Note: For Infoblox DNS systems on a Classified network, this requirement is Not Applicable.

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.
