FederationInterfederation

Productional interfederations
  • Interfederation with eduGAIN. Adoption just started, see the Interfederation documentation

Policy

FederationOrganization

Contractual structure
  • SWITCHaai is a service provided by SWITCH to the SWITCHaai Participants.
  • SWITCH Community For organizations which belong to the SWITCH Community, the legal basis are the 'SWITCHaai Service Description' together with the 'Service Regulations for Services by SWITCH' to which they are bound.
  • Federation Partners sign a SWITCHaai Federation Partner agreement with SWITCH.
Organizational structure

The SWITCHaai Advisory Committee meets once or twice a year to discuss more strategic matters. The SWITCHaai Community Group gets consulted on more operational matters.

Responsibilities of the operator

see SWITCHaai Service Description

FederationCampusIdentityManagement

Personal accounts

No explicit requirement for accounts to be personal. However, data privacy law requires that personal data has to be correct and up-to-date.
It would be in contradiction if an account is shared by multiple persons and the attributes for this account would indicate a single person.

Initial authentication

Best current practice. Established processes to provision accounts for staff and students.

On-line authentication

Best current practice, according to established local rules.

Attribute quality

Established processes to guarantee up-to-date data, according to general data protection principles.

Audits

FederationPrivacy

Purpose of processing personal data

See 9.6 of the SWITCHaai Service Description

Relevance of attributes
  • Within the Resource Registry, the SP admin configures the attribute requirements for the resource.
  • The Resource Registration Authority of the correspronding SWITCHaai Participant reviews and approves it.
  • Admins using Shibboleth 2.x IdP can influence the default attribute release through the Resource Registry and retrieve the customized attribute filter file automatically from the Resource Registry.
User consent

SWITCH provides uApprove as a method to implement user consent at the IdP.

Informed consent

SWITCH provides uApprove as a method to implement informed consent.

Attribute release to 3rd countries

According to the Swiss federal data protection regulation.

and participants

As defined in paragraph 9.5 of the SWITCHaai Service Description and paragraph 7 of Service Regulation for services by SWITCH.

FederationIncidentHandling

Log files

IdPs and SPs keep log files which allow to track back the identity of the person autenticating at the IdP.

Investigation of abuse

For investigation of abuse, the SP provides relevant info from itsl logs to the IdP.

See the statement on Digital Identities, SWITCHaai and OpenID

Implementations

04/2012: All IdPs use Shibboleth 2.x and 98% of SPs support SAML2, most of them using Shibboleth 2.x

Metadata

FederationSchema

Name and version of the schema swissEduPerson
Schemas adopted person, orgPerson, inetOrgPerson, eduPerson
Use of other attributes On bilateral basis, IdPs and SPs may agree on any attributes they like.
Mandatory attributes

The SWITCHaai Attribute Specification linked above has the concept of attribute implementation status, which every IdP in the federation must populate for each end user. The core attributes are:

  • swissEduPersonUniqueID
  • eduPersonTargetedID
  • sn
  • givenName
  • mail
  • swissEduPersonHomeOrganization
  • swissEduPersonHomeOrganizationType
  • eduPersonAffiliation
The major unique identifier

Currently, swissEduPersonUniqueID is the predominant unique ID. The intention is to start using eduPersonTargetedID as attribute alongside the SAML2 persistent NameID once all IdPs are using Shibboleth 2.

swissEduPersonUniqueID reassignment policy

swissEduPersonUniqueID MUST NOT be reassigned

Preferred syntax for ePTID/PersistentID on SAML2

For inter-operability reasons both in parallel: SAML2 persistent NameID in the subject element as well as ePTID attribute value in the attribute statement

FederationCa

CAs accepted

Browser-facing services can use any certificate. Federation security is based on certificates published in the signed metadata file, no validation based on CAs.

FederationTools

Tools used in the operations of the federation
  • Virtual Home Organization (VHO) enables certain users access via Shibboleth to a single resource, even they have no account at a federation member.
  • The Resource Registry to decentralize the maintenance of the federation metadata. It is the sourcce for the federation metadata file and it provides IdPs with pre-configred arp.site.xml files.
  • SWITCH-DS/WAYF, a SAML Discovery Service written in PHP. It also supports an easy embedding of the Discovery Service into Service Providers.
  • Guest Login Identity Provider. The Guest Login service allows users to create an account with self-registration. In contrast to the Virtual Home Organization where a VHO group administrator creates and manages the accounts. Any user with a valid email address can create and manage his own account. However, this account can only be used to access a very limited number of services in the SWITCHaai Federation. These services must explicitly allow guest users by means of configuration. Therefore, the Guest Login Identity Provider is not part of any federation.
Tools used by IdPs and SPs
  • uApprove, a plug-in for Shibboleth 2 IdPs, to ask the users for consent before releasing the attributes to a Service Provider. uApprove can also request acceptance of a 'Terms of use' statement. This tool was formerly named ArpViewer.
  • Group Management Tool (GMT) allowing a resource administrator to easily configure the access to his resource on an individual basis.
