In this article, we explore an advanced OT/ICS cybersecurity lab designed for pentesting and deep diving into PLC and SCADA configurations. The lab, created by Zakhar Bernhardt, allows users to simulate real-world scenarios, test ICS networks, and develop OT SIEM strategies. Here’s what you can do with Labshock:
- Work with PLCs: Set up, configure, and test programmable logic controllers to understand their functionality in ICS environments.
- Learn ICS Networks: Explore network setups, including switches, firewalls, and protocols commonly used in industrial systems.
- Configure SCADA Systems: Practice with SCADA interfaces, simulate industrial processes, and understand data flow between components.
- Simulate Multivendor PLC Setups: Work with multiple PLC types to understand interoperability and differences.
- Test Pentesting Tools: Safely use security tools to identify vulnerabilities and learn how attackers might exploit them.
- Create OT SIEM Rules: Build and test custom correlation rules tailored for OT environments.
- Practice Detection and Response: Simulate attacks or anomalies and develop strategies to detect and respond to them.
Verified Commands and Codes for OT/ICS Cybersecurity
1. PLC Configuration:
<h1>Example command to configure a PLC using OpenPLC-Editor</h1> openplc-editor --config plc_config.xml
2. Network Traffic Monitoring:
<h1>Use tcpdump to capture network traffic on an ICS network</h1> sudo tcpdump -i eth0 -w ics_traffic.pcap
3. SCADA Simulation:
<h1>Start a SCADA simulation using OpenSCADA</h1> openscada --simulate --config scada_config.xml
4. SIEM Rule Creation:
<h1>Example SIEM rule for OT environments using Elasticsearch</h1>
PUT _siem/rules/ot_rule
{
"query": {
"match": {
"event.type": "anomaly"
}
},
"actions": {
"notify": {
"email": "[email protected]"
}
}
}
5. Vulnerability Scanning:
<h1>Use Nmap to scan for vulnerabilities in an ICS network</h1> nmap -sV --script=vuln 192.168.1.0/24
6. Incident Response:
<h1>Isolate a compromised device using iptables</h1> sudo iptables -A INPUT -s 192.168.1.100 -j DROP
