Microsoft Windows Server Domain Name System (DNS) Security Technical Implementation Guide
Rules, Groups, and Values defined within the XCCDF Benchmark
-
Primary authoritative name servers must be configured to only receive zone transfer requests from specified secondary name servers.
Authoritative name servers (especially primary name servers) should be configured with an allow-transfer access control substatement designating the list of hosts from which zone transfer requests ...Rule Medium Severity -
The Windows DNS Servers zone database files must not be accessible for edit/write by users and/or processes other than the Windows DNS Server service account and/or the DNS database administrator.
Discretionary Access Control (DAC) is based on the premise that individual users are "owners" of objects and therefore have discretion over who should be authorized to access the object and in whic...Rule Medium Severity -
The Windows DNS Servers zone files must not include resource records that resolve to a fully qualified domain name residing in another zone.
If a name server could claim authority for a resource record in a domain for which it was not authoritative, this would pose a security risk. In this environment, an adversary could use illicit con...Rule Medium Severity -
AAAA addresses must not be configured in a zone for hosts that are not dual stack.
DNS is only responsible for resolving a domain name to an IP address. Applications and operating systems are responsible for processing the IPv6 or IPv4 record that may be returned. A denial of s...Rule Medium Severity -
The secondary Windows DNS name servers must cryptographically authenticate zone transfers from primary name servers.
Authenticity of zone transfers within Windows Active Directory (AD)-integrated zones is accomplished by AD replication. Without authenticating devices, unidentified or unknown devices may be introd...Rule Medium Severity -
The Windows DNS primary server must only send zone transfers to a specific list of secondary name servers.
Primary name servers also make outbound connection to secondary name servers to provide zone transfers and accept inbound connection requests from clients wishing to provide a dynamic update. Prima...Rule Medium Severity -
The Windows DNS Server permissions must be set so the key file can only be read or modified by the account that runs the name server software.
To enable zone transfer (requests and responses) through authenticated messages, it is necessary to generate a key for every pair of name servers. The key can also be used for securing other transa...Rule Medium Severity -
The Windows DNS Server's IP address must be statically defined and configured locally on the server.
The major threat associated with DNS forged responses or failures is the integrity of the DNS data returned in the response. The principle of DNSSEC is to mitigate this threat by providing data ori...Rule Medium Severity -
The Windows DNS Server must use DNSSEC data within queries to confirm data origin to DNS resolvers.
The major threat associated with DNS forged responses or failures is the integrity of the DNS data returned in the response. The principle of DNSSEC is to mitigate this threat by providing data ori...Rule Medium Severity -

The content of the drawer really is up to you. It could have form fields, definition lists, text lists, labels, charts, progress bars, etc. Spacing recommendation is 24px margins. You can put tabs in here, and can also make the drawer scrollable.
