CompTIA has announced a groundbreaking new certification—SecOT+—designed to bridge the gap between IT cybersecurity and Operational Technology (OT) security. This certification is tailored for professionals looking to secure critical infrastructure, including:
– Power plants
– Water treatment facilities
– Manufacturing plants
– Transportation systems (trains, planes, and automobiles)
– Refineries and farms

Expected to launch in 2026, SecOT+ will serve as an entry point for IT professionals transitioning into OT cybersecurity, complementing (but not replacing) existing certifications like ISA/IEC 62443 and SANS ICS/OT courses.

You Should Know: Essential OT Security Commands & Practices

1. Network Segmentation in OT Environments

OT networks must be isolated from IT networks to minimize attack surfaces. Key commands: 

 Linux: Isolate OT network using iptables 
sudo iptables -A FORWARD -i eth0 -o eth1 -j DROP 
sudo iptables -A FORWARD -i eth1 -o eth0 -j DROP

Windows: Check network interfaces 
Get-NetAdapter | Where-Object { $_.Status -eq "Up" }

2. Monitoring Industrial Control Systems (ICS)

Use Wireshark to analyze OT network traffic:

wireshark -k -i eth0 -Y "modbus || dnp3 || opcua"

3. Securing PLCs (Programmable Logic Controllers)

  • Disable unused ports: 
    nmap -sT -p- <PLC_IP>
  • Update firmware securely: 
    openssl s_client -connect <PLC_IP>:443 -verify_return_error

4. Detecting Anomalies in OT Networks

  • Zeek (Bro) IDS for ICS protocols: 
    zeek -i eth0 -C -s modbus.bro
  • Windows Event Logs for OT Security: 
    Get-WinEvent -LogName "Security" | Where-Object { $_.Id -eq 4688 }

5. Hardening OT Devices

  • Linux-based OT devices: 
    sudo apt install unattended-upgrades 
sudo dpkg-reconfigure --priority=low unattended-upgrades
  • Windows-based HMIs (Human-Machine Interfaces): 
    Set-ItemProperty -Path "HKLM:\SYSTEM\CurrentControlSet\Control\Lsa" -Name "RunAsPPL" -Value 1

What Undercode Say

The of SecOT+ is a significant step toward standardizing OT cybersecurity knowledge. As critical infrastructure becomes more digitized, professionals must master:
– Network segmentation (IT/OT convergence risks)
– ICS protocol security (Modbus, DNP3, OPC UA)
– PLC & SCADA hardening
– Anomaly detection in OT traffic

Future attacks on OT systems will likely exploit legacy protocols, weak authentication, and unpatched devices. SecOT+ will help build a workforce capable of defending against these threats.

Prediction

By 2027, OT cybersecurity certifications will become as essential as traditional IT security certs due to increasing attacks on critical infrastructure.

Expected Output:

  • OT Network Segmentation (iptables, Windows Firewall)
  • ICS Traffic Analysis (Wireshark, Zeek)
  • PLC Security (nmap, openssl)
  • OT Anomaly Detection (Windows Event Logs, Zeek scripts)
