SV-83047r3_rule An Infoblox DNS server must strongly bind the identity of the DNS server with the DNS information using DNSSEC.

Vulnerability discussion

Weakly bound credentials can be modified without invalidating the credential; therefore, non-repudiation can be violated.This requirement supports audit requirements that provide organizational personnel with the means to identify who produced specific information in the event of an information transfer. Organizations and/or data owners determine and approve the strength of the binding between the information producer and the information based on the security category of the information and relevant risk factors.DNSSEC uses digital signatures to verify the identity of the producer of particular pieces of information.

Check content

Note: For Infoblox DNS systems on a Classified network, this requirement is Not Applicable. Validate that DNSSEC validation is enabled by navigating to Data Management >> DNS >> Grid DNS properties, toggle Advanced Mode click on "DNSSEC" tab. Note: DNSSEC validation is only applicable on a grid member where recursion is active. When complete, click "Cancel" to exit the "Properties" screen. If both "Enable DNSSEC" and "Enable DNSSEC validation" are not enabled, this is a finding.

Fix text

DNSSEC validation is enabled by navigating to Data Management >> DNS >> Grid DNS properties, toggle Advanced Mode click on "DNSSEC" tab. Enable both "Enable DNSSEC" and "Enable DNSSEC validation". When complete, click "Save & Close" to save the changes and exit the "Properties" screen. Perform a service restart if necessary.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
