Vulnerability discussion

Without a means for identifying the individual that produced the information, the information cannot be relied upon. Identifying the validity of information may be delayed or deterred.This requirement provides organizational personnel with the means to identify who produced specific information in the event of an information transfer. DNSSEC and TSIG/SIG(0) both use digital signatures to establish the identity of the producer of particular pieces of information. These signatures can be examined and verified to determine the identity of the producer of the information.

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.

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.
