TL;DR : Splunk is a daunting SIEM to learn, but this learning curve can be flattened by learning to use the basic building blocks which make up most Splunk searches.
A Detection Engineer’s Guide
When I first got my start in cybersecurity, Splunk was one of the most daunting platforms to use. The SIEM had an overwhelming amount of functions and patterns to learn. However, these same functions and patterns provide Splunk detection engineers with near-unrivaled versatility. When used properly, the platform is an exceptional asset for data exploration. This article aims to serve as a guide for future detection developers or analysts looking to start their Splunk-ing journey.
Search Efficiency
Queries (or searches) in Splunk each consume resources from a finite pool. Poorly written queries will consume outsized resources from that pool, and may or may not return the results you’re looking for. If enough inefficient searches are performed, it could impact the performance of all detections and searches.
To prevent any one user from bogging down the whole platform, most organizations configure Splunk to limit the resources any one user/group can consume. If you consume too many resources, Splunk will begin throttling your queries by putting your searches in a “queued” state. Inefficient searches take way longer to process and cause the SIEM to slow down your future searches.
If you want to be an efficient detection developer, write efficient queries.

The following guidelines can help keep your searches effective and efficient. These guidelines boil down to …
