  6. Components of IdMat Penn State • Kerberos, DCE, Active Directory • LDAP (eduPerson) • Cosign (WebAccess is local branding) • Shibboleth • Member of InCommon • “Access Account” - branding for Penn State identity (authn only available too), ~120K • “Short Term Access Accounts” (authn only available too), 178/9104 as of 11AM today • “Friends of Penn State” - branding for external identity, ~450K

  11. What attributes do we share with which service providers?

  12. Example 1 - WebAssign • Attributes Released • eduPersonPrincipalName (EPPN) • Physics course • Common name • Surname • Given name

  13. Example 2 - Turnitin • Attributes Released: • eduPersonPrincipalName • eduPersonPrimaryAffiliation • Given Name • Surname

  14. Example 3 – PHEAA(Pennsylvania Higher Education Assistance Agency) • Attributes Released: • eduPersonScopedAffiliation • eduPersonAffiliation • Given Name • Surname • Date of Birth • Social Security Number

  15. So….how did we decide what attributes can be released to an external service provider?

  16. Using Example 1 - WebAssign • Course information • students pay directly for access to physics content • Existing policies related to FERPA and student records (AD-11) • “The following is a list of directory items that may be made available to the public regarding students of the University without their prior consent and is considered part of the public record of their attendance: “ • Confidentiality hold

  17. Using Example 3 - PHEAA • Current policies define what attributes, or combination of attributes, constitute a FERPA protected record • AD-11 - University policy on confidentiality of student records • Social Security Number • AD-19 - Use of Penn State Identification and Social Security Number • Requires special permission from Chief Privacy Officer

  18. Summary of Process for Distributing Attributes • Identify which attributes are “required” by service provider to complete transaction • Work with appropriate people to verify attributes can be shared • University affiliate, IdM administrators, Chief Privacy Officer, Data Stewards • Shibboleth Identity provider admin creates attribute release policy

  19. Points to Ponder • Confidentiality hold • Leverage well established business rules • Personal management of attribute release (SHARPE) • Third party policy • Audits of TP security practices • Addendums to contracts

  20. The On-Going Challenge • Good tools exist but that’s not enough • The only thing standing between these principles & practices and making a big difference with them is: • developing the institutional will to constantly improve IdM • creating a groundswell of epiphanies across the university
