The AliEn (Alice Environment) framework is an implementation of a Grid system developed in the Alice Collaboration.It is currently used to produce and analyze Monte-Carlo data at over 30 computing sites on four continents.The AliEn Web Portal was designed and built to serve as an entry point to AliEn and to encapsulate both a command and control interface and a complete monitoring system.The portal is built around common Open Source components with backend based on Web Services Resource Framework (WSRF).An easy and intuitive presentation layer allows the user to access information from multiple sources in a transparent and convenient way.Users can manipulate and check job provenance and access process monitoring information from a MonALISA repository.The presentation layer is separated from the content layer which is realized as several WS-Resources and Web Services serving one or more users or Virtual Organizations.The security and authentication of the portal is based on the Globus Grid Security infrastructure, WSRF::Lite and MyProxy online credentials repository.In this paper the architecture and functionality of the AliEn Web Portal is presented.
