IAM Federation Advanced

IAM Federation Advanced is the practice of managing identities across organizational and cloud boundaries using standardized protocols (SAML 2.0, OAuth2, OpenID Connect). A federated identity system enables users to authenticate once and gain access to resources across multiple organizations, cloud providers, and applications without entering credentials multiple times (single sign-on, or SSO). Practitioners design trust relationships, implement identity brokering, manage attribute provisioning, enforce access policies, and audit security. Systems must handle multi-cloud scenarios (AWS + Azure + GCP), comply with standards (SOC 2, FedRAMP, GDPR), and prevent common attacks (SAML reflection, OAuth token theft).
