Linking identity systems across organisations to enable seamless authentication and access.
Federation establishes trust between identity systems across organisational boundaries, enabling users from one organisation to access resources in another using their home credentials. Federation is used for B2B collaboration, cloud service access, and partner integrations. Standards like SAML and OIDC enable federation. When you log into a SaaS application using your company credentials, federation is at work—the application trusts your company's identity provider.
Why It Matters
The DSC Perspective:
Federation enables seamless B2B collaboration and cloud access. Understanding federation helps configure SSO integrations and evaluate identity architectures for partner access scenarios.
