Episode 17 — Leverage Single Sign-On and Federation for Usability
Single Sign-On (SSO) and federation reduce password sprawl while improving control, and exam items often test whether you can match the right protocol and trust model to a scenario. We define SSO within a domain versus cross-domain federation, outline roles (identity provider, service provider, relying party), and compare common protocols such as SAML, OAuth 2.0, and OpenID Connect at a conceptual level. You’ll learn how assertions, tokens, and claims convey identity and authorization context, how audience and expiration protect tokens, and where step-up authentication applies. We also discuss service accounts and non-interactive flows, tying everything back to least privilege and accountability.
The second paragraph focuses on practical designs and failure modes. We examine mapping groups and attributes to application roles, enforcing MFA at the identity provider, and using conditional access to evaluate device state, location, and risk signals. We cover token lifetimes, refresh strategies, and revocation considerations, plus secure logout and session termination across multiple apps. Troubleshooting guidance addresses clock skew, misconfigured entity IDs, non-unique identifiers, and over-permissive scopes in delegated access. Realistic examples show how to integrate legacy apps via password vaulting or header-based adapters while planning a migration path. The goal is confidence selecting the simplest trust that delivers security, auditability, and a positive user experience without creating brittle dependencies.
