Title

The Infoblox system 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

Infoblox systems allow configuration of DNS auditing based on selectable events. Navigate to Data Management >> DNS and select "Grid DNS Properties". Toggle Advanced mode, and review the "Logging" tab. When complete, click "Cancel" to exit the "Properties" screen. Validate that at a minimum the following categories are enabled; general, config, network, transfer-in, transfer-out, security. If these categories are not enabled 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

Navigate to Data Management >> DNS. Select "Grid DNS Properties". Toggle Advanced mode, and review the "Logging" tab. Enable the following categories using the check box; general, config, network, transfer-in, transfer-out, security. When complete, click "Save & Close" to save the changes and exit the "Properties" screen. Perform a service restart if necessary.
