+type: Anomaly
+description: The following analytic detects when an application is used to connect a large number of unique ports/targets within a short time frame. Network enumeration may be used by adversaries as a method of discovery, lateral movement, or remote execution. This analytic may require significant tuning depending on the organization and applications being actively used, highly recommended to pre-populate the filter macro prior to activation.

+how_to_implement: This detection relies on Sysmon EventID 3 events being ingested AND tagged into the Network_Traffic datamodel.
+known_false_positives: Various, could be noisy depending on processes in the organization and sysmon configuration used. Adjusted port/dest count thresholds as needed.
