SRG-APP-000383-DNS-000047
Group -
The F5 BIG-IP DNS implementation must prohibit recursion on authoritative name servers.
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 -
SRG-APP-000516-DNS-000078
Group -
The validity period for the RRSIGs covering a zone's DNSKEY RRSet 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 in the parent zone. This strategy limits the time durin...Rule Medium Severity -
SRG-APP-000516-DNS-000089
Group -
An authoritative name server must be configured to enable DNSSEC Resource Records.
The specification for a digital signature mechanism in the context of the DNS infrastructure is in IETF's DNSSEC standard. In DNSSEC, trust in the public key (for signature verification) of the sou...Rule Medium Severity -
SRG-APP-000516-DNS-000095
Group -
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) must be configured with an allow-transfer access control substatement designating the list of hosts from which zone transfer requests ca...Rule Medium Severity -
SRG-APP-000516-DNS-000102
Group -
The F5 BIG-IP DNS must use valid root name servers in the local root zone file.
All caching name servers must be authoritative for the root zone because, without this starting point, they would have no knowledge of the DNS infrastructure and thus would be unable to respond to ...Rule Medium Severity -
SRG-APP-000516-DNS-000109
Group -
The platform on which the name server software is hosted must be configured to respond to DNS traffic only.
Hosts that run the name server software must not provide any other services and therefore must be configured to respond to DNS traffic only. In other words, the only allowed incoming ports/protocol...Rule Medium Severity -
SRG-APP-000516-DNS-000090
Group -
The digital signature algorithm used for DNSSEC-enabled zones must be set to use RSA/SHA256 or RSA/SHA512.
The choice of digital signature algorithm will be based on recommended algorithms in well-known standards. NIST's Digital Signature Standard (DSS) (FIPS186) provides three algorithm choices: - Digi...Rule High Severity -
SRG-APP-000349-DNS-000043
Group -
The F5 BIG-IP DNS server implementation must validate the binding of the other DNS server's identity to the DNS information for a server-to-server transaction (e.g., zone transfer).
Validation of the binding of the information prevents the modification of information between production and review. The validation of bindings can be achieved, for example, by the use of cryptogra...Rule Medium Severity -
SRG-APP-000213-DNS-000024
Group -
A BIG-IP DNS server implementation must provide additional data origin artifacts along with the authoritative data the system returns in response to external name/address resolution queries.
The underlying feature in the major threat associated with DNS query/response (e.g., forged response or response failure) is the integrity of DNS data returned in the response. The security objecti...Rule Medium Severity -
SRG-APP-000214-DNS-000079
Group -
The validity period for the RRSIGs covering the DS RR for a zones 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 in the parent zone. This strategy limits the time durin...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.
