Watch over DNS traffic with Corelight and Splunk

Corelight sensors put your organization in the best position to watch over DNS traffic with a rich, powerful Network Traffic Analysis (NTA) data set. This article highlights the benefits of Corelight DNS logs, and demonstrates how Splunk Enterprise Security can reach a new level of functionality through integration with Corelight.

DNS log

Corelight improves DNS monitoring in several ways, starting with extracting DNS metadata directly from packet data, to provide query and response in a single log. Corelight can dynamically detect DNS traffic, allowing you to monitor DNS traffic to external servers, see DNS traffic on non-standard ports, and more. Corelight DNS logs link directly to the connection log, enabling you to monitor DNS bandwidth usage, source ports, destination port, connection counts, and more.

Corelight/Splunk integration

Corelight’s onboard Splunk integration means that data extraction and normalization happens out of the box. With Corelight App for Splunk and/or TA for Corelight, the data is also CIM compliant, allowing the data to populate the Network Resolution (DNS) data model for maximum efficiency at search time and in the Splunk Enterprise Security app.

Corelight DNS log and Splunk Enterprise Security

Many Splunk Enterprise Security deployments never realize the value of DNS workflows because they lack relevant, normalized data or can’t correlate data against other data sets. Corelight helps them overcome these challenges rapidly with built-in dashboards and correlation searches. It’s simple to correlate DNS data with network metrics like bandwidth, and from there, create advanced correlations that can identify and track complex attacks.
