SCADA (Supervisory Control and Data Acquisition) systems are crucial for monitoring and controlling industrial processes, while Wazuh provides robust XDR and SIEM capabilities. Combining these tools enhances security for Operational Technology (OT) environments.
You Should Know:
1. Installing Wazuh for SCADA Monitoring
To deploy Wazuh for SCADA security:
On Ubuntu/Debian: curl -sO https://packages.wazuh.com/key/GPG-KEY-WAZUH sudo mv GPG-KEY-WAZUH /usr/share/keyrings/wazuh-archive-keyring.gpg echo "deb [signed-by=/usr/share/keyrings/wazuh-archive-keyring.gpg] https://packages.wazuh.com/4.x/apt/ stable main" | sudo tee /etc/apt/sources.list.d/wazuh.list sudo apt update sudo apt install wazuh-manager sudo systemctl enable --now wazuh-manager
2. Configuring Rapid SCADA for Wazuh Integration
Modify Rapid SCADA configuration to forward logs to Wazuh:
<!-- Example in Rapid SCADA config --> <WazuhIntegration> <ServerIP>192.168.1.100</ServerIP> <Port>1514</Port> </WazuhIntegration>
3. Setting Up Wazuh Agent on SCADA Systems
Install Wazuh agent on SCADA endpoints:
For Windows (PowerShell): Invoke-WebRequest -Uri https://packages.wazuh.com/4.x/windows/wazuh-agent-4.7.2-1.msi -OutFile wazuh-agent.msi msiexec.exe /i wazuh-agent.msi /qn WAZUH_MANAGER='wazuh-server-ip' WAZUH_AGENT_GROUP='scada'
4. Enabling File Integrity Monitoring (FIM) for SCADA
Configure Wazuh to monitor critical SCADA files:
{
"fim": {
"directories": [
"/opt/scada/config",
"/var/log/scada"
],
"interval": "1h"
}
}
5. Detecting Anomalies in SCADA Traffic
Use Wazuh rules to detect unusual SCADA network activity:
<group name="scada,"> <rule id="100100" level="10"> <if_sid>5716</if_sid> <match>Unauthorized MODBUS access</match> <description>Possible SCADA intrusion attempt</description> </rule> </group>
6. Automated Response to Threats
Set up active responses in Wazuh:
Block suspicious IPs via firewall:
{
"command": "firewall-drop",
"location": "all",
"timeout": 600
}
What Undercode Say
Securing SCADA systems with Wazuh ensures real-time threat detection, compliance, and incident response. Key takeaways:
– Use FIM to track unauthorized changes in SCADA configurations.
– Monitor MODBUS/TCP traffic for anomalies.
– Deploy automated blocking for malicious IPs.
– Regularly update Wazuh rules for new SCADA threats.
For deeper integration, refer to the guide: Wazuh & Rapid SCADA Integration.
Expected Output:
A hardened SCADA environment with Wazuh SIEM providing real-time alerts, intrusion prevention, and compliance logging.
