NDG Security

NERC DataGrid Security is both an architecture and implementation for federated identity management and access control. It was first developed for the NERC DataGrid and has been extended to support the Earth System Grid Federation under development to support secure access to the federated data archive for CMIP5 (The Coupled Model Intercomparison Project).
