Fix Recommendation

Navigate to Data Management >> DNS >> Zones tab.

Select a zone and click "Edit".
Click on "Zone Transfers" tab, and click "Override" for the "Allow Zone Transfers to" section.
Use the radio button to select "Set of ACEs" and the "Add" dropdown to configure a TSIG key. It is important to verify that both the Infoblox and other DNS server have the identical TSIG configuration.
When complete, click "Save & Close" to save the changes and exit the "Properties" screen.

Perform a service restart if necessary.

Verify zone transfers are operational after configuration of TSIG.

Check Contents

Navigate to Data Management >> DNS >> Zones tab.

Review each zone by clicking Edit and inspecting the "Name Servers" tab.

If the all entries in the "Type" column are configured as "Grid", this check is not applicable.

Verify that each zone which contains non-Grid name servers is further verified by inspection of the "Zone Transfers" tab and configuration of TSIG Access Control Entry (ACE).

If there is a non-Grid system which utilizes zone transfers but does not have a TSIG key, this is a finding.

When complete, click "Cancel" to exit the "Properties" screen.
