WDNS-SC-000028 - The Windows 2012 DNS Server must protect the integrity of transmitted information.

Information

Without protection of the transmitted information, confidentiality and integrity may be compromised since unprotected communications can be intercepted and either read or altered.

Communication paths outside the physical protection of a controlled boundary are exposed to the possibility of interception and modification. Protecting the confidentiality and integrity of organizational information can be accomplished by physical means (e.g., employing physical distribution systems) or by logical means (e.g., employing cryptographic techniques). If physical means of protection are employed, then logical means (cryptography) do not have to be employed, and vice versa.

Confidentiality is not an objective of DNS, but integrity is. DNSSEC and TSIG/SIG(0) both digitally sign DNS information to authenticate its source and ensure its integrity.

Solution

Sign, or re-sign, the hosted zone(s) on the DNS server being validated.

Log on to the Windows 2012 DNS server using the account designated as Administrator or DNS Administrator.

Press Windows Key + R, execute dnsmgmt.msc.

On the opened DNS Manager snap-in from the left pane, expand the server name for the DNS server, and then expand Forward Lookup Zones.

From the expanded list, right-click to select the zone (repeat for each hosted zone), point to DNSSEC, and then click Sign the Zone, either using approved saved parameters or approved custom parameters.
