Grid information service (GIS) is a core functional component of a grid that provides information about various resources and their status. Security underpins a GIS making secure access to a GIS an important issue. On the basis of our existing work on a GIS architecture, we further propose a security framework which leverages Shibboleth as the authentication infrastructure and combines PERMIS authorization technology. As a result, this security framework integrates the advantages of both Shibboleth cross-domain identity federation and PERMIS policy driven role based access control, thus presenting a new security model for secure access to a GIS.
