Feature: IIOT


as a consequence of cyberattacks that force them to shut down their plants, recall products and take other drastic measures to minimise the damage. Tese incidents can also expose data, leading to failed customer orders. To address these challenges, the Trusted Computing Group (TCG) is actively working to resolve vulnerabilities in IIoT systems and help the manufacturing sector establish comprehensive cyber resilience. Ensuring legitimacy is vital to prevent system downtime,


revenue loss, malfunctioning equipment and safety hazards. In response to the evolving threat landscape, the TCG has developed technologies, standards and specifications such as the Trusted Platform Module (TPM) and Device Identifier Composition Engine (DICE) to provide a foundation of trust for devices.


Establishing trust Te TPM is a hardware-based security feature that ensures a safe environment for storing and processing private data. A TPM enables users to safely store cryptographic keys and other sensitive


information while attesting the identity of soſtware, firmware and other elements running on a device. Within the industrial sector, it can establish trust in communications between devices and control systems found within a factory, protecting the integrity of the devices and the data. DICE offers the same capabilities as TPM, but it is more suitable


for smaller devices. Trough specifications like DICE, attributes that identify a device such as the manufacturer, model and serial numbers can safely be stored in a protected environment to reduce the risk of tampering.


Crucial effort As industries become increasingly shaped by IIoT, cyber resilience becomes crucial. Cyber threats can have real-world consequences, underscoring the importance of fortifying our defences. Te standards, specifications and technologies devised by the TCG


can bring manufacturers a sense of optimism and a strong line of defence against potentially disastrous attacks.
