The secondary Windows DNS name servers must cryptographically authenticate zone transfers from primary name servers.
An XCCDF Rule
Description
<VulnDiscussion>Authenticity of zone transfers within Windows Active Directory (AD)-integrated zones is accomplished by AD replication. Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Device authentication is a solution enabling an organization to manage devices. It is an additional layer of authentication ensuring only specific preauthorized devices can access the system. This requirement 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).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>
