With the growing cyber threat to information assets, it has become important to share threat information quickly. This paper examines the sharing of cyber threat information and presents a method to determine the importance of threat indicators in the information sharing market by calculating weights. The analysis was conducted using AHP techniques, with a pairwise comparison of the four factors(attacker & infected system indicators, role indicators, malicious file indicators, technique & spread indicators) and the details of each factor. Analysis shows that malicious file indicators are the most important among the higher evaluation factors and infected system IP, C&C and Smishing are the most important factors in comparison between detailed items. These findings could be used to measure the preference of consumers and the contribution of information provider for facilitating information sharing.

윈도우즈(Windows)에는 서버 메시지 블록(SMB :Server Message Block) 프로토콜을 이용하여 폴더(Folder)를 공유(Share)할 수 있는 기능을 제공 하고 있다. SMB 프로토콜은 네트워크 상 존재하는 노드들 간에 자원을 공유할 수 있도록 설계된 프로토콜이다. 주로 네트워크에 연결된 컴퓨터끼리 파일, 프린터, 포트 또는 기타 메시지를 주고받는데 사용된다. 하지만 이 기능은 대부분 사람들이 잘 알지 못하고 설정 방법을 몰라 사용 하지 않는 경우가 많다. 본 논문에서는 이 공유 폴더 기능을 보다 쉽고 빠르게 설정 할 수 있도록 공유 폴더 기능 향상을 위한 도우미를 설계하고 구현 한다.

PLSI 통합 슈퍼컴퓨팅 서비스 환경에서는 다수의 사이트에서 클러스터 시스템 간 데이터 공유를 위해 글로벌 파일시스템을 사용하고 있으나, 수백 노드 이상의 클라이언트와 파일 서버 간 통신이 이루어지는 병렬 I/O에서 네트워크 병목 현상 이 발생할 수 있다. 따라서, 본 연구에서는 네트워크 병목 현상이 PLSI 글로벌 파일 시스템의 I/O 성능에 미치는 영향을 분석한다. PLSI 글로벌 파일시스템 테스트 베드에서 실험을 통해 네트워크 스위치의 버퍼 크기가 병목 현상을 유발하며, 네트워크 스위치의 버퍼 용량을 증가하여 I/O 성능을 개선할 수 있음을 보여준다.

As people are taking part in more versatile social activities, it becomes more frequent and more important for people to share personal information each other in appropriate level. Unfortunately, although the rapid spread of smart devices and advance of network technologies have brought many applications for information sharing into our hands, they do not provide effective mechanism for sharing personal information on collocated people. In this paper, we introduce an android application named WhoAmI which provides the functionality of sharing personal information on nearby users over Wi-Fi Direct as well as Wi-Fi network environment. According to the predefined access level such as business, community or friend, WhoAmI naturally provides profile information to accessible users. In addition, the information such as music, photo, movie can be effectively shared through the application.

This paper is related to the method for sharing some remote devices through USB/IP on the connected system environment. Sharing the remote devices is actually based on the connection technology using USB which is one way of access methods on virtualized server environment. The users who receive server computing unit might want to connect to remote allocated server with the local devices. We can solve the problem of the access methods related to the sharing devices through USB device emulation. This paper discusses the implementation of USB emulation which is based on personalized services on virtualized server environment. Like this, this paper will share devices on the level of USB device. This research can write to the device directly due to virtualizing the device level.

The riles or intellectual property on computer systems have increasingly been exposed to such threats that they can be flowed out by internal users or outer attacks through the network. The File Outflow Monitoring System monitors file outflows at server by making the toe when users copy files on client computers into storage devices or print them, The monitoring system filters I/O Request packet by I/O Manager in kernel level if files are flowed out by copying, while it uses Win32 API hooking if printed. As a result, it has exactly made the log and monitored file outflows, which is proved through testing in Windows 2000 and XP.

This paper is to describe how to refer to software objects and reuse them through the web browser so that ail the members of the software development team can collaborate with each other on the development procedure, In addition, we describe how to convert the $ ^*$,mdl design information generated from the UML editor into their corresponding XML data, which is arranged to be saved in the relational database system. Furthermore, we provide a facet retrieval system based on which makes use of a object-oriented thesaurus, which supports an integrated environment through which all the project team members can share a lot of source codes and execution files as weil as object files produced from the web-based collaborative development environment. Finally, we have designed and implemented a web version management system that facilitates software developers to manage in their web-based search for the relationship of design informations.

This paper describes how to convert the *.mdl design information generated from the UML editor into the corresponding XML data, which is arranged to be saved in the relational database system. Also, various design informations can be referred and modified to make teams collaborate with each other on the web through the web browser. In addition, we provide an environment in which all the project team members can share a lot of source codes and execution files as well as object files produced from a web-based collaborative development environment. This thesis is the study about a navigation tool system that aids software developers in managing their web-based searches for relationships of design information.
