Domain Name System (DNS) SRG Version Comparison

There are 1 differences between versions v2 r4 (Oct. 23, 2015) (the "left" version) and v3 r2 (May 15, 2024) (the "right" version).

Check SRG-APP-000353-DNS-000045 was removed from the benchmark in the "right" version. The text below reflects the old wording.

This check's original form is available here.

Title

The DNS server implementation must be configured to allow DNS administrators to change the auditing to be performed on all DNS server components, based on all selectable event criteria.

Check Content

Review the DNS server implementation configuration to determine if the DNS server is configured to allow DNS administrators to change the auditing to be performed on all DNS server components, based on all selectable event criteria. If the DNS server is not configured to allow DNS administrators to change the auditing to be performed on all DNS server components, based on all selectable event criteria, this is a finding.

Discussion

If authorized individuals do not have the ability to modify auditing parameters in response to a changing threat environment, the organization may not be able to effectively respond, and important forensic information may be lost. This requirement enables organizations to extend or limit auditing as necessary to meet organizational requirements. Auditing that is limited to conserve information system resources may be extended to address certain threat situations. In addition, auditing may be limited to a specific set of events to facilitate audit reduction, analysis, and reporting. Organizations can establish time thresholds in which audit actions are changed, for example, near real-time, within minutes, or within hours. For a DNS server, the actual auditing is performed by the OS/NDM, but the configuration to trigger the auditing is controlled by the DNS server.

Fix

Configure the DNS server to allow DNS administrators to change the auditing to be performed on all DNS server components, based on all selectable event criteria.
