보안 DNS의 데이터를 이용한 동적 감염 클라이언트 격리 기법

고귀한,노동건 한국정보통신학회 2023 한국정보통신학회논문지 Vol.27 No.6

Even if a secure DNS is used to prevent various DNS attacks, it is very difficult to establish detailed security policies for groups and individuals by distinguishing them who have already been infected. This is because secure DNS is designed with a function at the level of blocking only the access of malicious URLs or IPs in the step of mapping domains to IPs. Most of this isolation and blocking functions are performed by network security solutions such as firewalls. Therefore, in this paper, intrusion indicator data of secure DNS is shared with network access control solutions and next-generation firewalls in the form of Outbound Rest API or Syslog Notification to make infected clients dynamically isolated and blocked. Through this, the suggested scheme effectively blocks not only DNS attacks such as DNS Tunneling, but also the next detour attacks which are performed when DNS attacks are failed, thus prevent duplicate infection of the same internal network users more quickly. 보안 DNS를 사용하여 다양한 DNS 공격에 대비한다 할지라도, 이미 감염된 특정 사용자(단말)나 혹은 다수의 사용자들을 분별하여 그룹 및 개인에게 세밀한 보안 정책을 세우는 것은 매우 어렵다. 보안 DNS는 도메인을 IP로 매핑 시켜주는 단계에서 악성 URL 혹은 IP의 접근 여부 정도만 블록하는 수준의 기능, 즉 서비스에 대한 접근 제어 중심으로 설계되었기 때문이다. 결과적으로 감염된 클라이언트의 DNS 서비스 요청은 제한할 수 있으나, 최종적으로 감염 단말을 내부 격리시키거나, 해커의 외부 C&C서버 통신을 직접적으로 차단하기 위한 외부 네트워크 차단 등의 조치를 취할 수는 없다. 이러한 격리 및 차단 기능은 대부분 방화벽 등의 네트워크 보안 솔루션에서 수행된다. 따라서 본 논문에서는 보안 DNS의 침해 지표 데이터를 네트워크 접근 제어 솔루션 및 차세대 방화벽에게 Outbound Rest API 또는 Syslog Notification 형식으로 공유하여, 감염 클라이언트를 동적으로 격리 및 차단시키고자 한다. 이를 통해 DNS 터널링 등 DNS공격 뿐 아니라, 이것이 막혔을 경우에 행해지는 다음 우회 공격을 효과적으로 제한할 수 있게 되었으며, 같은 내부 네트워크 사용자의 중복 감염을 더 빠르게 예방할 수 있게 되었다.

Subcutaneous panniculitis-like T-cell lymphoma (SPLTCL) which is similar to lobular panniculitis is a subtype of skin lymphoma that is characterized by pleomorphic T cells and benign macrophages. The simultaneous presence of hemophagocytic lymphohistiocytosis (HLH) is the most important and adverse prognostic factor in SPLTCL. SPLTCL is a rare disease with no well-established standard treatment. We report a child with SPLTCL and HLH, who were successfully treated with the modified NHL (non-Hodgkin lymphoma)-BFM(Berlin-Frankfurt-Münster)-90 and HLH-2004 protocols. Patient had persistent fever and subcutaneous masses. SPLTCL with HLH was diagnosed by immunohistochemistry, radiology and laboratory results. SPLTCL with HLH has shown high mortality when treated with a combination of intensive anticancer drugs. Thus, we first administered dexamethasone and etoposide. After this, when we used the modified protocol of NHL-BFM-90 and HLH-2004, patient showed complete resolution of the subcutaneous masses and features of HLH, except for persistent hyperferritinemia. We tried etanercept to reduce high serum ferritin with some effects. In children with diagnosis of SPLTCL with HLH, initiation of immediate and appropriate treatment affects prognosis. Thus, prompt initiation of the agents that can simultaneously control underlying disease as well as secondary HLH could have lead to successful results.

강화된 화재안전기준을 만족하는 고효율 복합단열재 개발

고귀한,최은수,권영철 대한건축학회 2022 대한건축학회논문집 Vol.38 No.7

On September 1, 2018, the building energy saving design guideline was reinforced according to the Zero Energy Building Road Map. On August 6, 2019, due to consecutive large building fires, the building fire safety guideline was also reinforced, and the fire performance of external systems was required in the building finishing system from December 23, 2021. This study examines the reinforced building energy saving design guideline and building fire safety guideline to present the required thickness of various insulations that meet the reinforced building insulation and fire safety guideline. The thickness of non-combustible exterior insulations for buildings above three stories were presented. Non-combustible glass wool above 48K, mineral or rock wool, phenol foam board for the exterior wall of office buildings in central one region should be used as thick as 190mm, 225mm, 120mm, respectively. The high-efficiency hybrid insulation developed in this study can satisfy both the reinforced building fire safety code and reinforced building energy saving design standard with less thickness of 55-75mm. 2020년 1월 1일부터 연면적 1,000m2 이상의 공공건축물들은 제로에너지건축물 인증을 받아야 한다. 2025년부터는 민간건축물도 제로에너지건축물 인증을 받도록 하는 로드맵을 갖고 있다. 제로에너지건축물 로드맵에 따라 건축물 에너지 절약 설계 기준은 2018년 9월 1일자로 강화되었다. 또한 계속되는 대형 건축물 화재로 인해 건축물의 화재안전기준도 2019년 8월 6일자로 강화되었고 2021년 12월 23일부터 건축물 마감재에 대한 실물화재시험을 거치도록 하고 있다. 본연구에서는 강화된 건물의 단열 및 화재안전기준을 조사하고, 이들을 만족할 수 있는 다양한 단열재들의 두께를 제시하였다. 또한 3층이상의 건축물의 외단열재로 사용할 수 있는 준불연 단열재별 소요두께를 제시하였다. 본연구에서 개발된 준불연 복합단열재는 기존 단열재 대비 절반이하의 두께로 동일한 단열성능을 만족하며, 실물화재시험도 통과하는 것을 확인하였다.

This research is for the characteristics of ecological expression appeared in Interactive space. it is aimed to investigate on the characteristics of expression and the selection of ecological theory on interactive space in between relationship. and architecture is not the old building adapting new technology. In order to take the role as new architectural paradigm in space, environment and technology, it has to develop technology continuously and experimental architecture at the same time. it must have coevolution of architectural field and others through organic network. by that, the evolution of space will be in the way that combines space which is responded to human emotion is to have correlation about ecological theory. From the ecological point of view, interactive space is artificially constructed space, but it comes to have potential to approach natural aspect by interaction to human. interactive space is not imitation to ecology but that has interaction element by Space(structure, space form, material, light, floor), Vector(technology, algorithm, process), Human(five-senses, movement, response, reaction). At this point, Space combine the three elements integrates nature with art smoothly. It has possibility to make it being recognized as an element of ecosystem.

The concept of User experience has been an important issue both in academic and practical areas in recent years. Interactive space became one of the major design paradigms. For elevating the interactive effect, we need user-centered design methodology which uses the influential factors on the interactivity. As, well developed information technology made a lot of changes to various fields of our society, interactive space with the concept of HCI became a big issue in environmental design field. In this interactive space, various types of informative factors of the given space are sent using sensor and computer networking technology to the main system. So, a user"s movement in the space in more than just a movement itself-user"s movement now forms a important spatial structure that leads the narrative of the space. in this research, I will come up with the problems that the interactive space has right now, and analyze what the public space space must have, and combine them with interactive space by HCI theory.
