Participation in the InCommon Federation (“Federation”) enables a federation participating organization ("Participant") to use Shibboleth identity attribute sharing technologies to manage access to on-line resources that can be made available to the InCommon community. One goal of the Federation is to develop, over time, community standards for such cooperating organizations to ensure that shared attribute assertions are sufficiently robust and trustworthy to manage access to important protected resources. As the community of trust evolves, the Federation expects that participants eventually should be able to trust each other's identity management systems and resource access management systems as they trust their own.
A fundamental expectation of Participants is that they provide authoritative and accurate attribute assertions to other Participants, and that Participants receiving an attribute assertion protect it and respect privacy constraints placed on it by the Federation or the source of that information. In furtherance of this goal, InCommon requires that each Participant make available to other Participants certain basic information about any identity management system, including the identity attributes that are supported, or resource access management system registered for use within the Federation.
Two criteria for trustworthy attribute assertions by Identity Providers are: (1) that the identity management system fall under the purview of the organization’s executive or business management, and (2) the system for issuing end-user credentials (e.g., PKI certificates, userids/passwords, Kerberos principals, etc.) specifically have in place appropriate risk management measures (e.g., authentication and authorization standards, security practices, risk assessment, change management controls, audit trails, etc.).
InCommon expects that Service Providers, who receive attribute assertions from another Participant, respect the other Participant's policies, rules, and standards regarding the protection and use of that data. Furthermore, such information should be used only for the purposes for which it was provided. InCommon strongly discourages the sharing of that data with third parties, or aggregation of it for marketing purposes without the explicit permission of the identity information providing Participant.
InCommon requires Participants to make available to all other Participants answers to the questions below.

2. Identity Provider Information
The most critical responsibility that an IdentityProvider Participant has to the Federation is to provide trustworthy and accurate identity assertions. It is important for a Service Provider to know how your electronic identity credentials are issued and how reliable the information associated with a given credential (or person) is.
2.1 If you are an Identity Provider, how do you define the set of people who are eligible to receive an electronic identity? If exceptions to this definition are allowed, who must approve such an exception?
Anyone who is a community member, i.e. has an active record in either the human resource or registrar database, as well as all applicants and a variety of miscellaneous affiliated or unaffiliated guests.
2.2 “Member of Community” is an assertion that might be offered to enable access to resources made available to individuals who participate in the primary mission of the university or organization. For example, this assertion might apply to anyone whose affiliation is “current student, faculty, or staff.”
What subset of persons registered in your identity management system would you identify as a “Member of Community” in Shibboleth identity assertions to other InCommon Participants?
Member of Community is defined enrolled students, faculty, adjunct faculty, staff, emeriti and retirees. We also maintain accounts for alumni for a period of two years after graduation.
Electronic Identity Credentials
2.3 Please describe in general terms the administrative process used to establish an electronic identity that results in a record for that person being created in your electronic identity database? Please identify the office(s) of record for this purpose. For example, “Registrar’s Office for students; HR for faculty and staff.”
The creation of an electronic identity (Bronco NetID) is initiated when the Office of Human Resources enters an employee record in the HR information system, or the University Registrar enters a student record in the student information system.
2.4 What technologies are used for your electronic identity credentials (e.g., Kerberos, userID/password, PKI, ...) that are relevant to Federation activities? If more than one type of electronic credential is issued, how is it determined who receives which type? If multiple credentials are linked, how is this managed (e.g., anyone with a Kerberos credential also can acquire a PKI credential) and recorded?
LDAP for storage of electronic identities and MIT Kerberos for passwords associated with identities. Both LDAP and Kerberos are used by an Identity Provider to validate passwords supplied by users over a TLS-protected Web session.
2.5 If your electronic identity credentials require the use of a secret password or PIN, and there are circumstances in which that secret would be transmitted across a network without being protected by encryption (i.e., “clear text passwords” are used when accessing campus services), please identify who in your organization can discuss with any other Participant concerns that this might raise for them:
All services requiring authentication with Bronco NetID and password are required to use SSL. For questions, see 1.3.
2.6 If you support a “single sign-on” (SSO) or similar campus-wide system to allow a single user authentication action to serve multiple applications, and you will make use of this to authenticate people for InCommon Service Providers, please describe the key security aspects of your SSO system including whether session timeouts are enforced by the system, whether user-initiated session termination is supported, and how use with “public access sites” is protected.
Shibboleth uses LDAP and Kerberos for authentication and does not currently interface with our on-campus single-signon system.
2.7 Are your primary electronic identifiers for people, such as “net ID,” eduPersonPrincipalName, or eduPersonTargetedID considered to be unique for all time to the individual to whom they are assigned? If not, what is your policy for re-assignment and is there a hiatus between such reuse?
Bronco NetIDs are unique, are never changed once created, and are not reused.
Electronic Identity Database
2.8 How is information in your electronic identity database acquired and updated? Are specific offices designated by your administration to perform this function? Are individuals allowed to update their own information on-line?
The source information is maintained in the administrative systems of record by human resources and the registraar. Updates to our Enterprise LDAP directory from these systems of record are performed regularly several times per day.
Individuals can update limited aspects of their records in those systems, e.g. people may update some of their addresses, but most updates are not self-service.
2.9 What information in this database is considered “public information” and would be provided to any interested party?
Public information is limited to email address, on-campus telephone numbers, and general campus affiliation data.
Uses of Your Electronic Identity Credential System
2.10 Please identify typical classes of applications for which your electronic identity credentials are used within your own organization.
Email, elearning, network access and registration, file servers, public labs, portal, University libraries, interactive shell access, and various web-based services.
Attributes are the information data elements in an attribute assertion you might make to another Federation participant concerning the identity of a person in your identity management system.
2.11 Would you consider your attribute assertions to be reliable enough to:
[ X ] control access to on-line information databases licensed to your organization?
[ X ] be used to purchase goods or services for your organization?
[ X ] enable access to personal information such as student loan status?
Federation Participants must respect the legal and organizational privacy constraints on attribute information provided by other Participants and use it only for its intended purposes.
2.12 - What restrictions do you place on the use of attribute information that you might provide to other Federation participants?
The release of attribute information to federation participants will be negotiated on a case-by-case basis.
Data shared with a federation participant is considered private and confidential. Western Michigan University's express written consent is required prior to the release of data to a third party.
2.13 - What policies govern the use of attribute information that you might release to other Federation participants? For example, is some information subject to FERPA or HIPAA restrictions?
Information released may be subject to FERPA and HIPAA restrictions.
3. Service Provider Information
Service Providers are trusted to ask for only the information necessary to make an appropriate access control decision, and to not misuse information provided to them by Identity Providers. Service Providers must describe the basis on which access to resources is managed and their practices with respect to attribute information they receive from other Participants.
3.1 What attribute information about an individual do you require in order to manage access to resources you make available to other Participants? Describe separately for each service ProviderID that you have registered.
3.2 What use do you make of attribute information that you receive in addition to basic access control decisions? For example, do you aggregate session access records or records of specific information accessed based on attribute information, or make attribute information available to partner organizations, etc.?
3.3 What human and technical controls are in place on access to and use of attribute information that might refer to only one specific person (i.e., personally identifiable information)? For example, is this information encrypted?
3.4 Describe the human and technical controls that are in place on the management of super-user and other privileged accounts that might have the authority to grant access to personally identifiable information?
3.5 If personally identifiable information is compromised, what actions do you take to notify potentially affected individuals?
4. Other Information
4.1 Technical Standards, Versions and Interoperability
Identify the version of Internet2 Shibboleth code release that you are using or, if not using the standard Shibboleth code, what version(s) of the SAML and SOAP and any other relevant standards you have implemented for this purpose.
Western Michigan University operates Shibboleth Identity Provider 2.3.8.
4.2 Other Considerations
Are there any other considerations or information that you wish to make known to other Federation participants with whom you might interoperate? For example, are there concerns about the use of clear text passwords or responsibilities in case of a security breach involving identity information you may have provided?
Any provider experiencing a security breach must notify firstname.lastname@example.org as soon as the breach is discovered. Information provided must include the scope of the breach, the nature of the information revealed and any other relevant information. Similarly, any Federation member concerned about security issues involving WMU should contact the WMU Security team at the above email address.
