Vulnerability V-259351

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. Press the Windows key + R and 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, click to select the zone. Review the zone's RRs in the right windowpane. Review the DNSKEY encryption in the Data column. Example: [DNSKEY][RsaSha1][31021] Confirm the encryption algorithm specified in the DNSKEY's data is at RsaSha1, at a minimum. If the specified encryption algorithm is not RsaSha1 or stronger, this is a finding.

Sign or re-sign the hosted zone(s) on the DNS server being validated. Log on to the DNS server using the Domain Admin or Enterprise Admin account or Local Administrator account. Press the Windows key + R and 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" using either approved saved parameters or approved custom parameters.
