The Access Management Puzzle: Putting the Pieces Together Identity and Access Management at the UW Ian Taylor Manager of Security Middleware University of Washington

Context and Challenges  Large institution, diverse populations Three Campuses 43,000 students – Undergraduate, Graduate and Professional Extension Enrollment – 27,000 28,000 Faculty and Staff Two Medical Centers, Neighborhood Clinics, SCCA K-20 network  Result: over 512,000 UW NetIDs in use

Environment  Tension between central and decentralized governance Central IT (C&C), also much departmental computing  IT Strategic Plan: No ERP solution build on the legacy use best of breed niche solutions  IAM solutions: Open Source + Professionally-developed In-House

Foundation  UW NetID  Kerberos : MIT KDC deployed 1997  LDAP: Netscape Directory Server 1998 (switched to OpenLDAP in 2005)  Web ISO/SSO: pubcookie UW NetID "weblogin" service introduced on campus in 1999  Person Registry: 1999  Privilege Management: ASTRA v1 released 2003

Guiding Principles GGray’s Network Security Credo Open networks/Closed servers/Protected sessions Key elements of security architecture: Authn/Authz SSingle, ubiquitous identifier SSSO LLowest latency IIntegration VVisibility PPragmatism

Solution: Authentication

Solution: Authorization

Good outcomes  Roles Adapt to application needs Learn and limit  Authorization Management Central Distributed  Legacy Applications Publish Authorizations Manage Authorizations

Recent successes, upcoming challenges  UW Windows Infrastructure: course groups to AD  Treat Exchange population as a Subscription  Generate organizational groups by Budget  Push ASTRA Role occupants to Groups?  Web Service interfaces to LDAP directories  Greater federation via Shibboleth  Grouper  Global IdM  Levels of Assurance … and … of course …

Governance and Policy  IT and IM (OIM)  Data Management Committee  Minimum Data Security Standards  Roles Sub-committee
