The major threat associated with DNS forged responses or failures is the integrity of the DNS data returned in the response. The principle of DNSSEC is to mitigate this threat by providing data origin authentication, establishing trust in the source. This requirement enables remote clients to obtain origin authentication and integrity verification assurances for the host/service name to network address resolution information obtained through the service. A DNS server is an example of an information system providing name/address resolution service. Digital signatures and cryptographic keys are examples of additional artifacts. DNS resource records are examples of authoritative data. Applications other than the DNS to map between host/service names and network addresses must provide other means to assure the authenticity and integrity of response data. In the case of DNS, employ DNSSEC to provide an additional data origin and integrity artifacts along with the authoritative data the system returns in response to DNS name/address resolution queries.

Verify Infoblox has DNSSEC validation configured: 1. Navigate to Data Management >> DNS >> Grid DNS Properties (Toolbar menu). 2. Toggle "Advanced Mode" and click the "DNSSEC" tab. 3. Verify both checkboxes for "Enable DNSSEC" and "Enable DNSSEC validation" are selected. 4. When complete, click "Cancel" to exit the "Properties" screen. If both "Enable DNSSEC" and "Enable DNSSEC validation" are not configured, this is a finding. Note: DNSSEC is intended for third-party authenticity determination. Attempting to utilize DNSSEC internally was never an intended use case as it would require every consumer to have a third-party validating resolver installed along with a mechanism for periodic trust anchor distribution/update. Note: DNSSEC validation must be configured when all of the following conditions are met: 1. Root hints or custom root hints are used, 2. Default forwarding is disabled, and 3. Recursion is enabled for the DNS view or member.
1. Navigate to Data Management >> DNS >> Grid DNS Properties (Toolbar menu). 2. Toggle "Advanced Mode" and click the "DNSSEC" tab. 3. Check the boxes for both "Enable DNSSEC" and "Enable DNSSEC validation". 4. When complete, click "Save & Close" to save the changes and exit the "Properties" screen. 5. Perform a service restart if necessary.
