You Should Know: Essential Commands & Tools for OT/ICS Security
Networking & Security Fundamentals
– `nmap` (Network Scanning)
nmap -sS -A -T4 192.168.1.1
– `tcpdump` (Packet Capture)
tcpdump -i eth0 -w ot_traffic.pcap
– `Wireshark` (Traffic Analysis)
wireshark ot_traffic.pcap
Industrial Protocol Analysis
- Modbus Testing with `mbpoll`
mbpoll -a 1 -b 9600 -P none -t 3 -r 1 -c 5 /dev/ttyUSB0
- DNP3 Security with `dnp3-cli`
dnp3-cli --host 10.0.0.1 --port 20000 --scan
Incident Response in OT Environments
- Log Analysis with `grep`
grep -i "unauthorized" /var/log/syslog
- Memory Forensics with `Volatility`
volatility -f memory_dump.raw pslist
Penetration Testing for OT Systems
- Metasploit for ICS Exploits
msfconsole use exploit/windows/scada/exploit_module set RHOSTS 192.168.1.100 exploit
- PLC Hacking with `PLCinject`
python plcinject.py --target 10.0.0.2 --command "STOP"
What Undercode Say
OT/ICS security requires a mix of certifications, hands-on experience, and deep knowledge of industrial protocols. Always:
– Monitor network traffic (tcpdump, Wireshark).
– Harden PLCs and RTUs (disable unused services).
– Use segmentation (iptables, VLANs).
– Stay updated on ICS vulnerabilities (CVE databases).
Expected Output: A structured learning path with practical commands for securing OT environments.
