Which term refers to linking electronic identities and attributes across multiple distinct identity management systems?

• A. Web Of Trust.
• B. Automation/Orchestration.
• C. Federation.
• D. Natural Language Processing.

Answer: (C)

Federation enables linking electronic identities and attributes across multiple, distinct identity management systems, creating a trusted bridge so a user authenticated in one domain can access resources in another without re-authenticating. It works by establishing a trust relationship between identity providers and service providers and exchanging assertions about who the user is and what they can do. Common protocols and standards used include SAML, OpenID Connect, and OAuth, which carry the user’s authentication status and selected attributes across domains. This is why federation is the best fit: it directly describes cross-domain identity linkage and trust, unlike a Web of Trust (peer-to-peer cryptographic trust within a network), Automation/Orchestration (which automates IT processes), or Natural Language Processing (which analyzes human language).
