Functional Concept - SSO

- Basics - Federated Identity
  • The concept of a centralized or linked electronic identity is known as federated identity. Federated identity systems handle several concerns:
    • Authentication
      • Deals with validating user crede ntials and establishing the identity of the user.
    • Authorization
      • Related to access restrictions (e.g., is the user allowed to access X resource?).
    • User attributes exchange
      • Deals with data sharing across different user management systems.
      • For instance, fields such as “real name” may be present in multiple systems.
    • User management
      • Related to the administration (creation, deletion, update) of user accounts.
