The DNS implementation must protect the authenticity of communications sessions for queries.

Description
The underlying feature in the major threat associated with DNS query/response (i.e., forged response or response failure) is the integrity of DNS data returned in the response. An integral part of integrity verification is to ensure that valid data has originated from the right source. DNSSEC is required for securing the DNS query/response transaction by providing data origin authentication and data integrity verification through signature verification and the chain of trust.

This is dependent on the DoD wide deployment of DNSSEC. Until full deployment is realized this vulnerability may be considered NA provided DNSSEC is NOT enabled on the DNS server. Review the DNS server configuration to determine if communication sessions for queries are provided integrity protections. If communications sessions do not employ authenticity protection, this is a finding.

Fix Text (F-SRG-APP-000219-DNS-000030_fix)
Configure the DNS server to employ mechanisms to protect the authenticity of communications sessions for queries.
