Which statement best describes the cross-system identity requirement that IDMS enforces?

• A. The same identity must be verified and used across all integrated systems
• B. Identities are stored separately in each system without verification
• C. Identity verification is optional
• D. Identity data can be shared with third parties without verification

Answer: (A)

Cross-system identity requires that the same identity be verified and used across all integrated systems. When a user is authenticated in one system, that verified identity should be recognized by every other system in the connected environment, with consistent permissions and policies. This creates a single source of truth for who the user is, enables reliable access control, and improves auditing and governance across the whole ecosystem.

If identities are stored separately without a shared verification process, each system may maintain its own, potentially conflicting view of who the user is and what they’re allowed to do. If verification isn’t consistently enforced, credentials could be trusted inconsistently, leading to security gaps. Sharing identity data with third parties without proper verification or safeguards undermines trust and can expose sensitive information.
