FAQPage Schema
How do I filter alert noise from mass internet scans during SOC triage?

Filtering alert noise involves classifying IPs as benign scanners, trusted services, or targeted attackers to distinguish mass internet scans from genuine threats, which reduces SIEM false positives and accelerates SOC triage.

What is the best way to distinguish targeted attackers from noisy scanners in firewall alerts?

The best way to distinguish targeted attackers from noisy scanners is by checking IPs against a threat intelligence layer that classifies addresses as benign scanners, trusted services, or targeted attackers, reducing alert fatigue and enabling faster triage.

Do I need a GreyNoise API key to classify IPs, or can I use community mode?

You do not need a GreyNoise API key to classify IPs; the tool works in community mode without one, but adding an API key provides higher rate limits for increased query volume during incident response.

Can I use this IP classification tool for incident response and SIEM false positive reduction?

Yes, you can use this IP classification tool for incident response and SIEM false positive reduction by leveraging community and RIOT data layers to identify benign scanners and trusted services, prioritizing investigation of suspected targeted activity.

How does classifying IPs as scanners or targeted attackers improve incident response?

Classifying IPs as scanners or targeted attackers improves incident response by reducing alert fatigue, enabling security teams to quickly distinguish mass internet scans from genuine threats and prioritize investigation of suspected targeted activity.
