  1. An Integrated Framework for Identity and Access Management (IAM) RL”Bob” Morgan, U Wash., MACE Keith Hazelton, U Wisc., MACE Internet2 Spring Member Meeting May 3, 2005, Arlington, VA

  2. Session overview • Integration: IAM and applications (Keith) • Drivers & requirements (RL “Bob”) • From talking to doing (Keith again)

  3. I: From Construction to Integration • Construction • Raw materials into systems • Integration • Subsystems into whole systems • Multiple systems into ecosystems • We’re all moving from construction to integration • Let’s review state of middleware systems’ readiness for integration

  4. IAM: Generic Functions

  5. Reflect, Join, and Manage Credentials Enterprise Directory Systems of Record Stdnt Registry LDAP Reflect HR Join Other Manage Credentials

  6. Reflect, Join, and Manage Credentials • Collect bits of identity information in all the relevant IT systems • Use business logic to • Establish which records correspond to the same person • Maintain that identity join in the face of changes to data in collected systems • Assign a unique identifier for cross-system link

  7. Manage Credentials • When to assign, activate credentials • (as early as possible) • Who gets them? Applicants? Prospects? • “Guest” NetIDs (temporary, identity-less) • Reassignment (never; except…) • Please send me a feed… • Argument for WebISO

  8. Manage IAM Info and Provide it via run-time calls or provisioning Apps / Resources Enterprise Directory Central AuthN/WebISO AuthZ Systems of Record Log Reflect AuthN Provision Join Manage Creds AuthZ Manage Groups, Privs.,... Log Provide

  9. IAM functions & big pictures

  13. The User to Service Providerperspective

  14. The User to Service Providerperspective

  15. Next-up integration services • Message queuing (pub-sub, point-to-point) • Workflow (business process orchestration) • Policy info mgmt • Policy decision point • Service Oriented Architecture (SOA) as current buzz-word for the overall vision • The vision will outlast the name

  16. Middleware -- Application Integration • ERPs • SAKAI • uPortal • …

  17. IAM and Application Integration

  18. Inter-institutional integration • Virtual Organization (VOs) • Federations • League of Federations

  19. Part II: Drivers & Requirements

  20. Part III: Doing Integration: Service Oriented Architecture (SOA) • Goals • What software is deployed during an integration, where and how is it deployed? • What development is needed to accomplish an integration? • What is the development / deployment process? • How is the installation managed, maintained and expanded? • How do individual integrations work together to form an infrastructure?

  21. Service Oriented Architecture (SOA) Migration Strategy • Courtesy of Jim Phelps, Architect • U Wisconsin System Initiative • Common Systems Interoperability Architecture Working Group (CSIAWG)

  22. Migration Strategy - SOA • Organization - Change Management • Process - Business Process Analysis • Information - Enterprise Data Definitions • Infrastructure - Architecture and Technology • Vendors – Fill the Gaps

  23. Migration Strategy - SOA • Organization - Change Management • Culture shift from data to services • Staff Training and Support • New Expertise • Service Interface Designer(2) • Service Library Manager(2) • Integration Competency Centers(3)

  24. Integration Competency Center

  25. Migration Strategy - SOA • Organization - Change Management • Culture shift from data to services • Staff Training and Support • New Expertise • Service Interface Designer(2) • Service Library Manager(2) • Integration Competency Centers(3)

  26. Migration Strategy - SOA • Process - Business Process Analysis • Prioritization -Most Pain, Most Gain • Define/Document Business Processes • Look for optimization opportunities • Data needs (timeliness, availability, etc) • Use disruption to your advantage

  27. Migration Strategy - SOA • Information - Enterprise Data Identification • Let the Business Process Analysis drive the data definitions. • Don’t build a complete dictionary • Start with the most needed definitions • Build on standards

  28. Migration Strategy - SOA • Infrastructure - Architecture and Technology • Gap analysis - what pieces are missing • Architecture Analysis • Business Process Analysis and Enterprise Data Identification lead the efforts.

  29. Migration Strategy - SOA • We want to fix this business process. • It needs data and services to/from these systems. • We need these adaptors and data stores. • We need these technologies to deploy these services.

  30. Migration Strategy - SOA • Vendor - Evaluation to fill gaps • Business Process Analysis • Enterprise Data Identification • Data Definitions / schema development • Service Design • Technology Gaps

  31. Migration Strategy - SOA Always ask “is the request for data really a request for service”

  32. Roadmap to SOA UW System Level Business Application Level Campus Level

  33. Roadmap to SOA • Integration Competency Center ( ICC ) • Registry • Establish Governance • Development Standards • Common Tools UW System Level

  34. Roadmap to SOA • Analysis of Interfaces • Analysis of Business Processes • Reduction of Interfaces • Schema Definitions • Migration to Services Business Application Level

  35. Roadmap to SOA • ICC • Take advantage of disruption • Analysis of Business Processes • Reduction of Interfaces • Migration to Services Campus Level
