WDNS-SC-000019 - The Windows 2012 DNS Server must protect the authenticity of zone transfers via transaction signing.


Without identifying devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. This applies to server-to-server (zone transfer) transactions 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.

TSIG and SIG(0) are not configurable in Windows 2012 DNS Server.

To meet the requirement for authentication between Windows DNS servers, IPsec will be implemented between the Windows DNS servers which hosts any non-AD-integrated zones.

NOTE: Nessus has provided the target output to assist in reviewing the benchmark to ensure target compliance.


Complete the following procedures twice for each pair of name servers.

First create a rule for UDP connections, and then create a rule for TCP connections.

Refer to the U_Windows_Domain_Name_Service_2012_Overview.pdf for Microsoft links for this procedure.

Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account.

Press Windows Key + R, execute gpme.msc to open the Group Policy Management feature.

In the Browse for Group Policy Object dialog box, double-click Domain Controllers.domain.com.

Click Default Domain Controllers Policy and click OK.

In the console tree, open Computer Configuration\Policies\Windows Settings\Security Settings\Windows Firewall with Advanced Security\Windows Firewall with Advanced Security - LDAP.

Right-Click Connection Security Rules and select New.

For Rule Type, select the 'Server-to-server' radio button, click Next.

For Endpoint 1 and Endpoint 2, select 'These IP addresses:' and add the IP addresses of all DNS servers, click Next.

For Requirements, select 'Request authentication for inbound and outbound connections', click Next.

For Authentication Method, select Computer certificate and from the 'Signing Algorithm:' drop-down, select 'RSA (default)'.

From the 'Certificate store type:' drop-down, select 'Root CA (default).

From the 'CA name:', click Browse and select the certificate generated by the internally-managed server performing the Active Directory Certificate Services (AD CS) role, click Next.

On Profile, accept default selections, click Next.

On Name, enter a name applicable to the rule's function (i.e., DNSSEC UDP), click Finish.
