Industrial IoT devices play a critical role in modern manufacturing but often lack adequate security against tampering and runtime attacks. This paper proposes the use of Trusted Remote Attestation (TRA) as a lightweight and scalable method to verify the integrity of Industrial Internet of Things (IIoT) devices. By enabling remote validation of device state without requiring extensive hardware changes, TRA enhances trust and aligns with Zero Trust security principles. A practical implementation is discussed, demonstrating TRA's effectiveness in improving cybersecurity assurance for industrial environments. © 2025 IEEE.
