Seeing the actual condition of cyber terror that is happening these days, a situation on cyber security is being emerged as serious social issue beyond damage of an individual or enterprise. Above all, it is a situation of being difficult to guess damage, which may occur due to the leakage of personal information or to the leakage of secret information in enterprise or institution. To prevent this hacking damage, a system or solution is being developed diversely. However, it is difficult to perform security in the perfect form. The real situation is that requires the technology available for perceiving hacking incident in advance ahead of this, as well as the technology of detecting and coping with hacking incident in the shortest time in the aspect of range or scale in damage, which is created by hacking incident. The purpose of this study is to suggest solution on the whole defense of system through network by grasping the whole situation on this cyber terror. For the objective dubbed the internal data loss prevention, the mechanism is needed that can preferentially analyze and monitor suspicious behavior and also that can closely analyze data of being doubtful about malicious link. The aim is to propose mechanism available for preparing for potential attack by expanding the subjects of this analysis even into the internal network and separately-divided network without setting limits to the external network.

Financial information systems operated by financial institutions are based on various customers’ information. If leaked for illegal and vicious purposes, financial information can bring a lot of damages, including financial damages. Therefore, continuous demands on IT compliance related to financial information systems have risen as financial policy institutions suggest integrated plans for improvement on clarity of financial information service and reinforcement on safety of information systems operation. In order to meet such demands, financial institutions invested efforts and capital to prevent illegal leaks of financial information outside of barriers, however, it happens that not only do information leaks caused by external factors, but also ones caused by internal information system users occur quite frequently. Therefore, financial information systems must be operated and managed by authorized internal users. For that, this study analyzes various authentication technologies and compliances as advanced research then suggests a new authentication model for financial information system users. Through this model, we expect that the system will be able to secure safety in operation and management of financial information system hence, to deal with illegal leaks of financial information.

내부 정보 유출 사고의 빈도가 높아지게 되면서 이러한 내부 정보 유출을 막기 위해 DLP(Data Loss Prevention), DRM(Digital Rights Management), DB 접근 통제 솔루션, 인터넷 접근 차단 솔루션과 같은 여러 가지 보안 솔루션을 적용하고 있으나, 내부 정보 유출을 시도하는 개인의 행동을 기반으로 개인을 탐지한다는 문제점을 가지고 있다. 본 논문에서는 개인이 아닌 조직으로 이루어진 내부 정보 유출의 행위를 탐지하고 대응하기 위해 보안로그를 위험 사용자들끼리 그룹화 하여 내부 정보 유출 여부를 판단하는 시스템을 제안한다.

이 연구의 의도는 호텔경영정보시스템의 EDP내부통제수준을 일반통제와 응용통제로 구분하여 EDP내부통제가 사용자 만족에 미치는 영향을 실증적으로 접근하는데 두었다. 유효표본 583가 AMOS의 분석에 이용되었으며 밝혀진 결과는 다음과 같다. 첫째, 호텔정보시스템의 EDP내부통제에 일반통제와 응용통제 모두 유의하게 분석되었으며 응용통제가 일반통제보다 더 큰 정의 영향을 미치는 것으로 나타났다. 둘째, 호텔정보시스템의 EDP내부통제와 사용자만족에 유의하지 않는 것으로 분석되었는데, 이는 응용통제와 사용자만족 간의 관계가 유의하지 않은 것으로 나타난데 원인이 있는 것으로 판단된다.

The purpose of this study is to understand the critical role of the hotel information system's EDP(electronic data processing) internal control in the hotel industry. This paper examines the relationships of the hotel information system's internal(general & application) control and user satisfactions. The model was tested using Lisrel analysis on a sample of 583 respondents who have worked with the hotel information system in a hotel environment. The major results of this study are as follows: First, general control and application control have statistically significant influences on EDP internal control. Second, EDP internal control does not have a statistically significant influence on user satisfaction. Consequently we should maximize the user satisfaction of the hotel information system and maximize the value of the hotel business for the benefit of the entire industry.

The purpose of this study is to understand the critical role of the hotel information system`s EDP(electronic data processing) internal control in the hotel industry. This study examines the relationships of the hotel information system`s internal control with that of user satisfactions. This study sets out the research model of influencing factors and the performance of the hotel information system through theoretical studies based on Management Information Systems, and then empirically tests hypotheses related to the model. The model was tested by multiple regression analysis using SPSS10.0 and SEM(structural equation modeling) using Amos4.01 on a sample of 583 respondents who have worked with the hotel information system in a hotel environment. The major results of this study are as follows: First, general control and application control have statistically significant influences on EDP internal control. Second, EDP internal control does not have a statistically significant influences on user satisfaction. The study`s findings also indicate that Kim Eung-Jun`s model is not consistent with the results of this project. Based on the results of the study, EDP internal control indirectly effects on user satisfactions. Consequently, the more investment in EDP internal control and hotel information system the greater the user satisfaction of the hotel information system. Third, the EDP internal control and the hotel information system`s quality should be considered simultaneously to maintain the competitive powers in the struggling circumstances for existence.

The purpose of this study is to understand the critical role of hotel information system's EDP(electronic data processing) internal control and quality in hotel industry. This paper examined relationships of hotel information system's internal control and quality with user satisfaction. This study set out the research model of influencing factors and the performance of hotel information system through theoretical studies based on Management Information Systems, and then empirically tested hypotheses related to the model. The model was tested using multi-regression analysis on the sample of 90 respondents who have worked with the hotel information system in hotels. The major results of this study are as follows: First, general control and application control don't have a statistically significant influence on user satisfaction. Second, information quality, system quality and service quality have a statistically significant influence on user satisfaction.
