CrowdStrike External Alerts

Elastic Detection Rules

View Source
Summary
The "CrowdStrike External Alerts" rule generates detection alerts for every CrowdStrike alert sent to specific indices, enabling real-time investigation of security events captured by the CrowdStrike Falcon platform. This rule facilitates a swift response to potential threats by offering insights into the behavior and underlying context of detected anomalies through various investigation steps. Analysts are encouraged to review associated processes, file paths, command lines, user accounts, and host involvement to determine the legitimacy of activities flagged by CrowdStrike alerts. Additionally, the setup of this rule requires the CrowdStrike integration to be properly configured to ingest alerts into the specified index pattern. If used with another similar rule, users should implement exception handling to avoid duplicate alert notifications.
