Networks ∙ Services ∙ People Bootstrapping using delegation model GÉANT Project Start-up Registration of all project participants with appropriate groups and authorisation data. Defined automated process using delegation model. To reduce IT overhead Includes features such as: invitations Enabling participant’s self-registration A delegation model to fit in the distributed management environment. IT invites Activity Leaders Activity Leaders invites Task Leaders Task Leaders invites Team Members The workflow is not only useful at the start of the project but also every time a new service or organisation is added to the central authorisation system. 8 Workflows … (Part 1)

Networks ∙ Services ∙ People Adding/Removing a project participant: Defines project participants’ provisioning and de-provisioning using delegation model. Preserves history when a project participant is de-provisioned. Change of group membership: The need arises: if user needs to be added or removed from a specific group or if user’s role has changed within project/home organisation etc. Change of Affiliation: Migrate the project participant’s profile to a new ID, affiliated to a new organisation. 10 Workflows … (Part 2)

Networks ∙ Services ∙ People Revalidating project participants To ensure that the project participant accounts are still active, defines automated and periodic revalidation. Managing exceptions Handles scenarios that deviate from “standard” practices e.g. a project participant might not hold the role of Task Leader (TL) but still be required to have all the same access as TLs. Defines the workflow, while taking care to provide the correct information as well e.g. list of TLs should not return ‘like TLs’ project participants. Auditing Defines verification of all the processes that are carried out at the central authorisation system to ensure their effectiveness and correctness at regular intervals. 12 Workflows … (Part 4)
