Detection Query Optimizer

What problem does it solve?

This Skill helps security analysts and engineers write more efficient detection queries for Splunk (SPL), Microsoft Sentinel (KQL), and Elastic Security (EQL/ES|QL), reducing query execution time and resource consumption.

Core Features & Use Cases

• Platform-Specific Guidance: Provides detailed optimization techniques tailored to SPL, KQL, and EQL/ES|QL.
• Search Pipeline Internals: Explains how each SIEM processes queries to identify bottlenecks.
• Anti-Pattern Identification: Highlights common mistakes that lead to slow queries.
• Use Case: A security engineer is experiencing slow performance with a new Splunk detection rule. They use this Skill to understand why and refactor the SPL query to run significantly faster, allowing for more frequent execution.
