SRG-APP-000383-DNS-000047
Group -
Forwarders on an authoritative Windows 2012 DNS Server, if enabled for external resolution, must only forward to either an internal, non-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 -
SRG-APP-000383-DNS-000047
Group -
The Windows 2012 DNS Server with a caching name server role must restrict recursive query responses to only the IP addresses and IP address ranges of known supported clients.
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-000383-DNS-000047
Group -
The Windows 2012 DNS Server with a caching name server role must be secured against pollution by ensuring the authenticity and integrity of queried records.
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-000440-DNS-000065
Group -
The Windows 2012 DNS Server must implement cryptographic mechanisms to detect changes to information during transmission unless otherwise protected by alternative physical safeguards, such as, at a minimum, a Protected Distribution System (PDS).
Encrypting information for transmission protects information from unauthorized disclosure and modification. Cryptographic mechanisms implemented to protect information integrity include, for exampl...Rule Medium Severity -
SRG-APP-000516-DNS-000078
Group -
The validity period for the RRSIGs covering a zones 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-000084
Group -
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. With this information it is revealed that the resource record type for the name queried, o...Rule Medium Severity -
SRG-APP-000516-DNS-000085
Group -
The Windows 2012 DNS Servers zone files must have NS records that point to active name servers authoritative for the domain specified in that record.
Poorly constructed NS records pose a security risk because they create conditions under which an adversary might be able to provide the missing authoritative name services that are improperly speci...Rule High Severity -
SRG-APP-000516-DNS-000087
Group -
All authoritative name servers for a zone must be located on different network segments.
Most enterprises have an authoritative primary server and a host of authoritative secondary name servers. It is essential that these authoritative name servers for an enterprise be located on diffe...Rule Medium Severity -
SRG-APP-000516-DNS-000088
Group -
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 -
SRG-APP-000516-DNS-000089
Group -
The Windows 2012 DNS 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 so...Rule High Severity
