Samirbous d358641c45 [New] Multiple Rare Elastic Defend Behavior Rules by Host (#5738)
* [New] Multiple Rare Elastic Defend Behavior Rules by Host

Identifies hosts that triggered multiple distinct Elastic Defend behavior rules, while reducing false positives by
considering only behavior rules that appear on a single host globally (via INLINE STATS). Hosts with two or more
such rare behavior rules are more likely to be compromised and warrant prioritized triage.

* Update multiple_elastic_defend_behavior_rules_same_host_prevalence.toml

* Update multiple_elastic_defend_behavior_rules_same_host_prevalence.toml

* Update multiple_elastic_defend_behavior_rules_same_host_prevalence.toml

* Update multiple_elastic_defend_behavior_rules_same_host_prevalence.toml

* Update multiple_elastic_defend_behavior_rules_same_host_prevalence.toml

rules/

Rules within this folder are organized by solution or platform. The structure is flattened out, because nested file hierarchies are hard to navigate and find what you're looking for. Each directory contains several .toml files, and the primary ATT&CK tactic is included in the file name when it's relevant (i.e. windows/execution_via_compiled_html_file.toml)
