Description
The User Forum poster session has always been on of the most lively and vibrant parts of the event. We expect this year to be no exception. 40 posters have been accepted and will be presented during the two relevant sessions, on Monday and Wednesday afternoon, in parallel with the demonstration sessions. This year the poster session offers a mixture of scientific and technical presentations on a wide variety of subjects: Grid security, distributed programming development tools, infrastructure operations and recent progress of DCI exploitation by traditional as well as nascent user communities. The attendees will have the opportunity to closely interact with the poster presenters, get informed about their recent activities, exchange ideas and potentially establish new collaborations. They will also have the chance to vote for the best poster in display. The winner will be announced during the User Forum closing plenary on Thursday morning.

The EGEE Grid Security Vulnerability Group was formed "to incrementally make the Grid more secure and thus provide better availability and sustainability of the deployed infrastructure". The aim is to eliminate vulnerabilities from the Grid and prevent new ones from being introduced, thus reducing the risk of security incidents. This poster alerts users and developers to both the activities of...

The use of X.509 certificates gives flexibility in authentication and authorisation on the grid. The associated key is usually stored on the user's computer. While this is good practice from a security standpoint, managing keys and certificates is far from trivial. jGridstart attempts to bridge this gap by providing a friendly user-interface to guide the user in requesting, renewing, and...

MEG allows users to logon to a grid-resource using any SSH-enabled client, so long as they have uploaded a credential to a MyProxy server. MEG accepts the username and password to the credential from the SSH client and retrieves the proxy on behalf of the user, and the uses the proxy to determine if the login can proceed. Resource providers benefit too, as only grid-based authentication...
