As measures for protecting users and ensuring security of electronic financial transactions, such as online banking, financial institutions in South Korea have implemented network segregation policies. However, a revision of such domain-centered standardized network segregation policies has been increasingly requested because of: 1) increased demand for remote work due to changes resulting from COVID-19 pandemic; and 2) the difficulty of applying new technologies of fintech companies based on information and communications technologies (ICTs) such as cloud services. Therefore, in this study, problems of the remote work environment arising from the network segregation policy currently applied to the financial sector in South Korea and those from the application of new ICTs such as fintech technology have been investigated. In addition, internal network protection policies of foreign financial sectors, such as those of the United States, United Kingdom, European Union, and Russia, and internal network protection policies of non-financial sectors, such as control systems, have been analyzed. As measures for the effective improvement of the current network segregation policy, we propose a policy change from domain-based to data-centric network segregation. Furthermore, to resolve threats of hacking at remote work, recently emerging as a global problem due to COVID-19 pandemic, a standard model for remote work system development applicable to financial companies and a reinforced terminal security model are presented, and an alternative control method applicable when network segregation is not applied is proposed.

이 연구의 목적은 2009년부터 본격적으로 추진되어온 도서관정책의 성과와 한계를 지역 공공도서관정책의 건강성에 대한 점검을 통해 가늠해 보는 데 있다. 이를 위해, 지역 공공도서관정책의 법적 근거가 되는 도서관 조례와 내용적 길잡이가 되는 시행계획부터 점검하였다. 이어서 기존 정책이 지역 공공도서관에 가져온 긍정적 변화와 그 이면에 공존하는 부정적 모습을 밝혀내었다. 마지막으로, 기존 정책에 내재하는 구조적 한계에 집중하면서 정책의 건강성을 제고하기 위한 실사구시적인 처방을 모색하였다.

Policies are collections of general principles specifying the desired behavior and state of a system. Network management is mainly carried out by following policies about the behavior of the resources in the network. Policy-based (PB) network management supports to manage distributed system in a flexible and dynamic way. This paper focuses on configuration management based on Internet Engineering Task Force (IETF) standards. Network security approaches include the usage of intrusion detection system to detect the intrusion, building firewall to protect the internal systems and network. This paper presents how the policy-based framework is collaborated among the network security systems (intrusion detection system, firewall) and intrusion detection systems are cooperated to detect the intrusions.

이종의 분산환경에서 다양한 보안시스템에 대한 효율적인 보안 관리를 위해서 관리자는 보안 시스템들이 설치된 네트워크 환경에 대한 사전에 전문적인 보안 지식을 갖고 있어야하며, 개방형 네트워크 환경의 경우 새로운 보안시스템이 추가되면 새로운 보안 정책과 기술을 적용해야 한다. 이는 전산망 운영 기관의 보안 관리 비용을 가중시키며 체계적이고 일괄적인 보안 정책 및 기술 구현을 불가능하게 하여 오히려 보안 문제를 야기시키는 역기능을 초래할 수 있다. 그리고, 보안 제품의 개발과 공급이 다수의 공급자에 의해서 공급되므로 서로 상이한 특성을 갖는 보안 시스템들로 구성된 보안 관리 구조의 효율적인 운용과 유지에 상당한 어려움이 있다. 이에 본 논문에서는 이종의 보안시스템을 관리하는 통합보안시스템의 보안정책을 Z-Notation을 통해서 정의하고 통합관리에서 발생되는 정책 충돌 문제를 대표적인 보안시스템인 침입차단시스템(Firewall : 방화벽)을 대상으로 모델링하고 이를 해결하는 알고리즘을 제시하고자 한다.

Recently, an SSD with hybrid buffer memories is actively researching to reduce the overall latency in server computing systems. However, existing hybrid buffer policies caused many swapping operations in pages because it did not consider the overall latency such as read/write operations of flash chips in the SSD. This paper proposes the clock with hybrid buffer memories (CLOCK-HBM) for a new hybrid buffer policy in the SSD with server computing systems. The CLOCK-HBM constructs new policies based on unique characteristics in both DRAM buffer and NVMs buffer for reducing the number of swapping operations in the SSD. In experimental results, the CLOCK-HBM reduced the number of swapping operations in the SSD by 43.5% on average, compared with LRU, CLOCK, and CLOCK-DNV.

Damage to the natural environment is becoming increasingly complex in modern society, expanding to impact not only the environment but also society and the economy. Various systems and policies based on sustainability have been promoted internationally. Legal systems and policies based on evaluation systems such as land environment assessment and urban ecological status maps, have been implemented in Korea. However, most of Korea institutions and policies related to the natural environment have been directed toward the conservation of the natural environment, and restricted to in simple theoretical frameworks with various limitations. Therefore, this study analyzed the definition and value of the natural environment for a fundamental conceptual approach to the valuation of the natural environment. Based on this, we modeled the policy process for a flexible evaluation system suitable for the actual situation of Korea natural environment through a review of the integration of environmental policy proposed in Europe.

Being Changed the international fisheries situation to begin the WTO, it is important to increase the international competition power in fisheries environment to related our country. One of most important work is to build the Fisheries Information Systems(FIS), FIS should give to increase the efficiency of fisheries policies, to share the fisheries informations, and to increase the competitive power of international fisheries environment. On the conclusion, this paper has four expect effects to build the FIS. First, fisheries information will be supplied the clean fisheries policies based on FIS. Second, The Data Warehouse of FIS will be contributed to improve the criterion and statistics of fisheries data. Third, Fisheries Administration will increase the service between fisheries institutes using the FIS. Finally, fisheries administration will use the fisheries data efficiently as integrating the fisheries data into information systems.

Family policy and parents support policy are similar in that they are both object-oriented, not function-oriented. An object-oriented policy, different from a function-oriented policy, is demander-oriented in that it combines the existing policies from the object-perspective. Parents support policy and family policy are very similar in that they are both object-oriented policies and emphasize the perspective of the demanders: the parents and family. As is the case for all policies, if the ministries concerned with the policies are different, the projects are promoted from different delivery systems, so it is difficult to link them together. However, it is essential to relate the two policies because a partnership between families and schools, the subjects of the policy, is the basis of healthy family and a healthy society. Therefore, this research analyzes the current family policy and parents support policy, and examines the necessity and possibility of relating the two policies. This analysis is meaningful in that it seeks consilience between the policy areas, and seeks a new demander-oriented paradigm construction system.

행정안전부 전자정부국은 행정정보시스템의 디지털정보 보존을 본격 추진하기 위하여 전자정부법 개정을 추진하고 있다. 디지털정보의 보존은 공공기록물법에 규율된 사항이라 개정이 될 경우 양 법률 간의 갈등이 예상된다. 이러한 상황에서 공공기록정책의 전환은 더 이상 미룰 수 없는 과제가 되었다. 현재의 공공기록정책은 디지털정보를 관리하기에 미흡하다. 이 연구의 목적은 디지털 전환에 대응한 공공기록정책의 방향을 제시하는 것이다. 이를 위하여 최근 공공기록정책이 어떠한 변화양상을 보이는지 영국과 호주를 사례로 분석하였다. 정보관리로의 확장, '디지털 연속성' 관리, 자산으로의 정보의 관리, 정보거버넌스 체계의 구축이라는 특징을 도출하였으며, 행정정보시스템의 디지털정보의 경우 보존과 활용 목적을 동시에 충족시켜야 한다는 점에서 기록자산으로서의 정보관리 접근법을 강조하였다.
