A beginner-friendly guide explaining how to create, test, and refine custom Wazuh rules to turn raw logs into meaningful, environment-specific security detections.
Customizing Wazuh enables a shift from generic rules to environment-specific detections, reducing noise and enabling proactive, risk-based defense.
In this document, I will show you how you can simulate (preferably in a lab environment) various attacks that have been carried out by attackers in the past or are still being carried out today.
Your SIEM fires dozens of high-severity alerts every day. Your GRC tool sits separately, waiting for someone to manually log risks. The gap between detection and documentation is where compliance breaks down, and where audit findings are born. This guide closes that gap entirely.
This lab demonstrates an alternative approach: deploying a dedicated probe server in promiscuous mode, equipped with Suricata and a Wazuh agent, in order to detect multiple categories of web attacks without installing any agent on the target application server.
The question less of whether Wazuh has every capability out of the box. But more of whether your team does.
This time I configured Wazuh to detect a SYN flood attack using a custom rule and a custom decoder that extracts the attacker’s IP from iptables kernel logs.
