This paper introduces Policy Management Tool which was implemented based on Policy Information Model in network suity system. Network security system consists of policy terror managing and sending policies to keep a specific domain from attackers and policy clients detecting and responding intrusion by using policies that policy server sends. Policies exchanged between policy server and policy client are saved in database in the form of directory through LDAP by using Policy Management Tool based on network security policy information model. NSPIM is an extended policy information model of IETF's PCIM and PCIMe, which enables network administrator to describe network security policies. Policy Management Tool based on NSPIM provides not only policy management function but also editing function using reusable object, automatic generation function of object name and blocking policy, and other convenient functions to user.

본 논문에서는 가장 대표적 인 보안 운영 체제인 SELinux를 보다 쉽게 이용할 수 있도록 하는 보안 정책 템플릿과 도구를 설명한다. 제안하는 방법론을 위해 먼저 SELinux를 보다 편리하게 이용할 수 있도록 하기 위해 연구된 기존에 도구들이 가지는 문제점을 분석하였다. 그리고 SELinux를 심도 깊게 분석하여 SELinux에서 이용하는 주체, 객체의 타입 그리고 권한을 객체 타입과 객체별, 권한별로 축약하였다. 이처럼 축약되어 간소화된 객체 타입과 권한을 바탕으로 리눅스 시스템이 이용하는 임의적인 접근통제 형태를 지원하는 보안 정책 템플릿 기술언어를 정의하여 SELinux보안 정책의 복잡성을 개선하도록 하였으며 이를 통해 기존 리눅스 시스템 관리자가 이용하기 편리하도록 하였다. 또한 자동으로 제안된 보안 정책 템플릿 언어로 작성된 보안 정책을 SELinux의 보안 정책으로 변환하는 변환기와 자동으로 정책을 생성하는 생성기를 개발하여 SELinux 이용의 편리성을 최대화 하였다.

The purpose of this study is to analyze comparatively adult literacy surveys of UK, France and Germany who have developed their own adult literacy survey tools independently. The results of the study show that these three countries are similar in that all of them utilize literacy survey tools linked to their own adult literacy policies. The survey tools of the countries are based on the definition of adult literacy as functional literacy and everyday life skill. The criteria of adult literacy levels are differentiated in the context of the countries. And SQC model is adopted as the main model of developing the survey tools. Through this analysis, the following implications could be obtained to improve Korean adult literacy survey. It needs 1) to unify execution subjects of adult literacy survey and adult literacy policy. 2) to develop survey tools reflecting everyday life, 3) to make tools into module form, 4) to pursue the efficiency of cost and utilization of tools.

In Korea, co-utilization of research equipments has been low, even though co-utilization policies for them have been implemented for a long time. This situation results because the policy formation and implementation for the co-utilization of research equipments have been conducted from the perspectives of the policy maker not from those of the researchers and equipment managers. Therefore, this work has been conducted for analyzing the current state of co-utilization of research equipments as well as for discussing the future developments of its more co-utilization in the basic research programs by adopting the bottom approach in policy implementation theory. The research shows that firstly principal investigators, especially professors in universities, have placed a relatively low priority on the co-utilization of research equipments, secondly implementation resources such as high quality technicians and affordable budget for co-utilization are scare, thirdly incentives for the activation of co-utilization in the stage of daily operation of research equipments are lacking. As a result, the study tries to develop a more economic means and information tools for the promotion of co-utilization of research equipments in the perspectives of bottom-up approach in policy implementation theory.

Packet filtering is to filter out potentially malicious network packets. In order to test a packet filtering function we should verify whether security policies are performed correctly as intended. However there are few existing tools to test the function. Besides, they need user participation when generating test cases or deciding test results. Many security administrators have a burden to test systematically new security policies when they establish new policies or modify the existing ones. To mitigate the burdens we suggest a new test method with minimal user articipation. Our tool automates generation steps of the test cases and the test oracles, respectively. By using the test oracles generated automatically, deciding test results is possible without user intervention. Our method realizes an automatic testing in three phases; test preparation phase, test execution, and test evaluation. As a result it may enhance confidence of test activities more highly. This paper describes the design and implementation of our test method and tool.

This study aims at proposing and developing the coastal management policy tool package contingent upon coastal community circumstance so that coastal regional government may enhance the efficiency of coastal administration and reestablish the coastal region master plan systematically. The 8 coastal policy tools of the already-tested U. S. coastal region government will be utilized as the new alternative on behalf of the Korean coastal region government. According to the result of experts survey, these tools especially can be used effectively in the tourism, disaster, restoration, and scenary coastal function types. Although this study is exploratory, it will be expected to contribute as the basic survey results of the successive research and coastal region policy development in Korea.

최근의 정보화환경을 반영한 정보화 관리방법과 도구의 통합 활용에 대한 필요성이 대두되고 있다. 이제는 기존 프로젝트관리 방식만으로는 다원화된 업무, 고객 요구를 충족시키지 못한다. EA, PMO 등 보다 발전된 방법들을 도입하고 활용해야 한다. 그러나 아직도 공공부문 정보화추진에 유용한 개념과 도구들을 통합적으로 활용하지 못하는 것이 현실이다. 공공부분 정보화 정책 환경이 변했지만 아직 현실에 맞게 그러한 사항들이 반영되어 있지 않다. 변화에 맞게 적절한 수단과 방법을 개발하고 지속적으로 발전시키지 못하면 기대한 효과를 거두기도 어렵다. 이제는 CIO 등 정보화를 추진하는 여러 주체가 범정부 EA, IT거버넌스, IT아웃소싱, 각종 지침과 기준 등을 통해 업무생산성을 제고할 수 있는 새로운 접근방법에 대한 제시가 필요하다. 이를 위해 본 연구에서는 EA기반의 PMO제도 적용 활용을 위해 방법론 및 도구의 통합적 활용이 가능한 모델을 제시하고자 한다. 연구방법은 기존 연구결과, 정책, 사업에 대한 문헌연구 및 분석 등을 통해 함의를 도출한다. 결과는 공공부문 정보화 추진 시 생산성 제고를 위한 참조 및 연관되는 유사 IT정책을 추진할 때 방향 정렬(Alignment)에 필요한 시사점 제공과 선행연구로서 의미가 있으리라 기대한다.

This paper reviewed outline of Strategic Niche Management(SNM) and its usefulness and limits as policy tool. SNM is based on Multi Level Perspective(MLP) that traces technological innovation and makes transition of lock-in socio-technical system. This approach is one of systematical then traditional one, market failure approach. SNM had get a attention not only as a analytical frame of technological development, but also tool of radical innovation, although its limits of theoretical and empirical immaturity. SNM could provide a new perspective to analysis and action within urgent needs of alternative innovation policy for aging society, news energy policy for sustainable and disaster policy in danger society.
