Federated Identity Management Questions and Answers for Viva

Answer-1: Federated Identity Management (FIM) is a system that allows users to access multiple systems or services using a single set of credentials across different organizations.

Answer-2: It improves user convenience and security by enabling Single Sign-On (SSO) across multiple platforms and organizations.

Answer-3: It works by establishing trust between identity providers and service providers, allowing credentials from one domain to be accepted by another.

Answer-4: A system or organization that authenticates users and provides identity information to trusted partners.

Answer-5: SSO enables access to multiple services within one organization, while FIM extends this access across multiple organizations or domains.

Answer-6: Common protocols include SAML (Security Assertion Markup Language), OAuth, and OpenID Connect.

Answer-7: SAML is an XML-based open standard for exchanging authentication and authorization data between parties, commonly used in federated identity.

Answer-8: A group of organizations that have agreed to trust each other's authentication systems.

Answer-9: An IdP authenticates users and issues identity assertions to service providers.

Answer-10: A service provider relies on an identity provider to authenticate users and provide access to resources.

Answer-11: A digital assertion used to securely convey authentication and authorization data from an IdP to an SP.

Answer-12: OAuth allows a third-party application to access user resources without exposing the user's credentials by issuing access tokens.

Answer-13: An identity layer on top of OAuth 2.0 that enables authentication and secure identity information exchange.

Answer-14: It allows users from different organizations to securely access cloud services using their existing credentials.

Answer-15: Identity Provider (IdP), Service Provider (SP), security tokens, trust agreements, and protocols like SAML or OAuth.

Answer-16: Microsoft Azure AD B2B, Google Workspace SSO, and AWS Cognito with identity federation.

Answer-17: Reduced password fatigue, centralized access control, and seamless user experience across partner systems.

Answer-18: An established relationship between IdPs and SPs to securely share identity information.

Answer-19: A system or application that relies on an identity provider for user authentication.

Answer-20: The IdP authenticates the user and then securely transmits identity assertions to SPs.

Answer-21: Yes, it is designed to work across different organizations, platforms, and technologies.

Answer-22: It provides centralized auditing, consistent access policies, and ensures data access is well-documented.

Answer-23: It is the process of creating user accounts dynamically upon first login via federated identity.

Answer-24: It is the process of translating identity attributes from the IdP format to the SP format.

Answer-25: Risks include token interception, misconfiguration, or compromise of identity providers.

Answer-26: Users can use one set of credentials to access multiple services, reducing friction and improving productivity.

Answer-27: A process where a third party acts as a bridge between identity providers and service providers.

Answer-28: MFA adds extra layers of security by requiring additional verification methods beyond username and password.

Answer-29: Yes, modern mobile applications often integrate federated identity using OAuth or OpenID Connect.

Answer-30: SCIM (System for Cross-domain Identity Management) is a protocol for automating user provisioning in federated systems.

Answer-31: It?s an XML file that defines configuration settings and certificates used to establish trust between IdPs and SPs.

Answer-32: Federation allows cross-domain identity use, while delegation lets one party perform actions on behalf of another.

Answer-33: It reduces the number of stored passwords, centralizes authentication, and ensures consistent security policies.

Answer-34: The defined time after which a security token is no longer valid for authentication.

Answer-35: Yes, it allows seamless access to systems of merged organizations without migrating user credentials immediately.

Answer-36: It supplies specific identity attributes (claims) about a user to an SP for authorization.

Answer-37: They manage interactions between multiple IdPs and SPs, streamlining authentication flows.

Answer-38: A scenario where one identity provider relies on another to authenticate the user.

Answer-39: A setup where two tenants (organizations) in a cloud platform establish trust to share identity and access.

Answer-40: When an organization allows users from another external IdP to access its services securely.

Answer-41: By logging, auditing token exchanges, failed authentications, and reviewing access logs.

Answer-42: Federated SSO allows a user to authenticate once and access multiple applications across domains.

Answer-43: Challenges include trust management, standard compatibility, and ensuring consistent policy enforcement.

Answer-44: Through automated provisioning/deprovisioning, SCIM, and HR system integration.

Answer-45: It centralizes authentication, reducing helpdesk calls and manual user management.

Answer-46: Azure AD, Okta, Auth0, AWS Cognito, Google Identity, and Keycloak.

Answer-47: A method that requests higher authentication levels based on the sensitivity of the operation.

Answer-48: Passive relies on web browsers (e.g., SAML), while active is client-based and often uses WS-Trust.

Answer-49: Using social media credentials (Google, Facebook) for authentication to access third-party apps.

Answer-50: It allows partner users to access internal apps securely using their home organization?s credentials.
