Splunk

What is Splunk?

Splunk is a data analytics platform that has become one of the most widely deployed SIEM solutions in enterprise security operations. It ingests machine-generated data from any source, including logs, metrics, network traffic, and application events, indexes it for fast search, and provides a query language called SPL that allows analysts to write complex correlations and aggregations across massive datasets. Splunk's detection framework, powered by Splunk Security Essentials and the ESCU content library, provides hundreds of prebuilt detection rules aligned to MITRE ATT&CK. Its SOAR product, Splunk SOAR, integrates tightly with the SIEM to allow playbooks to execute response actions directly from within investigation workflows. Splunk's flexibility and extensive integration ecosystem make it a common choice for organizations with complex, heterogeneous environments that require custom detection logic and data analysis workflows.

How does Splunk work with Qevlar?

Qevlar integrates with Splunk to query log data and retrieve alerts during automated investigations. When an investigation requires searching across historical data or correlating events from multiple data sources indexed in Splunk, Qevlar can execute SPL queries directly to retrieve the relevant evidence without requiring analyst involvement.
