From Development to Deployment: Ensuring Secure Variable Frequency Drives Against Cyber Attacks (S12b)
Variable Frequency Drives (VFDs) are pivotal in the operational technology network of industrial operations, handling, processing, and transporting critical data. With the advent of Industry 4.0, and possibly even 5.0, the integration of various embedded devices into the enterprise network has become commonplace. The traditional air-gap that once isolated operational networks is now nearly obsolete, necessitating robust measures beyond mere network segmentation to safeguard manufacturing environments from cyber threats. An attacker could exploit vulnerabilities in an insecure device, potentially disrupting operations and compromising system safety. This talk investigates the methodologies and principles for constructing secure variable frequency drives and outlines best practices for creating secure components to foster a cyber-resilient manufacturing ecosystem that is deployment ready. Essential considerations for establishing a sustainable and replicable security program are examined, including the development of security requirements for ICT devices and their validation in accordance with industry-recognized standards 62443-4. The talk emphasizes four fundamental pillars: secure development practices, critical functions integrated into ICT devices, system-level compensating controls, and end-user responsibilities. Together, these form a comprehensive defense-in-depth strategy for secure system development, ensuring robust protection against cyber threats in industrial settings and compliance with evolving regulations. This talk contributes to the ongoing dialogue at the EU CyberActs conference on enhancing cybersecurity resilience in industrial operations.
