🛡 Wazuh Mastery Pack · 10 of 15 — Active Response
Detection without response is just expensive logging.
This cheat sheet is Wazuh's killer feature: built-in response scripts (firewall-drop, disable-account, host-deny), the <command> + <active-response> wiring in ossec.conf, and a Bash skeleton for writing your own AR script.
What you can automate today:
🔹 Block an IP for 10 minutes after 5 failed SSH attempts
🔹 Disable a Windows account that fired a credential-dumping detection
🔹 Kill a malicious process the moment FIM sees it write to a sensitive path
🔹 Null-route an IP across every Wazuh agent simultaneously
Two warnings I learned the hard way:
⚠️ Test ARs in lab. A misfire on rule 5715 (failed SSH from your own admin IP) can lock you out of your own server.
⚠️ Use timeouts. Permanent firewall rules age into accidental black holes within weeks.
