Discussion

Without a means for identifying the individual who produced the information, the information cannot be relied on. 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 uses 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.

2. Toggle Advanced Mode and click on the "DNSSEC" tab. 
3. Verify that both "Enable DNSSEC" and "Enable DNSSEC validation" are enabled.
4. When complete, click "Cancel" to exit the "Properties" screen. 

If both "Enable DNSSEC" and "Enable DNSSEC validation" are not enabled, this is a finding.
