You Should Know: Essential OT/ICS Cybersecurity Commands & Tools
1. Network Scanning & Enumeration
nmap -sV --script=vuln 192.168.1.1 Scan for vulnerabilities masscan -p1-65535 10.0.0.0/24 --rate=1000 Fast port scanning
2. Modbus & ICS Protocol Testing
python3 modbus-cli.py -h 192.168.1.100 -p 502 Interact with Modbus plcscan -i eth0 Detect PLCs in the network
3. ICS Exploitation (Metasploit)
use exploit/windows/scada/exploit_name set RHOSTS 192.168.1.50 exploit
4. Log Analysis for OT Security
grep "Failed login" /var/log/auth.log Check brute-force attempts journalctl -u ssh --no-pager View SSH logs in Linux
5. Windows ICS Security Commands
Get-NetTCPConnection | Where-Object {$<em>.State -eq "Established"} Check active connections
Get-Process -IncludeUserName | Where-Object {$</em>.CPU -gt 50} Detect suspicious processes
6. Firewall & Traffic Control
iptables -A INPUT -p tcp --dport 502 -j DROP Block Modbus traffic ufw allow from 192.168.1.0/24 to any port 22 Allow SSH only from trusted subnet
What Undercode Say
OT/ICS cybersecurity is critical for protecting industrial infrastructure. These YouTube channels provide free, high-quality training for securing SCADA, PLCs, and industrial networks.
Key Takeaways:
- Use Nmap & Masscan for OT network discovery.
- Modbus & PLCscan help assess industrial devices.
- Metasploit contains ICS-specific exploits.
- Log monitoring detects anomalies in OT environments.
- Firewall rules must restrict unauthorized ICS protocol access.
Expected Output:
A well-secured OT environment with continuous monitoring, restricted access, and up-to-date threat intelligence.
