ICS/OT cybersecurity is a critical field that requires continuous learning and collaboration. Below are some of the best resources to enhance your knowledge, whether you’re a beginner or an experienced professional.

1. Books

Books remain one of the best ways to gain deep insights into ICS/OT security. Some must-reads include:
– Industrial Network Security by Eric D. Knapp & Joel Thomas Langill
– Cybersecurity for Industrial Control Systems by Tyson Macaulay
– Securing SCADA Systems by Ronald L. Krutz

You Should Know:

  • Use `nmap` to scan ICS networks safely: 
    nmap -sS -Pn -T4 -p- --script vuln <target_IP>
  • Check firewall rules with: 
    iptables -L -n -v

2. Free Training

CISA offers excellent free training for ICS security:

You Should Know:

  • Use Wireshark to analyze ICS network traffic: 
    wireshark -k -i <interface> -Y "modbus || dnp3"
  • Monitor logs with: 
    tail -f /var/log/syslog | grep "PLC"

3. Certifications

Prove your expertise with certifications like:

  • SANS ICS410: ICS/SCADA Security Essentials
  • ISA/IEC 62443 Cybersecurity Certifications

You Should Know:

  • Test PLC security with PLCscan: 
    git clone https://github.com/SCADACS/PLCscan && cd PLCscan && python2 plcscan.py
  • Check for default credentials using Hydra: 
    hydra -L users.txt -P passwords.txt <PLC_IP> modbus

4. Podcasts

Listen to experts discuss real-world ICS threats:

  • The Industrial Security Podcast
  • Unsupervised Learning by Daniel Miessler

You Should Know:

  • Use `Metasploit` for ICS vulnerability testing: 
    msfconsole -q -x "use auxiliary/scanner/scada/modbus_find; set RHOSTS <IP>; run"

5. Conferences

Attend events like:

  • DEF CON ICS Village
  • S4x22 (SCADA Security Scientific Symposium)

You Should Know:

  • Capture ICS traffic with tcpdump: 
    tcpdump -i eth0 -w ics_traffic.pcap 'port 502 or 20000'

What Undercode Say

Continuous learning is key in ICS/OT security. Use tools like Nmap, Wireshark, and `Metasploit` to test defenses. Always follow ethical guidelines and obtain proper authorization before scanning industrial networks.

Expected Output:

nmap -sS -Pn -T4 -p 502,20000 --script scada-check <target_IP>
