The latest trend? AI for OT security.
- AI will detect every anomaly!
- AI will simplify asset management!
- AI will automate risk assessments!
Sounds great—until you look under the hood.
- AI can’t learn what isn’t documented. If your control network has 15 years of undocumented changes, AI is just guessing or hallucinating.
- AI doesn’t understand the operational context. It might flag a spike in traffic but has no clue if it’s a normal startup sequence or an actual attack.
- AI still needs a human in the loop. Risk decisions aren’t binary—context matters. A bad AI call in IT means a false positive. In OT, it could mean shutting down production.
The problem isn’t AI. It’s the belief that technology alone can fix security. Vendors have sold “silver bullet” solutions for decades—firewalls, anomaly detection, and asset discovery. Now, AI is the latest magic fix. But no tool replaces strategy, process, and execution.
You Should Know:
Here are some practical commands and tools to enhance OT security:
1. Network Monitoring with Wireshark:
sudo wireshark
Use Wireshark to analyze network traffic and identify anomalies.
2. Asset Discovery with Nmap:
nmap -sP 192.168.1.0/24
Scan your network to identify connected devices and their status.
3. Log Analysis with Grep:
grep "error" /var/log/syslog
Search logs for errors or unusual activity.
4. Firewall Configuration with UFW:
sudo ufw allow 22/tcp sudo ufw enable
Configure a firewall to restrict unauthorized access.
5. Patch Management with APT:
sudo apt update && sudo apt upgrade -y
Keep your systems updated to mitigate vulnerabilities.
6. Backup with Rsync:
rsync -av /source/directory /backup/directory
Regularly back up critical data to ensure recovery in case of an incident.
7. Process Monitoring with HTOP:
htop
Monitor system processes in real-time to detect suspicious activity.
8. File Integrity Checking with AIDE:
sudo aide --check
Use AIDE to monitor file integrity and detect unauthorized changes.
What Undercode Say:
AI is a powerful tool, but it’s not a standalone solution for OT security. A robust security program requires a combination of knowledge, training, planning, and engineering processes. Focus on understanding your OT systems, documenting changes, and empowering your team with the right skills. Use tools like Wireshark, Nmap, and AIDE to monitor and secure your environment. Remember, security is an execution game—strategy and process matter more than any single technology.
