Several security systems(firewall, intrusion detection system, vaccine for malicious codes and so on), whose purposes are to prevent the external information security threat, have gathered more technological concerns. However, they are little effective for the area of defending the internal information security threat which occurs more frequently and results in much more monetary damages. In this paper, a system for internal surveillance and control on the use of information systems is suggested and described with its architecture, features, necessary functions and development methods. And a case system is introduced to show the reality of this paper.

현대 감사에서 한정된 자원으로 통제 및 감사의 효과(목적)를 최대로 달성하기 위해 통제요소의 상대적인 중요도 파악 및 우선순위 설정이 필요해짐에 따라, 감사인의 판단에 기초한 정보시스템 내부통제 요소의 중요도 평가가 감사에 있어 매우 중요한 관건이 되고있다. 특히 조직에 LAN이 보급되면서 LAN의 환경적 특징으로 인해 통제시스템이 취약해 질 가능성과 이에 대한 보완 방안에 관한 연구가 시작되고 있는데, AHP(Analytic Hierarchy Process)모델을 응용한 Harper(1988)의 중요도 평가에 관한 연구는 시스템 감사인의 LAN 통제 평가의 효율화에 기여할 수 있다는 평가를 받고 있다. 그러나 Harper이 연구에서는 모델에 LAN을 고려한 시스템 감사 목적 (통제설치 기준)의 중요도를 고려하지 못하여 모델에서 결정된 통제요소의 중요도 순위가 부적절할 가능성을 갖는다. 만약 통제요소의 중요도가 부적절할 경우, 이는 LAN 통제 평가와 관련한 시스템 감사의 효율화 뿐 아니라 효과성을 해칠 가능성을 갖게된다. 본 연구는 이와같은 논의를 토대로 기존 연구가 갖는 문제점을 보완, LAN 통제요소의 적절할 평가 방안에 관한 연구를 진행할 것이다.

Network Access Control system of medical asset protection solutions that installation and operation on system and network to provide a process that to access internal network after verifying the safety of information communication devices. However, there are still the internal medical-data leakage threats due to spoof of authorized devices and unauthorized using of users are away hours. In this paper, Network 2-Factor Access Control Model proposed for prevention the medical-data leakage by improving the current Network Access Control system. The proposed Network 2-Factor Access Control Model allowed to access the internal network only actual users located in specific place within the organization and used authorized devices. Therefore, the proposed model to provide a safety medical asset environment that protecting medical-data by blocking unauthorized access to the internal network and unnecessary internet access of authorized users and devices.

지난 2004년 6월 24일에 공표된 신BIS 자기자본규제제도에 의거 회원국 은행들에 대한 체계적인 위험관리가 강화되는 상황에서 우리나라도 2009년부터 모든 은행이 신BIS기준을 도입및 적용할 예정이다. 신BIS협약은 운영리스크(부적절한 내부절차, 직원, 시스템)에 대해서도 리스크를 측정하여 은행의 소요 자기자본에 반영토록 하고 있다. 따라서 본 연구자는 은행의 조직환경 변수들이 조직유효성에 영향을 미치고 이들이 또한 내부통제절차의 상시 유효성에 영향을 미치는 지 알아보기 위하여 국내 소재 은행원들을 대상으로 실증분석함으로써 은행들이 효율적인 내부통제를 통해 금융사고를 미연에 방지하고 은행자산의 건전성에 기여하기 위한 지침을 제시하는 관점에서 연구를 진행하였다. 연구결과, 연구모형에서 예상한 바와 같이 조직환경이 내부통제유효성에 직접적으로 영향을 미치지만 조직몰입도나 집단응집력과 같은 조직유효성을 매개로 하여 내부통제유효성에 더욱더 영향을 미치고 있었다. 이러한 점에 비추어 본 연구의 결과를 토대로 은행내 중간관리자의 성향에 따라 개별조직 구성원들의 행동양식이나 가치관에 영향을 미칠 수 있는 현실을 감안하여 장기적인 안목에서 양질의 리더십, 조직문화 그리고 분위기 등 조직환경을 리드해 나갈 수 있도록 관리자들에 대한 교육훈련 및 소양교육을 지속적으로 펼쳐나가는 것이 중요하다고 본다.

This study conducted an empirical analysis of SSE-listed companies to verify the effects of evaluation and disclosure of internal control systems on the agency costs management and controlling shareholders. Agency costs can affect the valuation of accounting information as asymmetry of information in the relationship between a company and its stakeholders, or induce financial costs as an adverse selection. If the firm's agency costs are reasonable, the valuation of the company can also move in a relatively positive direction. In this study, the evaluation information of the internal control system was analyzed through sales management ratio and equity ratio as substitute variables to analyze the relationship between management and agent costs of the controlling shareholders. In addition, independent control ratio, capital balance ratio, and company scale were used as control variables, as a result of the analysis, the evaluation information of internal control was found to be related to the agency costs of managers and governance structure. This study can be conducted to positive factors in evaluating the reliability and corporate value of accounting information according to the evaluation of internal control of SSE-listed companies and helps to understand the financial reporting environment.

As the trend towards expanding the functions of modern governments continues, there are also problems such as misconduct and waste that arise as government activities and operations increase. To solve these issues, countries are establishing and developing internal control mechanisms. In this process, the U.S. Inspector General system has been operating for over 40 years with the aim of balancing and overseeing the government and the legislature. Accordingly, this study analyzed in detail the development process of the inspector system, one of the internal control systems promoted by U.S. government agencies, the formation of an inspector community, and the deployment, cooperation, and supervision of inspectors. As a result, the internal control system of domestic government agencies also needs to continue research so that the government and parliament can maintain close relations and introduce the inspector system according to the domestic situation.

Information society in recent times, lots of important information have been stored in information systems. In this situation, unauthorized person can obtains important information by piggy-backing and shoulder surfing in specific area of organization. Therefore, in this study, we proposed network group access control system by combining RFID and infrared-ray for blocking information leakage due to unauthorized access by internal threats and enhancing personnel security. So it can provides a more secure internal network environment.

This study analyzed through GEM-listed companies for verifying the interrelationship between positive and negative impacts on accounting information GEM-listed companies, whether venture firms operate the internal control operation system stably. Hong Kong's GEM listed company is a securities market similar to Korea's KOSDAQ market. To analyzing this study, used regression analysis method through internal control index to evaluate the operation of internal control system and discretionary accruals to evaluate the quality of accounting information. In this study, because profit adjustments used to realize through discretionary accruals, so analyzed using the modified Jones model to check whether the management deliberately transformed the company to realize future profits. In the empirical analysis, the correlation between the internal control index and the discretionary accruals to assess the quality of accounting information was able to find highly correlated. This study can provide useful guidance for evaluating the form and value of profit management of venture firms in the future, also would expect to help understand the financial environment of emerging venture firms.

The propose of study is to examine the characteristics of companies with high possibility to form an internal control weakness using forecasting model. This study use the actual listed/unlisted companies' data from K_financial institution. The first conclusion is that discriminant model is more valid than logit model to predict internal control weak companies. A discriminant model for predicting the vulnerability of internal control has high classification accuracy and has low the Type II error that is incorrectly classifying vulnerable companies to normal companies. The second conclusion is that the characteristic of weak internal control companies have a low credit rating, low asset soundness assessment, high delinquency rates, lower operating cash flow, high debt ratios, and minus operating profit to the net sales ratio. As not only a case of listed companies but unlisted companies which did not occur in previous studies are extended in this study, research results including the forecasting model can be used as a predictive tool of financial institutions predicting companies with high potential internal control weakness to prevent asset losses.
