proposed agent systemizes and structures the information and knowledge of financial experts in private banking services so that individual customers can easily access to high-quality PB services when they need. On the first attempt we develop a framework of U-smart PB, an intelligent agent for personal financial management based on different scenarios related to personal financial decisions, and derive its core services. This system not only provides information simply, but also proposes to support personal investment decisions technically as an intelligent agent that embodies real-time customized financial management in a ubiquitous environment, regardless of time and place.

The methods of electronic financial fraud continue to evolve. Various research and countermeasures have been proposed to counter this problem, but it is difficult to eradicate it. The purpose of this study is to analyze the risk of electronic financial fraud through MS Threat Risk Modeling and to propose the countermeasures against the electronic financial fraud. As a result of the analysis, it is confirmed that despite the difference of authentication methods, there is a high risk of pharming, and it is difficult to prevent attack by using only additional authentication means, device security or user authentication based security system. Therefore, this study suggests the introduction of preventive measures such as readjustment of transaction limit by security means, account authentication, and additional physical security measures. It also suggests the establishment and implementation of a comprehensive electronic financial fraud prevention policy through linkage of electronic fraud prevention system and improvement of public relations and user awareness.

The Management Discussion and Analysis(MD&A) provides investors with an opportunity to gain insight into the company from a manager's perspective and enables short-term and long-term analysis of the business. And MD&A is an important channel through which companies and investors can communicate, providing a useful source of information for analyzing financialstatements. MD&A is measured by the quality of disclosure and there are many previous studies on the usefulness of disclosure information. Therefore, it is very important for the financial analyst who is the representative information user group in the capital market that MD&A Disclosure Quality is measured in real-time in combination with IT information technology and provided timely to financial analyst. In this study, we propose a method that real-time data is converted to digitalized data by combining MD&A disclosure with IT information technology and provided to financial analyst's information environment in real-time. The real-time information provided by MD&A can help the financial analysts' activities and reduce information asymmetry.
