Episode 77: Federation and SSO: SAML, OAuth, OpenID

Federated identity systems allow users to authenticate across multiple platforms using a single identity, often enabling Single Sign-On (SSO). In this episode, we explain how standards like SAML, OAuth 2.0, and OpenID Connect enable cross-domain authentication. You’ll learn the difference between authentication and authorization, how token exchanges work, and what security concerns arise with federated systems. These technologies reduce friction, improve user experience, and centralize control—but only when implemented correctly. CISSPs must understand how to secure identity federation for enterprise and cloud environments.
