Honeywell has released its 2025 Cyber Threat Report, focusing on Operational Technology (OT) and Industrial Control Systems (ICS) environments. The report highlights the Top 100 Threats and detection trends, along with Honeywell’s specialized cybersecurity services for critical infrastructure.
Honeywell’s OT/ICS Cybersecurity Services
1. Honeywell Advanced Monitoring and Incident Response (AMIR)
- A Managed Security Service (MSS) for continuous threat monitoring.
2. Honeywell Secure Media Exchange (SMX)
- Enforces USB and removable media protection using Google Threat Intelligence (GTI).
3. Honeywell Cyber Insights
- Provides on-premise OT threat intelligence and data analysis.
4. Honeywell Cyber Watch
- Offers an enterprise-wide OT security posture dashboard with compliance tracking.
5. Honeywell Professional Cybersecurity Services
- Includes risk assessments, defense implementation, and incident response planning.
You Should Know: Practical OT/ICS Security Commands & Steps
1. Monitoring OT Network Traffic
Use Wireshark to analyze ICS protocols (e.g., Modbus, DNP3):
sudo wireshark -k -i eth0 -Y "modbus || dnp3"
2. Detecting Suspicious USB Devices (Linux)
List connected USB devices:
lsusb dmesg | grep -i usb
Block unauthorized USB storage:
echo "install usb-storage /bin/true" | sudo tee /etc/modprobe.d/disable-usb-storage.conf
3. Securing ICS Systems with Firewall Rules
Block unauthorized Modbus traffic:
sudo iptables -A INPUT -p tcp --dport 502 -j DROP
4. Logging OT Security Events
Forward logs to a SIEM (e.g., Splunk, ELK):
sudo rsyslogd -f /etc/rsyslog.conf
5. Detecting OT Malware with YARA
Scan for ICS malware signatures:
yara -r /opt/yara-rules/malware.yar /opt/ot-systems/
What Undercode Say
Honeywell’s report underscores the growing threats to OT/ICS systems, emphasizing the need for USB security, network segmentation, and real-time monitoring. Key takeaways:
– USB attacks remain a major threat → Use Honeywell SMX or disable USB storage.
– Unsecured Modbus/DNP3 traffic is exploitable → Enforce firewall rules.
– Threat intelligence integration is critical → Leverage Honeywell Cyber Insights.
Expected Output:
- A hardened OT environment with restricted USB access.
- Real-time ICS traffic monitoring via Wireshark/SIEM.
- Compliance with NIST/ISA/IEC 62443 using Honeywell Cyber Watch.
Prediction
By 2026, OT attacks will shift from ransomware to sabotage-driven campaigns, requiring AI-powered anomaly detection in ICS networks.
