The Windows DNS Server must restrict incoming dynamic update requests to known clients.
Limiting the number of concurrent sessions reduces the risk of denial of service (DoS) on any system. A DNS server's function requires it to be able to handle multiple sessions at a time, so limit...Rule Medium Severity -
The Windows DNS Server must be configured to record who added/modified/deleted DNS zone information.
Without a means for identifying the individual that produced the information, the information cannot be relied on. Identifying the validity of information may be delayed or deterred. This requirem...Rule Medium Severity -
The "Manage auditing and security log" user right must be assigned only to authorized personnel.
Without the capability to generate audit records, it would be difficult to establish, correlate, and investigate the events relating to an incident or identify those responsible for one. The actual...Rule Medium Severity -
The validity period for the Resource Record Signatures (RRSIGs) covering the Delegation Signer (DS) Resource Record (RR) for a zone's delegated children must be no less than two days and no more than one week.
The best way for a zone administrator to minimize the impact of a key compromise is by limiting the validity period of RRSIGs in the zone and the parent zone. This strategy limits the time during w...Rule Medium Severity -
The Windows DNS Server must prohibit recursion on authoritative name servers for which forwarders have not been configured for external queries.
A potential vulnerability of DNS is that an attacker can poison a name server's cache by sending queries that will cause the server to obtain host-to-IP address mappings from bogus name servers tha...Rule Medium Severity -
Forwarders on an authoritative Windows DNS Server, if enabled for external resolution, must forward only to an internal, non-Active Directory (AD)-integrated DNS server or to the DOD Enterprise Recursive Services (ERS).
A potential vulnerability of DNS is that an attacker can poison a name server's cache by sending queries that will cause the server to obtain host-to-IP address mappings from bogus name servers tha...Rule Medium Severity -
NSEC3 must be used for all internal DNS zones.
NSEC records list the resource record types for the name, as well as the name of the next resource record. This information reveals that the resource record type for the name queried, or the resour...Rule Medium Severity -
All authoritative name servers for a zone must have the same version of zone information.
The only protection approach for content control of a DNS zone file is the use of a zone file integrity checker. The effectiveness of integrity checking using a zone file integrity checker depends ...Rule Medium Severity -
The Windows DNS Server must be configured to enable DNSSEC Resource Records (RRs).
The specification for a digital signature mechanism in the context of the DNS infrastructure is in the Internet Engineering Task Force's (IETF's) DNSSEC standard. In DNSSEC, trust in the public key...Rule High 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.
