Summary
The detection rule for CrowdStrike Multiple LOW Severity Alerts is designed to identify instances of multiple alerts categorized as 'LOW' severity from CrowdStrike logs. These alerts signal minor suspicious activities or policy violations that, while not immediately critical, warrant attention to prevent potential escalation into more serious security threats. By analyzing data from the CrowdStrike stream, the rule renames several fields for clarity, aggregates alert statistics based on the source IP and host, and filters to show occurrences of at least three alerts of the same type. The implementation requires integrating the CrowdStrike Falcon Streaming API into a logging or SIEM solution to capture and analyze the relevant JSON logs. Regular reviews of these low-severity alerts are necessary as they can highlight behavioral anomalies that could indicate malicious activities if not addressed promptly.
