웹 서비스를 기반으로 구축된 IT 환경에서 Dynamic Web page 를 동작하도록 하는 것이 CGI(Common Gateway Interface)이다. 이런 CGI 를 사용하는 Web page 에서는 XSS(Cross Site Scripting)에 취약점을 가지고 있다. XSS 의 취약점을 이용하여 Web page 의 변조, Cookie 의 가로채기 등의 악의적인 행동으로 인해 많은 피해사례가 있다. 기존의 연구들은 이러한 문제를 해결하기 위해서 게시판 입력 값을 체크하여 Meta character 를 필터링 하는 방법으로 XSS 공격을 대응하였다. 그러나 이러한 방법은 각 페이지 마다 필터링 스크립트를 사용하기 때문에 웹 서버의 성능에 많은 부하를 초래 하는 단점이 있었다. 따라서 본 논문에서는 이러한 웹 서버의 부하를 줄이기 위해 필터링 스크립트를 DLL(Dynamic link library) 화 시켜 모듈화된 함수를 각 페이지에서 호출하여 사용함으로써 웹 서버의 성능 향상을 제안 한다.

Web 3.0 is the next-generation of the World Wide Web and is included two main platforms, semantic technologies and social computing environment. The basic idea of web 3.0 is to define structure data and link them in order to more effective discovery, automation, integration, and reuse across various applications. The semantic technologies represent open standards that can be applied on the top of the web. The social computing environment allows human-machine co-operations and organizing a large number of the social web communities. In the recent years, recommender systems have been combined with ontologies to further improve the recommendation by adding semantics to the context on the web 3.0. In this paper, we study previous researches about recommendation method and propose a recommendation method based on web 3.0. Our method scores documents based on context tags and social network services. Our social scoring model is computed by both a tagging score of a document and a tagging score of a document that was tagged by a user's friends.

Temperley-Lieb algebras had been generalized to web spaces for rank 2 simple Lie algebras which led us to link invariants for these Lie algebras as a generalization of Jones polynomial. Recently, Geer found a new generalization of Jones polynomial for some Lie superalgebras. In this paper, we study the quantum sl(1|1) representation theory using the web space and find a finite presentation of the representation category (for generic q) of the quantum sl(1|1).

DSRC(Dedicated Short Range Communications), which is a radio mobile communication protocol in ITS, is suited for traffic related information services. But in WAC(Wide-Area wireless communications), we could consider a conventional communication infrastructure in the case of supporting other applications besides ITS. Especially considering the current the trends to introduce wireless internet service into the mobile communication network, wireless internet service in ITS system is valuable. Although ITS LLC(Logical Link Control) protocols recommended by Europe and Japan are effective for traffic related services, it is not suitable for services related with geographical information, image or internet. That is because the data traffic characteristics is changed according to service types. Therefore we suggest a logical link control algorithm effective for traffic information related services as well as internet web service, and analyze its performance. As a result of numerical analysis and simulation, proposed algorithm shows larger performance improvements. For traffic information related services, the performance of DSRC LLC recommended by Europe and Japan is the same as that of proposed LLC protocol. However, for wireless internet web service, the performance of proposed protocol is much better than that of LLC protocol used in Europe and Japan.

Recently, trends of information technology development include offerings of service for personalization, intelligence, and convergence. The research suggested a new tour system that tourists can make their tour packages by applying Semantic Web technology. The system includes ontologies and inference rules for offering intelligent and personalized service. Our system called MYT (Make Your Tour-package) was successfully demonstrated by employing realistic scenarios. Current version of the MYT system needs manager's intervention to link and integrate automatically ontology subsystem and Web service. In further study, the MYT will be extended to the system including a component integrating automatically subsystems and a component capturing and processing context data from RFID/USN.

Using user monitoring techniques on web, marketing decision makers in cyber shopping malls can gather customer behavior data as well as sales transaction data and customer profiles. In this paper, we present a marketing rule extraction technique for customer behavior analysis in cyber shopping malls, The technique is an application of market basket analysis which is a representative data mining technique for extracting association rules. The market basket analysis technique is applied on a customer behavior log table, which provide association rules about web pages in a cyber shopping mall. The extracted association rules can be used for mall layout design, product packaging, web page link design, and product recommendation. A prototype cyber shopping mall with customer monitoring features and a customer behavior analysis algorithm is implemented using Java Web Server, Servlet, JDBC(Java Database Connectivity), and relational database on windows NT.

인터넷의 확산과 더불어 사용자가 즐겨 찾는 뵐 사이트의 수도 증가되고 있다. 현재 이러한 웹 사이트들은 웹 브라우저의 즐겨찾기에 등록하여 관리되고 있다. 등록된 즐겨찾기 목록은 로컬 브라우저에 한정되어 있어서 다른 장소에서 이 즐겨찾기에 등록된 정보를 이용하려고 할 경우 번거로움이 있다. 따라서 인터넷이 연결된 어디에서나 자신의 즐겨찾기를 이용할 수 있고 다른 사용자들과 유용한 사이트 정보를 공유할 수 있는 도구를 제공하는 것이 바람직하다. 본 논문에서는 웹기반 즐겨찾기 컴포넌트인 LinkManager를 개발함으로써, 인터넷이 연결된 어디에서나 자신의 즐겨찾기를 이용하고 관리할 수 있도록 지원하였다. 추가로 LinkManager는 협업지원 시스템과 같은 웹어플리케이션에 적용될 경우 그룹의 링크를 맴버들이 공유할 수 있어서 작업의 효율을 높일 수 있다.

Malicious code distribution on the Internet is one of the most critical Internet-based threats and distribution technology has evolved to bypass detection systems. As a new defense against the detection bypass technology of malicious attackers, this study proposes the automated tracing of malicious websites in a malware distribution network (MDN). The proposed technology extracts automated links and classifies websites into malicious and normal websites based on link structure. Even if attackers use a new distribution technology, website classification is possible as long as the connections are established through automated links. The use of a real web-browser and proxy server enables an adequate response to attackers' perception of analysis environments and evasion technology and prevents analysis environments from being infected by malicious code. The validity and accuracy of the proposed method for classification are verified using 20,000 links, 10,000 each from normal and malicious websites.

This article presents an overview of the key technologies in the communications payload of broadband LEO satellite communications systems. In recent years, new developments have been realized for LEO satellite communications. SpaceX's Starlink, a technology leader in this field, offers premium services with satellites carrying in-house developed communications payloads. OneWeb, Amazon, Telesat, and Boeing are also developing LEO satellite communications payloads. The communications payload consists of user link antennas, inter-satellite link communications equipment, feeder link antennas, and a digital processor. Highly sophisticated technologies of compact active phased array antennas for generating multiple hopping beams and light laser communication equipment for ultra-high-speed inter-satellite communication will be applied to next- generation payloads.
