Abstract

Web is playing a more and more important role in our daily life. Large volume of personal and business communications are taking place via Web everyday. Due to its importance and its vulnerabilities from the early design, the Web has become a preferred target of attacks. After discussing the causes and effects of vulnerabilities, we then present that the current access control system of the web is the root cause for these problems. As a part of the efforts to develop a fine-grained access control system in a Web application, we focus on the dynamic scoping for browser based access control. Instead of using static scope to isolate the client code from the trusted web application, dynamic scoping is utilized to identify different patties in a Web page. Such an improvement will allow the client and trusted web application share common libraries, while still get executed at different trust levels.
