The Windows DNS Server with a caching name server role must restrict recursive query responses to only the IP addresses and IP address ranges of known supported clients.

Description
A potential vulnerability of DNS is that an attacker can poison a name server's cache by sending queries that will cause the server to obtain host-to-IP address mappings from bogus name servers that respond with incorrect information. Once a name server has been poisoned, legitimate clients may be directed to nonexistent hosts (which constitutes a denial of service) or hosts that masquerade as legitimate ones to obtain sensitive data or passwords. To guard against poisoning, name servers specifically fulfilling the role of providing recursive query responses for external zones must be segregated from name servers authoritative for internal zones.

Who does this work

10 NICE work roles and 9 EC-Council certifications.

This is an inference across published mappings, not a single claim by anyone. This check maps to a control, which maps to a Cybersecurity Framework outcome, which NIST assigns to the work roles below. EC-Council separately maps its certifications to those same roles.

A certification prepares someone for a role. It is not evidence that a holder is qualified, and neither NIST nor EC-Council has stated that any certification here addresses this check.

Work-role assignments published by NIST (NICE Framework Components 2.2.0 and the CSF 2.0 OLIR crosswalk). Certification mappings published by EC-Council.

Check Text (C-259343r1156949_chk)

Note: Sinkhole name servers host records that are manually added and for which the name server is not authoritative. It is configured and intended to block resolvers from reaching a destination by directing the query to a sinkhole. If the sinkhole name server is not authoritative for any zones and serves only as a caching/forwarding name server, this check is not applicable. The non-Active Directory (AD)-integrated, standalone, caching Windows DNS Server must be configured to be DNSSEC aware. When performing caching and lookups, the caching name server must be able to obtain a zone signing key (ZSK) DNSKEY record and corresponding RRSIG record for the queried record. It will use this information to compute the hash for the hostname being resolved. The caching name server decrypts the RRSIG record for the hostname being resolved with the zone's ZSK to get the RRSIG record hash. The caching name server compares the hashes and ensures they match. If the non-AD-integrated, standalone, caching Windows DNS Server is not configured to be DNSSEC aware, this is a finding.

Fix Text (F-62990r945243_fix)

Implement DNSSEC on all non-AD-integrated, standalone, caching Windows DNS Servers to ensure the caching server validates signed zones when resolving and caching.
