In an IIoT environment, data is collected from a multitude of OT edge devices and transmitted to an enterprise IT cloud for analysis and storage. The
insights gained from the processed data is then used by OT systems to implement appropriate actions. However, as cyberattacks are increasingly
targeting cloud networks, more and more enterprises are looking for ways to secure the computing infrastructure that collects and processes data for
their IIoT environments.
Industrial computers play a critical role in connecting industrial automation and control systems (IACS) to the cloud. Although this connectivity allows
formerly private systems to be accessible from practically anywhere, transmitting confidential data over untrusted networks requires greater attention to
network security and access to the edge devices. Consequently, more and more asset owners are becoming aware of the importance of cybersecurity
and starting to adopt IEC 62443-3-3 system security practices to protect their IIoT applications from threats, such as unauthorized access, tampering,
and data breaches.
