Description: Value chain security in the context of IoT security refers to the practice of ensuring that all parts of the supply chain, from production to delivery, are protected against various threats. This includes the protection of devices, networks, and data used in the Internet of Things (IoT). As more devices connect to the Internet, the attack surface expands, making value chain security crucial. Key features of this security include device authentication, data encryption, continuous monitoring, and vulnerability management. The relevance of this practice lies in the growing dependence of businesses on IoT technologies to optimize processes, improve efficiency, and offer new services. Without adequate security in the value chain, organizations expose themselves to significant risks, such as data theft, operational disruptions, and reputational damage. Therefore, implementing robust security measures throughout the supply chain is essential to ensure the integrity and trustworthiness of IoT systems.
