Partial transactions which use computer networks are formed in the cyberspace due to rapid progress of communication and computer technology. Electronic business transactions have security problems according to the special quality of opening networks, while it can be approached easily by anyone without being tied to time and places through Internets. To revitalize the electronic business transactions, security technology which can establish its security and trust is the prior task and both safe information communication and better information security service offer are essential factors. The method to exchange information through Internets must be made after confirming one another's exact connection in the mutual identity certification to prevent a lot of threat which can occur in the use of password techniques. To satisfy these electronic business transactions, we intend to increase understanding of authentication algorithm provided with authentication function of messages and users as well to plan safety and trust of business information and contents in the electronic business transactions.

Due to the increasing complexity of the information systems environment, modern information systems are facing more difficult and various security risks than ever, there by calling for a higher level of security safeguard. In this paper, an information technology security risk management model, which modified by adopting the concept of business processes, is applied to client/server distributed systems. The results demonstrate a high level of risk-detecting performance of the model, by detecting various kinds of security risks. In addition, a practical and efficient security control safeguard to cope with the identified security risks are suggested. Namely, using the proposed model, the risks on the assets in both of the I/O stage(on client side) and the request/processing stage(on server side), which can cause serious problems on business processes, are identified and the levels of the risks are analyzed. The analysis results show that maintenance of management and access control to application systems are critical in the I/O stage, while managerial security activities including training are critical in the request/processing stage.

IT비즈니스의 전략적 연계가 강화됨에 따라 금융서비스에서 IT의존도는 높아지고 있다. 안전하고 신뢰된 금융서비스를 제공하기 위해서는 지속적인 정보보호활동을 수행해야 하며, 이에 관한 조직의 정보보호 업무성과 측정은 의사결정 및 경영지원 측면에서 유용하다. 본 논문은 정보보호관리체계(K-ISMS)와 금융IT 부문 정보보호 업무 모범규준의 평가기준을 기반으로 핵심성공요인(CSF, Critical Success Factor)과 핵심성과지표(KPI, Key Performance Indicator)를 도출한다. 이는 정보보호정책 준수에 유의한 영향을 주는 핵심성과지표를 판별하는 논리적 근거를 제공하며, 금융IT 정보보호 역량을 강화하기 위한 정책을 수립하기 위한 기초자료로 활용할 수 있다.

Enormous losses of shareholders and consumers caused by the risks threatening today's business (e.g., accounting fraud and inside trading) have ignited the necessity of international regulations on corporate ethics and internal control, such as Basel II and SOX. Responding to these regulations, companies are establishing governance system, applying it consistently to the core competency of the company, and increasing the scope of the governance system. Recently occurred security related incidents require companies to take more strict accountability over information security. One of the results includes strengthening of legislation and regulations. For these reasons, introduction of information security governance is needed. Information security governance governs the general information security activities of the company (establishment of information security management system, implementation of information security solutions) in the corporate level. Recognizing that the information security is not restricted to IT domain, but is the issue of overall business, this study develops information security governance framework based on the existing frameworks and systems of IT governance. The information security governance framework proposed in the study include concept, objective, and principle schemes which will help clearly understand the concepts of the information security governance, and execution scheme which will help implement proper organization, process and tools needed for the execution of information security governance.

정보보호 전담조직은 IT 부서 산하에 편성되어있는 것이 일반적이었으나 정보보호의 중요성이 증대됨에 따라 전사적 보안을 위한 정보보호 전담조직의 편성이 중요한 이슈로 대두되고 있다. 국내 금융권에서도 전자금융거래법 개정안을 통해 CIO와 CISO를 분리하는 등 정보보호 전담조직의 분리에 대한 필요성이 증대되고 있다. 하지만 현재 정보보호 전담조직 하부구조에 대한 연구는 활발히 진행되고 있으나 편성방법에 대한 연구는 미흡하다. 따라서 본 논문에서는 효과적인 정보보호 전담조직의 편성을 위해, 상황적 접근방법을 통하여 기업의 비즈니스 위험도와 IT 의존도를 기준으로 정보보호 전담조직 편성모델을 제시하였다. 또한 정보보호 전담조직이 소속될 부서를 기획 조정 부서, 내부통제 부서, 내부관리 부서, IT 부서로 분류하고 각 부서에 편제되어있을 경우의 장단점을 분석하였다.

The basic legislations regulating the private security in Korea are Private Security Business Act and Private Policeman Act. But this dualistic system of private security causes difficulties in unity and efficiency of private security operation and makes it complicated to supervise each personnel with effect. Besides despite similar service and duty, there is all the difference between private security guard and private policeman in regard of social position, pay, authority, and so on. Therefore it is suggested that the two Acts should be unified and the united private security act should be enacted. Legislating new private security act will lead to considering the detail legislative definition on qualification of personnels and business range.

Corporation's valuable intelligent asset is being threatened from the skills of threatening subject that has been evolved along with the growth of the information system and the amount of the information asset. Domestically, attempts of various private information attacks, important information extortion, and information damage have been detected, and some of them have abused the vulnerability of security of information system, and have become a severe social problem that generates security incident. When accessing to the security, most of companies used to establish a strategy with a consistent manner and a solution plan. However, this is not a proper way. The order of priorities vary depending on the types of business. Also, the scale of damage varies significantly depending on the types of security incidents. And method of reaction and critical control point vary depending on the types of business and security incidents. In this study, I will define the security incidents by their types and preponderantly examine how one should react to those security incidents. In this study, analyzed many types of security accidents that can occur within a corporation and an organization considering various factors. Through this analysis, thought about factors that has to be considered by corporations and organizations when they intend to access to the information security. This study focuses on the response methodology based on the analysis of the case analysis of the leakage of industrial secret and private secret other than the conceptual response methodology that examines the way to prevent the leakage of the industry security systems and the industry information activities. And based on these factors, want to be of help for corporations to apply a reasonable approach when they establish a strategy to information security.

People have transferred their business model from traditional commerce to e-commerce in recent decades. Both shopping and payment can be completed through the Internet and bring convenience to consumers and business opportunities to industry. These trade techniques are mostly set up based on the Secure Sockets Layer (SSL). SSL provides the security for transaction information and is easy to set up, which makes it is widely accepted by individuals. Although attackers cannot obtain the real content even when the transferred information is intercepted, still there is risk for online trade. For example, it is impossible to prevent credit card information from being stolen by virtual merchant. Therefore, we propose a new mechanism to solve such security problem. We make use of the disposable dynamic security code (DSC) to replace traditional card security code. So even attackers get DSC for that round of transaction, they cannot use it for the next time. Besides, we apply visual secret sharing techniques to transfer the DSC, so that interceptors cannot retrieve the real DSC even for one round of trade. This way, we can improve security of credit card transaction and reliability of online business. The experiments results validate the applicability and efficiency of the proposed mechanism.
