Check: SRG-APP-000215-MAPP-NA
Mobile Application SRG:
SRG-APP-000215-MAPP-NA
(in version v1 r1)
Title
The application must perform data origin authentication and data integrity verification on the name/address resolution responses the system receives from authoritative sources when requested by client systems. (Cat II impact)
Discussion
A recursive resolving or caching Domain Name System (DNS) server is an example of an information system providing name/address resolution service for local clients. Authoritative DNS servers are examples of authoritative sources. Information systems using technologies other than the DNS to map between host/service names and network addresses provide other means to enable clients to verify the authenticity and integrity of response data. 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.
