the identity management paradox
The Identity Management Paradox
  • Many enterprises have deployed centralized identity management throughout their enterprises
    • Though users still have multiple passwords and user ID’s!
  • If I’m an employee, I have many more external passwords than internal
  • If I’m a partner / customer employee or a consumer, I have many id’s and passwords at many sites
  • Net Result – Single sign-on is not achieved in any circumstance!
  • Fidelity Study* shows enterprise users have on average 20 accounts!
    • 5 internal and 15 external
    • Even after enterprises have deployed Identity Management!

*Presented in the Digital ID World Conference 2003

identity management components
Identity Management Components
  • Web Access Management
  • Identity Management / Provisioning
  • Virtual Directories
  • Federated Identity Management
web access management
Web Access Management
  • Web Access Management
    • Centralized policy server with agents protecting web-sites
    • Agents authenticate users against central policy server
    • Agents share session tokens for single sign-on

identity management provisioning
Identity Management / Provisioning
  • Ensuring application stores have user information before users log on
  • Enable “reduced sign-on” (RSO)
  • Extend to mainframe and client-server applications
virtual directories
Virtual Directories
  • Aggregate view of information based on disparate stores
    • Typically an LDAP view
    • Connectors / adapters to all data sources / sinks
  • Can be used to enable provisioning
  • Provide password synchronization
federated identity management10
Federated Identity Management
  • The evolution of identity and access management (IAM)
    • Agreements, standards and technologies that make identity and entitlements portable across autonomous domains.
  • Seamless access to

independent web-resources without a centralized repository

  • Standards based
    • Liberty Alliance
    • SAML
    • WS-Federation / Trust

why federated identity standards
Why Federated Identity Standards
  • Federation is all about communication between independent enterprises / organizations
  • Proprietary approaches have failed in the past
    • Microsoft Passport
    • Proprietary WAM solutions
  • Interoperability is of paramount importance
    • Technical Interoperability
    • Business and Process Interoperability
  • Open reviews and non-discriminatory IP policy drives security
standards in federated identity
Standards in Federated Identity

“I love standards – there are so many to choose from!”

  • SAML from OASIS SSTC
    • Oldest, most prevalent standard
    • Foundational mechanisms in SAML 1.1 and 1.0 (Liberty based on SAML 1.1)
    • SAML 2.0 has more features (e.g. global logout)
  • Liberty Alliance a body of over 150 companies
    • Many technology users on management board
  • Microsoft and IBM: behind WS-Federation
    • Microsoft incorporating into Windows 2003 server R2 patch release
key concepts and terminology universal to the standards
Key Concepts and Terminology - Universal to the “Standards”
  • Identity
  • Circle of Trust / Trusted Sites
    • Principal Identity
    • Identity Provider (IdP)
    • Service Provider (SP)
    • Liberty Enabled Clients or Proxies (LECP)
  • Federation and De-federation – initial linkage or final disconnect
  • Single Sign-On and Authentication
  • Single Logout / Global Logout
  • Network Identity / Federated Identity – Federated Network
  • Pseudonyms & Anonymity (Opaque Identifiers)
  • Authentication Assertions
federated identity management value proposition
Federated Identity Management – Value Proposition
  • Each domain manages attributes and credentials for their own user community.
    • Deployments focus on reduced administrative costs and improved user convenience, but there is more value to be gained.
  • Administrative authorities can react faster to status changes of their own employees.
    • Instead of relying on delegated administration or synchronization.
  • User Attributes are shared on a limited basis or specific purposes
    • Improving implied and effective privacy.
  • Federation supports and simplifies compliance initiatives.
  • Federation separates Session Management from the User Management and Provisioning infrastructure.
federated identity management typical scenario
Federated Identity Management – Typical Scenario
  • A large organization must provide access to internal applications for thousands of partners (each having thousands of potential users).
  • External users are co-mingled with employees in a corporate directory.
  • A combination of delegated administration and synchronization is used to manage these entries.
    • Often this is coupled with other processes to maintain the directory.
  • Identity Federation provides relief for this situation.

federated identity management enhancing privacy
Federated Identity Management – Enhancing Privacy

Who are you?

  • Federation reduces (if not eliminates) the capture and storage of identity data across domains.
    • Fewer organizations hold user information
    • Easily accommodate regional, cultural or legal differences in privacy regulations
  • Make users anonymous where appropriate.
    • A partner may only need to know the originating domain (and assume that domains user authentication) not specific information about the specific user.
  • Implement pseudonyms for audit tracking.
    • Home domain holds mapping for user to pseudonym.
  • Permission based attribute sharing.
    • Puts user in control of attributes being shared
    • Application can prompt user to release information
      • A user can control what information is released and when
  • Effectively ties into “Emerging User Centric Business Model”.
  • Simplify infrastructure for global enterprises
    • Privacy concerns delaying or stopping deployments due to regional issues
    • Federation provides a viable alternative
      • Reduced need to consolidate all attributes in a single location
      • Provides opt-in model
federated identity management improves security
Federated Identity Management – Improves Security

Reduce Burden on Security Administrators

  • Enable them to focus on internal users
    • Let partners / customers manage their own users
  • Reduce or eliminate the need to mix external identities in internal user repositories
    • Best practices say that you should separate internal users from other user communities.
    • This reduces your exposure to vulnerability and outside attack.
federated identity management improves security21
Federated Identity Management – Improves Security

Federation Provides more Access Control Options

  • Access control checking at originating site, destination site, or both
  • Ability to map external users to internal groups, roles or local system records
  • Eliminate the need to provision credentials and access control to partner systems.
  • Consistently enforce policy throughout a transaction chain.
  • More granular access control than most VPN connection options.

Federated Identity Management – Improves Security

Fewer Passwords for Users to Remember

  • Passwords are weak authenticators
  • Users can rely on fewer, yet stronger authentication credentials
  • Enterprises have more flexibility to implement stronger authentication where appropriate.
  • Enterprises can convey that stronger authentication in a federated network.
federated identity management demonstrates compliance
Federated Identity Management – Demonstrates Compliance

Holding Authoritative Parties Accountable

  • Federation places user registration and credential management with the most responsible party.
  • Federation reduces duplicate administrative steps which could introduce errors or inconsistencies.
  • Policies and procedures for user management can be included in the ‘Federation Agreement” to be clear about responsibility and liability

Makes it Easier to Audit the Environment

  • Streamline the audit process to clearly separate internal employees from external parties and easily demonstrate the environment is properly partitioned.
  • Reduces the amount of data that is collected and stored thus relieving administrative burdens as well as custodial responsibility (liability)
  • Reduces compliance interdependencies between partners.
federated identity management simplifies idm infrastructure
Federated Identity Management – Simplifies IdM Infrastructure

Separates User Deployment from User Management

  • Expands effective user session management quickly to all resources (internal and external).
  • Allows for quick adoption of various standards depending on choices of all participants, without major management systems upgrades.
  • Provides simplified method to expose or integrate web resources (web services, applications, partners, customers) to user communities.
  • Delivers total platform integration flexibility (Open systems, Windows, Mainframe).
web services security impact of federated identity management
Web Services Security – Impact of Federated Identity Management
  • Web-services typically extend key enterprise resources
    • Not having to trust apps simplifies development and adds flexibility
    • Web-services may also be exposed to partners
  • Usual security concerns
    • Authentication, privacy, integrity, non-repudiation
  • But at at-least two levels:
    • Between a web-service and an app using it
    • Between the web-service and the end-user using the app
  • Lack direct user-sessions
    • Proprietary technology works within one identity domain
    • Standards solve the problem effectively
identity based web services
Identity Based Web Services
  • Effectively provides security between the web-service, consuming applications and the end-user
  • Security Mechanisms
    • Service discovery
    • Service invocation
    • Interaction with users
  • Standard service interfaces
    • Common services (e.g. user profile information)
