This guide is your path to mastering OT SIEM. Mastering OT SIEM takes more than reading or memorizing checklists. It requires understanding, application, and hands-on practice. The guide covers:
- Theory: What is SCADA, PLC, Tags, and Protocols.
- Step-by-step Lab setup using Labshock.
- Creating a simple SCADA interface to read tags from a PLC.
- Hands-on exercises for real-world ICS experience.

Practice Verified Codes and Commands:
1. SCADA Lab Setup:
<h1>Install Labshock</h1> sudo apt-get update sudo apt-get install labshock <h1>Start Labshock</h1> labshock start
2. Reading Tags from PLC:
import pycomm3
<h1>Connect to PLC</h1>
plc = pycomm3.LogixDriver('192.168.1.1')
plc.open()
<h1>Read tag</h1>
tag_value = plc.read('MyTag')
print(f"Tag Value: {tag_value}")
3. Writing Values to PLC:
<h1>Write value to tag</h1>
plc.write('MyTag', 100)
print("Value written to PLC")
4. Monitoring SCADA Interface:
<h1>Monitor SCADA logs</h1> tail -f /var/log/scada.log
What Undercode Say:
Mastering OT SIEM and SCADA systems is crucial for industrial cybersecurity. The guide provides a comprehensive approach to understanding and applying OT SIEM principles, from theory to hands-on practice. Here are some additional commands and practices to enhance your skills:
1. Network Monitoring:
<h1>Use tcpdump to capture network traffic</h1> sudo tcpdump -i eth0 -w scada_traffic.pcap <h1>Analyze captured traffic with Wireshark</h1> wireshark scada_traffic.pcap
2. System Hardening:
<h1>Disable unused services</h1> sudo systemctl disable unused-service <h1>Update system regularly</h1> sudo apt-get update && sudo apt-get upgrade -y
3. Incident Response:
<h1>Check system logs for anomalies</h1> sudo grep -i "error" /var/log/syslog <h1>Isolate compromised systems</h1> sudo iptables -A INPUT -s 192.168.1.100 -j DROP
4. Backup and Recovery:
<h1>Create a backup of critical files</h1> sudo tar -czvf scada_backup.tar.gz /etc/scada <h1>Restore from backup</h1> sudo tar -xzvf scada_backup.tar.gz -C /
5. Security Auditing:
<h1>Run a security audit with Lynis</h1> sudo lynis audit system <h1>Check for open ports</h1> sudo nmap -sV 192.168.1.1
6. Firewall Configuration:
<h1>Allow specific IP to access SCADA</h1> sudo ufw allow from 192.168.1.50 to any port 502 <h1>Deny all other traffic</h1> sudo ufw default deny incoming
7. User Management:
<h1>Add a new user</h1> sudo adduser newuser <h1>Grant sudo privileges</h1> sudo usermod -aG sudo newuser
8. Log Management:
<h1>Rotate logs to prevent overflow</h1> sudo logrotate -f /etc/logrotate.conf <h1>Monitor log size</h1> du -sh /var/log
9. Patch Management:
<h1>Check for available patches</h1> sudo apt list --upgradable <h1>Apply patches</h1> sudo apt-get upgrade -y
10. Intrusion Detection:
<h1>Install and configure Fail2Ban</h1> sudo apt-get install fail2ban sudo systemctl enable fail2ban sudo systemctl start fail2ban
By following these practices and commands, you can significantly enhance the security and efficiency of your OT SIEM and SCADA systems. The provided guide and resources are invaluable for anyone looking to deepen their understanding and practical skills in industrial cybersecurity.
