Explanation
Federated identity management allows organizations to link and reuse existing identity systems across different domains or services without rebuilding them. Standards like SAML, OAuth, or OpenID Connect enable a 'trust and delegate' model where each system continues to use its own authentication internally while accepting tokens or assertions from a central identity provider. This has the lowest upfront cost because existing systems do not need to be replaced or rewritten - only integration adapters are needed. Attestation (Option A) is a process for verifying system state, not an authentication integration approach. PKI (Option B) requires significant infrastructure deployment (CAs, certificate lifecycle management) and custom integration into each system - high upfront cost. Biometrics (Option C) requires hardware and middleware deployment across all endpoints - extremely high upfront cost and complexity.
