IDS/IPS Alerts (Snort/Suricata)

Location

Description

Signature-based and anomaly-based intrusion detection alerts with rule SID, severity, source/destination IP and port, protocol, alert message, and reference to the triggering packet.

Forensic Value

IDS alerts provide immediate, high-confidence indicators when signature matches occur for known exploits, malware communication patterns, or policy violations. Suricata eve.json output includes the triggering rule details and associated flow metadata. Even in high-noise environments, filtering by severity and correlating with other artifacts narrows the focus. Alert timestamps establish the earliest detection of malicious activity, supporting timeline construction.
