== Authorization == Wed, 1500-1630 Organizers: Steve Schwab and Ted Faber, USC/ISI GENI aggregates currently use signed XML credentials to make authorization decisions. At GEC10 we began a one year effort to evaluate ABAC assertions as a more flexible basis for GENI authorization. This meeting will seek agreement on a vocabulary for ABAC assertions and policies, and then surface outstanding issues and concerns or other work that must be addressed before the community can decide whether to adopt ABAC. We will also review the status of integrating ABAC in existing control frameworks and aggregates.
