Splunk SPL (Search Processing Language) is the pipe-based query language used in Splunk Enterprise, Splunk Cloud, and Splunk Enterprise Security to interrogate ingested logs. A query starts with a search filter, then chains commands such as stats, eval, rex, lookup, join, tstats, transaction, and timechart through the pipe operator. Detection engineers express correlation rules in SPL, threat hunters use it for ad-hoc investigations, and analysts build dashboards and reports on top of it. Skill with SPL is one of the most marketable abilities for SOC and detection-engineering roles, alongside KQL (Microsoft Sentinel) and YARA-L (Google Chronicle). Performance considerations such as accelerated data models and indexed tokens matter at scale.

Defences for Splunk SPL Query typically combine technical controls and operational practices, as detailed in the full definition above.
