Open-Source OT Security: Cost-Effective Industrial Defense

🔒 Open-source tools can provide a cost-effective, flexible foundation for operational technology (OT) security in industrial environments. By combining passive asset discovery, protocol-aware inspection, IDS/IPS, centralized logging and vulnerability management, organizations can approximate many capabilities of expensive commercial offerings. Recommended components include Malcolm (with Zeek), Security Onion, ELK, Wazuh and OpenVAS, augmented by asset sources like NetBox.
