With the growth of the World Wide Web, it has become more and more important to find implementation models tailored especially for Web applications. Unlike traditional applications, Web portals are required to be constantly up to date and are therefore often subject to changes at runtime. Consequently Web application frameworks have been developed that allow the construction and manipulation of Web pages consisting of pre-built components as an alternative to re-programming. The capability of such systems rises with the number of available components. Hence it is advisable to facilitate their deployment and exchange with a supporting architecture. The achieved increased use of third party components also results in higher risks for the provider of the portal. Especially the resource access by the contained code poses a potential threat and lowers the acceptance for foreign components. This paper proposes a robust architecture for the installation, administration and exchange of portal components and addresses the need for protection against malicious code.
