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.
