    • Agree on Terminology
    • Current Landscape
    • SSO Utopia
    • Application – Framework View
    • Future State
    • Roadmap
  • 3. Why listen to this @jfbauer guy on SSO?
    • SSO Related Speaking Engagements
    • Nov. 2008 CA World, Identity and Access Management
    • Sept. 2008 Oracle OpenWorld, Identity and Access Management
    • Aug. 2008, CA IAM Conference, Houston, TX
    • July 2008, Medical Mutual IAM Conference, Cleveland, OH
    • Nov. 2007, Gartner Identity and Access Management Conference, Los Angeles, CA
    • Nov. 2007, Oracle OpenWorld, Online Real-time Fraud Detection
    • Aug. 2007, Oracle NEO Enterprise Architecture Quarterly
    • June 2006, NACHA Authentication conference, Reston, VA
  • 4. Agree on Terminology Single Sign-On? LDAP vs. Active Directory? Authentication vs. Authorization? Build vs. Buy? Vendor Solutions? TAM vs. SiteMinder vs. OAM? Security = Inverse of Convenience? Directory of Record? How/When to “Integrate?” Roadmap? Entitlements? IAM?
  • 5. Agree on Terminology
    • First step, establish definitions for terminology so we can all speak the same language
  • 6. Agree on Terminology
    • Single Sign-On = Ability for a single individual to use one single set of credentials (ex. user name + password) to access multiple applications they use with applications
    • Authentication = Simply an individual providing credentials to prove who they are
      • I’m really Bob, not Mary
  • 7. Agree on Terminology
    • Authorization = Simply verifying if an authenticated individual has been granted access to an application
      • I’m Bob and I can access Application X
    • Audit = Recording in a log file what just occurred
      • Bob successfully accessed Application X login page on 7//7/2010 at 9:01am EST
  • 8. Agree on Terminology
    • Entitlements = Now that an individual has been authenticated and is authorized to access an application what can and can’t they do/see within that application
      • I’m Bob, I can access Application X and within Application X I can view planning data and reports but I can’t change anything
  • 9. Agree on Terminology
    • LDAP = “Lightweight Directory Access Protocol is an application protocol for querying and modifying data using directory services running over TCP/IP”*
    • Directory = “is a set of objects with attributes organized in a logical and hierarchical manner.”*
    *Source = http://en.wikipedia.org/wiki/LDAP
  • 10. Agree on Terminology
    • Active Directory = “is a technology created by Microsoft that provides a variety of network services, including: … LDAP”*
    • Kerberos = “a computer network authentication protocol, which allows nodes communicating over a non-secure network to prove their identity to one another in a secure manner”** or one way to authenticate stuff
    *Source = http://en.wikipedia.org/wiki/Active_Directory **Source = http://en.wikipedia.org/wiki/Kerberos_(protocol)
  • 11. Agree on Terminology
    • IAM = “Identity and Access Management” or the IT/Security industry discipline that encompasses all this stuff (analogous to PMO for projects or ITIL for systems management, etc.)
  • 12. Current Landscape
    • Second step, agree on how this are currently done so we all are working from the same baseline understanding
  • 13. Current Landscape
    • Everyone solves the 3 A’s within their own solution domain
      • 3 A’s = “Authentication, Authorization and Auditing”
      • Each project has to invest time/energy/$$$/resources to solve the same AAA problems over, and over, and over
      • Post project, per application AAA workflows provide on going support costs
  • 14. Current Landscape
    • Um, err, business case here???
      • International Data Group reports that an average user in a 10,000-employee company has 14 separate passwords.
      • Forrester, “Password problems and resets generally constitute between 25% and 40% of total help desk incidents”*
    *Source = Twenty-three Best Practices For the Customer Service Center, Chip Gliedman, Forrester, 10/11/2005
  • 15. Current Landscape
    • Long story short … if an organization continues to grow without an SSO strategy + solution, the costs associated with managing user application access (AAA) will proportionally increase
  • 16. SSO Utopia
    • Common service for external SSO
    • Common service for internal SSO
    • Self Service credential reset
    • Standard SSO integration path for all project solutions/applications
    • TOC for IAM reduced across the enterprise
    • Raises for everyone in IT
  • 17. Application – Framework View
    • More realistically:
  • 18. Future State Approach Pros Cons In-House Developed Solution
    • Control over entire feature set
    • Lack of vendor dependencies
    • Deep internal SME over solution
    • Will take longer
    • Will require a larger team to execute.
    • Longer delay to benefiting from ROI
    • Lack of inherent competency in this space.
    • Resource attrition takes away irreplaceable knowledge thus reducing initial approach value
    Purchase Vendor Framework
    • Already mature product options in the marketplace
    • Top tier vendors investing in this space (CA, Oracle, IBM, etc.)
    • Faster realization of outlined benefits
    • Leverage vendor expertise to augment internal resources as needed
    • Will incur licensing and support cost from selected vendor.
    • Will involve normal vendor product lifecycle management challenges (version upgrades, product road maps, custom feature sets)
  • 19. Roadmap
    • Agree on definitions
    • Agree on SSO utopia future state
    • Agree on strategic Auth and Az stores
      • Example: LDAP for all external users?
      • Example: AD for internal/employees?
    • Agree on initial SSO integration approach
      • New project designs w/SSO after X date
      • or retrofit N existing applications
      • or “Major project Y and then …”
      • or some other criteria???
  • 20. Roadmap
    • Evaluate/RFI/RFP vendor landscape
      • Short list
        • Example: CA, Oracle and IBM
        • Consider Gartner “magic quadrant” and existing vendor relationships
    • Vendor POC including “integration service” modeling
      • Legacy/Project integration criteria
      • FTE/staffing to support
    • Production deployment
    • Integrations!
