The DNS server implementation must uniquely identify the other DNS server before responding to a server-to-server transaction.

Description
Without identifying devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. This applies to server-to-server (zone transfer) transactions only and is provided by TSIG/SIG(0), which enforces mutual server authentication using a key that is unique to each server pair (TSIG) or using PKI-based authentication (SIG(0)), thus uniquely identifying the other server.

Check Text ( C-SRG-APP-000158-DNS-000015_chk )
Review the DNS server implementation configuration to determine if the DNS server uniquely identifies the other DNS server before responding to a server-to-server transaction. If the DNS server does not uniquely identify the other DNS server, this is a finding.

Fix Text (F-SRG-APP-000158-DNS-000015_fix)
Configure the DNS server to uniquely identify the other DNS server before responding to a server-to-server transaction.
