The Infoblox DNS server must authenticate another DNS server before establishing a remote and/or network connection using bidirectional authentication that is cryptographically based.
An XCCDF Rule
Description
<VulnDiscussion>Without authenticating devices, unidentified or unknown devices may be introduced, thereby facilitating malicious activity. Bidirectional authentication provides stronger safeguards to validate the identity of other devices for connections that are of greater risk. This requirement applies to server-to-server (zone transfer) transactions only and is provided by TSIG, which enforces mutual server authentication using a key that is unique to each server pair (TSIG).</VulnDiscussion><FalsePositives></FalsePositives><FalseNegatives></FalseNegatives><Documentable>false</Documentable><Mitigations></Mitigations><SeverityOverrideGuidance></SeverityOverrideGuidance><PotentialImpacts></PotentialImpacts><ThirdPartyTools></ThirdPartyTools><MitigationControl></MitigationControl><Responsibility></Responsibility><IAControls></IAControls>

It is important to verify that both the Infoblox and other DNS server have the identical TSIG configuration and time synchronization before starting this procedure.
1. Navigate to the Data Management >> DNS >> Zones tab.
2. Select a zone and click "Edit". Click on the "Zone Transfers" tab and click "Override" for the "Allow Zone Transfers to" section.
3. Use the radio button to select "Set of ACEs" and the "Add" drop-down to configure a TSIG key.
4. When complete, click "Save & Close" to save the changes and exit the "Properties" screen.
