Implementation of the Basic System in the Cloud Type Virtual Policy Based Network Management Scheme for the Common Use between Plural Organizations

In the current Internet-based systems, there are many problems using anonymity of the network communication such as personal information leak and crimes using the Internet systems. This is because the TCP/IP protocol used in Internet systems does not have the user identification information on the communication data, and it is difficult to supervise the user performing the above acts immediately. As a solution for solving the above problem, there is the approach of Policy-based Network Management (PBNM). This is the scheme for managing a whole Local Area Network (LAN) through communication control of every user. In this PBNM, two types of schemes exist. The first is the scheme for managing the whole LAN by locating the communication control mechanisms on the course between network servers and clients. The second is the scheme of managing the whole LAN by locating the communication control mechanisms on clients. As the second scheme, we have been studied theoretically about the Destination Addressing Control System (DACS) Scheme. By applying this DACS Scheme to Internet system management, we realize the policy-based Internet system management. In this paper, we show the DACS system theoretically.

A personal portal, which is an entrance wherein each user can acquire the information that s/he is interested in on a network, is often used as an alternative means of communication. However, there were a number of problems in the existing personal portals. For example, because the Web page as a personal portal was generated by the program located on the specific Web server which is managed by a system administrator, it was not always ideal for all users. To solve this kind of problems, we developed two Web Service functions, which are realized on the network by introducing the Destination Addressing Control System (DACS) Scheme. These two Web Service functions are as next. The first is the function to extract the data for each user from a database and display it on the Web browser. The second is the function to retrieve the data for each user from a document medium and display it on the Web browser. Through these Web Service functions, each user can easily create a customized personal portal that displays personal information. Then, the above two functions were extended to manage information not only for each user but also for each group of users and for all users, and the extended two functions were integrated as a DACS Web Service. By using the DACS Web Service, each user can create and customize the Web page as a personal portal for practical usage in an individual organization. However, when the use of it in a real network is assumed, it is difficult to make the Web page as the personal portal with a complicated function by the present web page as the personal portal using DACS Web Service Therefore, in this study, functional extension is performed. To be concrete, we realize the method of using the Common Gateway Interface (CGI) program opened to Internet by a user unit, and improve the present Web page as the personal portal using DACS Web Service by the method.

Evaluation by Implementation of the Policy-based Network Management System Called DACS System

As the work for managing a whole LAN effectively withoutlimited purposes, there are works of Policy-based networkmanagement (PBNM). The existing PBNM is defined in someorganizations including the Internet Engineering Task Force(IETF). However, it has structural problems. For example,communications sent from many clients concentrate on acommunication control mechanism called PEP (PolicyEnforcement Point). To improve the problems, we have beenstudying next generation PBNM called Destination AddressingControl System (DACS) Scheme. The DACS Scheme controlsthe whole LAN through communication control by the clientsoftware as PEP which locates on a client computer. We havebeen studied on the aspect of principle until now. In thisresearch, we implement a DACS system to realize a concept ofthe DACS Scheme, and show implement method and results offunctional experiments.

Principle of Virtual Use Method in Common Gateway Interface Program on the DACS Scheme

In the world of the Internet, Web Servers such as Apache and Internet Information Ser ver (IIS) were developed to exchange information among client computers having different Operation System. They have only the function of displaying static information such as HTML files and image files into the Web Browser. However, when the information i s updated, the administrator updates it by manual operation. In some cases, because it is necessary to update several places about the same information, the work load becomes high than it is assume and update error and update omission may occur. These prob lems were solved by use of a Common Gateway Interface (CGI) program such as a bulletin board system and a Blog system. However, these programs opened to Internet have often no user authentication mechanism and no access control mechanism. That is, they hav e the problem that user can access it freely only by getting the URL and inputting it to a Web Browser. Therefore, in this paper, we show a method to add the user authentication and access control mechanism for them. It is called virtual use method of CGI and is realized in the case of introducing the Destination Addressing Control System (DACS) Scheme, which is a kind of Policy Based Network Management Scheme (PBNM). As the result, this kind of the CGI program can be used in the organization with the abovetwo functions..

New user support in the university network with DACS scheme

Purpose – The purpose of this paper is to propose and examine the new user support in university network.Design/methodology/approach – The new user support is realized by use of DACS (Destination Addressing Control System) Scheme which manages a whole network system through communication control on a client computer. This DACS Scheme has been studied conventionally by authors.Findings – The new user support is more simplified than the normal user support in the network based on TCP/IP.Research limitations/implications – As a future research, the authors will implement the system for realizing DACS Scheme and apply that system to practical network. Then, the new user support proposed in this paper will be realized in practical network.Practical implications – The functions needed for the new user support are confirmed. Some functions was confirmed in the past research. The other function is confirmed in the section of experimental results.Originality/value – In the network introducing DACS Scheme, the sett...

Secure DACS Scheme

When customers with different membership and position use computers as in the university network systems, it often takes much time and efforts for them to cope with the change of the system management. This is because the requirements for the respective computer usage are different in the network and security policies. In this paper, a new destination addressing control system scheme (DACS Scheme) for the university network services is shown. The DACS Scheme performs the network services efficiently through the communication management of a client. As the characteristic of DACS Scheme, only the setup modification is required by a system administrator, when the configuration change is needed in the network server. Then, the setup modification is unnecessary by a customer, which shows a merit for both a system administrator and a customer. However, there is a problem to be solved. In existing DACS Scheme, it is assumed that DACS Client for controlling the communication must be implemented on all clients. If the client without DACS Client is connected to the network, each network server can be accessed from the client. Therefore, in this paper, secure DACS Scheme with the function to prevent the communication from the client without DACS Client is proposed and examined.
