The DNS implementation must limit the number of concurrent sessions for zone transfers to the number of secondary name servers.
Limiting the number of concurrent sessions reduces the risk of Denial of Service (DoS) to the DNS implementation. Name servers do not have direct user connections but accept client connections fo...Rule Medium Severity -

The DNS server implementation must be configured to provide audit record generation capability for DoD-defined auditable events within all DNS server components.
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 actua...Rule Medium Severity -

Group -
The DNS server implementation must produce audit records containing information to establish what type of events occurred.
Auditing and logging are key components of any security architecture. It is essential for security personnel to know what is being performed on the system, where an event occurred, when an event oc...Rule Medium Severity -

Group -
The DNS server implementation must produce audit records containing information to establish when (date and time) the events occurred.
Without establishing when events occurred, it is impossible to establish, correlate, and investigate the events relating to an incident. Associating event types with detected events in the applic...Rule Medium Severity -

The DNS server implementation must produce audit records containing information to establish where the events occurred.
Without establishing where events occurred, it is impossible to establish, correlate, and investigate the events relating to an incident. Associating information about where the event occurred with...Rule Medium Severity -
SRG-APP-000098
Group -
The DNS server implementation must produce audit records containing information to establish the source of the events.
Without establishing the source of the event, it is impossible to establish, correlate, and investigate the events leading up to an outage or attack. Associating information about the source of the...Rule Medium Severity -
SRG-APP-000099
Group -
The DNS server implementation must produce audit records that contain information to establish the outcome of the events.
Without information about the outcome of events, security personnel cannot make an accurate assessment about whether an attack was successful or if changes were made to the security state of the sy...Rule Medium Severity -
SRG-APP-000100
Group -
The DNS server implementation must generate audit records containing information that establishes the identity of any individual or process associated with the event.
Without information that establishes the identity of the subjects (i.e., users or processes acting on behalf of users) associated with the events, security personnel cannot determine responsibility...Rule Medium Severity
