DACS方案中公共网关接口程序的虚用法原理
Principle of Virtual Use Method in Common Gateway Interface Program on the DACS Scheme
摘要：
在互联网的世界中，开发了诸如Apache和互联网信息服务器（IIS）的Web服务器，以在具有不同操作系统的客户端计算机之间交换信息。它们只具有将静态信息（如HTML文件和图像文件）显示到Web浏览器中的功能。但是，当更新信息时，管理员通过手动操作来更新信息。在某些情况下，因为需要更新关于相同信息的多个位置，所以工作负荷变得比假设的高，并且可能发生更新错误和更新遗漏。这些问题通过使用诸如公告板系统和博客系统的公共网关接口（CGI）程序来解决。然而，这些向Internet开放的程序往往没有用户认证机制，也没有访问控制机制。也就是说，他们有这样的问题，用户只能通过获取URL并将其输入到Web浏览器来自由访问它。因此，本文提出了一种为它们添加用户认证和访问控制机制的方法。它是在引入目的地址控制系统（DACS）方案的情况下实现的，DACS方案是一种基于策略的网络管理方案（PBNM）。结果表明，这种CGI程序可以用于具有上述两种功能的组织。
英文摘要：
In the world of the Internet, Web Servers such as Apache and Internet Information Server (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 is 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 problems 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 have 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 above two functions.
