Vulnerability V-259346

Note: This check is not applicable for Windows DNS Servers that host only Active Directory-integrated zones or for Windows DNS Servers on a classified network. Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account. Open an elevated Windows PowerShell prompt on a DNS server using the Domain Admin or Enterprise Admin account. Type the following command, where example.com is replaced with the zone hosted on the DNS Server: PS C:\> Get-DnsServerResourceRecord -ZoneName example.com <enter> All of the zone's resource records will be returned. This should include the NSEC3 RRs, as depicted below. If NSEC3 RRs are not returned for the zone, this is a finding. 2vf77rkf63hrgismnuvnb8...

Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account. If not automatically started, initialize the Server Manager window by clicking its icon from the bottom left corner of the screen. Once the Server Manager window is initialized, from the left pane, click to select the DNS category. From the right pane, under the "SERVERS" section, right-click the DNS server. From the context menu that appears, click "DNS Manager". On the opened DNS Manager snap-in from the left pane, expand the server name and then expand "Forward Lookup Zones". From the expanded list, click to select the zone. Right-click the zone and select DNSSEC >> Sign the Zone. Re-sign the zone using an NSEC3 algorithm (RSA/SHA-1 (NSEC3), RSA/SHA-256, RSA/SHA-512).
