Perform data integrity verification on the name/address resolution responses the system receives from authoritative sources.

Implementation Guidance

Determine if: - data origin authentication is requested for the name/address resolution responses that the system receives from authoritative sources. - data origin authentication is performed on the name/address resolution responses that the system receives from authoritative sources. - data integrity verification is requested for the name/address resolution responses that the system receives from authoritative sources. - data integrity verification is performed on the name/address resolution responses that the system receives from authoritative sources.

Validation Procedures

Examine: [SELECT FROM: System and communications protection policy; procedures addressing secure name/address resolution services (recursive or caching resolver); system design documentation; system configuration settings and associated documentation; system audit records; system security plan; other relevant documents or records]. Interview: [SELECT FROM: System/network administrators; organizational personnel with information security responsibilities; organizational personnel with responsibilities for managing DNS]. Test: [SELECT FROM: Mechanisms supporting and/or implementing data origin authentication and data integrity verification for name/address resolution services].
