Building a 24/7 Threat Hunting Pipeline with Wazuh SIEM and Suricata

Proactive Defense vs. Passive Monitoring

Traditional signature-based antivirus software is incapable of stopping fileless malware and living-off-the-land (LotL) binaries. Modern Security Operations Centers require continuous log correlation and behavioral anomaly detection across every endpoint.

Architecting the Telemetry Pipeline

By pairing Wazuh EDR agents on Windows and Linux endpoints with Suricata on network gateways, security teams obtain visibility into both host-level process creation and network-level command-and-control handshakes.

Automated Active Response

When an endpoint attempts multiple failed SSH brute-force authentications or invokes suspicious PowerShell download strings (Invoke-Expression / IEX), the Wazuh agent can execute automated firewall drop rules and isolate the endpoint's network adapter in seconds.
