Prioritizing Alerts Triage with Higher-Order Detection Rules

**Executive summary:** This blog post explains Elastic's Higher-Order Rules (HOR) approach for correlating alerts across entities, data sources, and time to raise detection confidence and reduce analyst workload; it provides design principles (entity-based correlation, cross-data visibility, time/prevalence awareness), numerous ES|QL/EQL query examples for endpoint, network, and observability correlations, and discusses operational trade-offs like scheduling latency, tuning base rules, and query cost.
