Restricted Community Accounts
Portal-based access to high-performance computing resources for
communities is an emerging paradigm of allowing unprecented numbers of
users access to HPC systems. Examples of this include the
GridChem portal and the
TeraGrid
type 1 science gateways.
Processes launched by these portals still need to run in a Unix account on
the HPC resources they utilize. This raises a number of security concerns
as users of the portals are not vetted in the same manner as normal users
of the HPC resource. The portal is also an additional link in the trust
chain from the resource to the user that could be compromised, leading
in turn to the compromise of the HPC resource.
Our work is focused on developing tools that enable the HPC administrators
to sandbox the processes initiated by the portal. This allows the
administrator to limit the trust they place in the portal, mitigating their
risk in the even the portal is compromised.
An initial release of the tools is scheduled for early 2006. Targeted users include GridChem and TeraGrid.
