The application must provide additional data origin and integrity artifacts along with the authoritative data the system returns in response to name/address resolution queries.

Description
This control enables remote clients to obtain origin authentication and integrity verification assurances for the host/service name to network address resolution information obtained through the service. A Domain Name System (DNS) server is an example of an information system providing name/address resolution service. Digital signatures and cryptographic keys are examples of additional artifacts. DNS resource records are examples of authoritative data. Information systems using technologies other than the DNS to map between host/service names and network addresses provide other means to assure the authenticity and integrity of response data. The DNS security controls are consistent with, and referenced from, OMB Memorandum 08-23. Rationale for non-applicability: The mobile operating system is responsible for name/address resolution services. If a mobile application were granted the OS privileges necessary to provide name services to other applications, this would enable the name service application to launch a number of IA attacks against other applications.
