A new password authentication method Is proposed in this paper for the purpose of providing web page authors the convenience in deploying password-protected Web realms at a web server. According to this method. a web realm is mapped to a secret directory at the web server. in which access-controlled web pages are stored. A password is used to construct the name of the secret directory. A javaScript code is embedded in a sign-in web pageoutside the secret directory, which converts the user-entered password into the directory name and forms a complete URL pointing to an access-controlled web page inside the secret directory. Thus, only users knowing the password can compose a valid URL and retrieve the access-controlled web page. Using this method, web page authors can deploy password-protected web realms in a server-independent manner.

This paper classifies technical, administrative and physical areas of defects and advices made by an external audit (ISO27001) and internal audit (performed by a security team) in a company which has the management system of information security. With the classified data it finds the correlation between the budget and investment of information security, and analyze the correlation. As a result of the analysis, it has been found that as time goes on there is a consistent correlation between a administrative area and technical area of security. Specially, it has been confirmed that the relation between the scale of the budget which is not executed and the number of the defects and advices made by the audit is in direct proportion. Therefore, in this paper, so as to provide a model that can be used for validating the effectiveness of the protective investment information by statistically calculating the similarity based on the results of correlation analysis. This research is intended to help that a company makes a precise decision when it establishes a policy of information security and systematic methodology of the investment in information security.

최근의 인터넷을 통한 사이버 공격 유형은 시스템 위주의 공격에서 네트워크 공격으로 변화하고 있다. 이에 따라 망을 소유하고 인터넷 서비스를 제공하는 ISP 관점의 보안이 중요한 변수로 등장하기 시작하였다. 본 논문에서는 1.25 인터넷 대란과 같은 국가차원의 사태 재발 방지를 위하여 현재 인터넷망의 취약성을 분석하고 이에 대한 보안 해결책으로서 보안 시스템의 성능, 기능 관점의 보안 이슈와 서비스 관점에서 보안 요구 사항을 살펴보았다. 또한 이를 종합하여 네트워크 영역 관점에서 앞으로 중점적으로 다뤄야 할 보안 연구 분야를 제시하였다.

매년 폭발적 성장률을 유지하고있는 인터넷 기반의 B2B 전자상거래 분야는 현재 그 영역을 기업대 기업, 국가 대 국가의 영역으로 확대하고 있다. ebXML로 대변되는 차세대 XML 기반의 국제적 표준 전자상거래 프레임워크의 활발한 표준화를 통해 이는 더욱 가속화될 전망이다. 그러나 다양한 보안 요소를 만족하는 안전한 거래를 위해 선행되어야 할 XML 기반의 전자상거래 모델에 최적화된 보안 기술에 대한 연구가 다른 분야에 비해 미진한 것이 현실이다 따라서 본 연구에서는 ebXML 메시징 및 등록기/저장소를 중심으로 보안 요소를 분석하고 XML기반의 보안 기술 적용 시스템을 설계함으로써 신뢰성 있고 안전한 ebXML 거래 모델을 제시한다.

Recently, the Ministry of National Defense has included embedded software for weapon systems as targets for the Defense cyber security. The Concept has been extended and evolved from the cyber security area that was previously limited to the information domain. The software is becoming increasingly important in weapon systems, and it is clear that they are subject to cyber threats. Therefore, We would like to suggest a improvement direction by diagnosing problems in terms of cyber security of the weapon systems for the life cycle. In order to improve cyber security of weapon systems, comprehensive policy including the weapon embedded software management should be established and the involved stakeholder should be participated in the activities.

This study introduces server-side security-oriented framework for smart financial service. Most of domestic financial institutions providing e-banking services have employed server-side framework which implement service-oriented architecture. Because such architecture accommodates business and security requirements at the same time, institutions are struggling to cope with the security incidents efficiently. The thesis suggests that separating security areas from business areas in the frameworks makes users to be able to apply security policies in real time without considering how these policies may affect business transactions. Security-oriented frameworks support rapid and effective countermeasures against security threats. Furthermore, plans to avoid significant changes on existing system when institutions implement these frameworks are discussed in the report.

The purpose of this study was to add CPTED to the information security area. The control items of ISO 27001 (11 types) and the application principles of CPTED (6 types) were mapped. And the relevance between the items was verified through the FGI meeting through 12 security experts. As a result of the survey, the control items with a relevance of at least 60% on average are security policy, physical and environmental security, accident management, and conformity. As a result, the comprehensive policy was shared with CPTED's items as a whole. The specialized control items are security organization, asset management, personnel security, operation management, access control, system maintenance, and continuity management. However, specialized control items were mapped with each item of CPTED. Therefore, information security certification and septed are related. As a result, environmental security can be added to the three major areas of security: administrative security, technical security, and physical security.

It has become more difficult to correspond a cyber attack quickly as patterns of attack become various and complex. However, current security mechanism just have passive defense functionalities. In this paper, we propose new network security mechanism to respond various cyber attacks rapidly and to chase and isolate the attackers through cooperation between security zones. The proposed mechanism makes it possible to deal effectively with cyber attacks such as IP spoofing, by using active packet technology including a mobile code on active network. Also, it is designed to hove more active correspondent than that of existing mechanisms. We implemented these mechanisms in Linux routers and experimented on a testbed to verify realization possibility of attacker response framework using mobile code. The experimentation results are analyzed.
