Blue-team SIEM lab: Wazuh 4.7.5 detecting 7 simulated attacks (SSH brute force, Slowloris DoS / CVE-2007-6750, web attacks) with real-time MITRE ATT&CK mapping — 3,726+ alerts.
An end-to-end blue-team lab: a Wazuh 4.7.5 SIEM detecting 7 simulated attacks — from port scanning and SSH brute force to a real CVE exploit (Slowloris DoS) — with every event logged, alerted, and mapped to MITRE ATT&CK in real time. Built from scratch on two virtual machines.
