For Active Directory-integrated zones, private zone signing keys replicate automatically to all primary DNS servers through Active Directory replication. Each authoritative server signs its own copy of the zone when it receives the key. For optimal performance, and to prevent increasing the size of the Active Directory database file, the signed copy of the zone remains in memory for Active Directory-integrated zones. A DNSSEC-signed zone is only committed to disk for file-backed zones. Secondary DNS servers pull a full copy of the zone, including signatures, from the primary DNS server. If all DNS servers are AD integrated, this check is not applicable. If a DNS server is not AD integrated and has file-backed zones, does not accept dynamic updates and has a copy of the private key corresponding to the ZSK, this is a finding.</rawString> </Rule> <Rule id="V-58651" severity="medium" conversionstatus="pass" title="SRG-APP-000516-DNS-000077" dscresource="None"> <IsNullOrEmpty>False</IsNullOrEmpty> <OrganizationValueRequired>False</OrganizationValueRequired> <OrganizationValueTestString /> <rawString>Note: This check is Not applicable for Windows 2012 DNS Servers that only host Active Directory integrated zones or for Windows 2012 DNS servers on a Classified network.
