You Should Know: Essential OT/ICS Cybersecurity Commands & Tools
Linux-Based OT Security Tools
1. Nmap (Network Scanning)
nmap -sS -Pn -T4 -p- <target_IP>
Scans for open ports in OT environments.
2. Wireshark (Traffic Analysis)
sudo wireshark
Analyze ICS/SCADA network traffic for anomalies.
3. Metasploit (Penetration Testing)
msfconsole use auxiliary/scanner/scada/modbus_findunit set RHOSTS <target_IP> run
Tests Modbus protocol vulnerabilities.
4. Snort (IDS for OT Networks)
snort -A console -q -c /etc/snort/snort.conf -i eth0
Monitors OT network traffic for intrusions.
5. Modbus CLI Tools
sudo apt install libmodbus-dev modbus read <device_IP> 502
Interacts with Modbus-enabled devices.
Windows-Based OT Security Commands
1. Check Open Ports (PowerShell)
Test-NetConnection -ComputerName <target_IP> -Port 502
Verifies if Modbus (502) is accessible.
2. Firewall Rules for ICS Traffic
New-NetFirewallRule -DisplayName "Block ICS Unauthorized" -Direction Inbound -Protocol TCP -LocalPort 502 -Action Block
Blocks unauthorized Modbus access.
3. Log Analysis (Event Viewer)
Get-WinEvent -LogName "Security" | Where-Object {$_.Id -eq 4625}
Checks failed login attempts on ICS systems.
4. SCADA Patch Management
wuauclt /detectnow /updatenow
Forces Windows updates on SCADA workstations.
What Undercode Say
OT/ICS cybersecurity requires continuous monitoring, threat intelligence, and hands-on command-line expertise. The provided tools and commands help in securing critical infrastructure. Always verify network segmentation, disable unnecessary services, and apply strict access controls.
Expected Output:
- A hardened OT network with monitored traffic.
- Regular vulnerability scans using Nmap and Metasploit.
- Logged and analyzed security events via Snort/Wireshark.
- Updated ICS devices with restricted Modbus/TCP access.
Stay vigilant and keep learning! π¨
