What is DBIOS?

• A. Defense Biometric Identification System; positive identification through electronic interrogation of credentials; mandatory use.
• B. Digital Bank for Information Operations System
• C. Data Biometric Internet Overlay System
• D. Defense Base Information Operations Standards

Answer: (A)

The main idea is how biometric-based identity verification is enforced in security environments. Defense Biometric Identification System refers to a system that performs positive identification by electronically interrogating credentials and biometric data to confirm a person’s true identity before granting access. This approach is used to ensure that someone is who they claim to be, not just that their credentials are valid, which is crucial for sensitive facilities and information systems. The mandatory use aspect means enrollment and use of the system are required for access, providing consistent and enforceable control across personnel. The other options describe concepts that don’t fit this setting: one mentions a digital banking system, another a generic internet overlay, and the last a standards framework for defense information operations, none of which capture biometric identity verification with mandatory use.
