In this paper, we proposed the ISL for evaluating the security level of Intranet. This method is composed of two parts First, Hacking Scenarios are the hacking stories by hacking/hackers levels. Second, Network Model is composed of the zone and intrusion paths. Our method is very active and practical. We divide ISL into five levels ISL1∼ISL5. Among the levels, ISL5 is the highest security level. Main purpose of this paper is to promote the security of Intranet. In this paper, we designed and analyzed the test-bed for ISL3.

The enterprise service network is composed of internet, intranet and DMZ. The design rationale of Mobile IP is providing of seamless mobility transparency without regarding to the type of network topology and services. However, Mobile IP specification does not include the mobility support in case of using VPN environment and define the access scenarios to get into the VPN intranet without disturbing existing security policy. In this paper, we propose an authentication method using AAA infrastructure and keying material exchange to enable an user in internet to be able to access the intranet through the VPN gateway. Finally, performance analysis for the proposed scheme is provided.

In this paper, an objective of this research is to add convenience to the intranet operating within an educational institution, by setting up a messenger function to enable the faculties and teachers to make better use of the university database via Intranet. With this messenger services, the users can view the information about the members in a group they belong to, and register as friends a group of members they selected from the work group they are in. This function will reduce the cumbersome chores of adding one individual as a friend at a time. This research will enhance the Intranet within an educational institution by integrating new functions. Speciallly, In this paper, it is stored student data by the input form by the JDBC of XML standard data. Also, it is able to search of stored database to web sever from web client by the SQL quary.

Many companies today use information systems to maintain competitive advantage and to give immediate responses to customer requests. Over time, however, many of these companies failed to make the most of such information systems because the users stopped utilizing the system. While many reasons offer explanations to the phenomenon, this study analyzes how usage intention of information system can be enhanced by changing the environment and usefulness of the system from the user's perspective. Active and wide-ranging researches using the Technology Acceptance Model (TAM) have been carried out on an individual's tendency to using new technology. But, many of the studies remain focused on improving user intention by enhancing the ease of use and usefulness of the system under PC applications or Enterprise applications. The personalized intranet system is not only bringing about sweeping changes to a company's information systems environment but also providing users with freedom to design their own working environment, personalization, to Corporate Information Systems (CIS). Results from empirical tests on intranet systems verify that through personalization, a more voluntary information system environment can be created and that by increasing the ease of use and usefulness of the system, users can become more favorable to accepting new technologies and ultimately result in improved usage intention. This study suggests personalization variables and model for implementing a voluntary CIS for information system developers.

The intranet systems used in government sponsored research institutes have been faced with the change of knowledge management under a large scale project. The intranet structure have to be changed to knowledge management system so that every year, the increasing research results information may be effectively administrated by government control system and the competitive power of R&D may be gotten in the society of technical competition. In this paper, we've researched about the change of the times, legacy systems in each organization, the expected efficiency, which have been demanded in government sponsored research institutes through a real implementation process.

This study reviewed influential factors on knowledge sharing and examined to verify how attitude and recognition serve toward security in knowledge-related activities. This two-part study will dedicate to diffusion of knowledge sharing in the ROK Army. The findings indicate that trust and computer self-efficacy are influential factors which cause increase in knowledge sharing intention. Friendly attitude of the members result in strengthening the knowledge sharing in National Defense Intranet. As a result, it could be inferred that organizational and systematic efforts are required to foster the knowledge sharing in the army and policy to induce members' friendly attitude toward security is in need as well.

This paper proposes a new direction of technical highschool in Korea and presents a network model for technical highschool. As a distributed intelligent portal, the network model connects to anywhere and consists of simulated practical exercise in a school's self portal intranet. A title of the simulated practice contents developed in a school would be posted on any open site connected to the network model so that anyone who want to use it in his/her practice class could download to his/her intranet portal site. This mechanism works in two good ways. One is a wide area networkness and another is an easy utilization of broad band width since teacher could use the contents in his/her school's own intranet band width. The paper also emphasize that teachers and educators should make an effort to develop good quality meta-contents.
