Larger scale and complexity industrial control networks present risks, and cybersecurity needs that usually cannot be met by applying a traditional segmentation model. Factors such as the presence of critical obsolete equipment, equipment managed by third parties or the increased presence of IoT technologies that require external connections, are motivating the adoption of more advanced architectures when applying the principle of defense in depth.Proper segmentation can be a fundamental aspect in preventing attacks, especially in their propagation to essential and critical production assets. It is also important to adapt to the environment to be segmented. It is a common mistake to try to segment networks based on concepts and schemes like the IT environment.This article will present some new network models and tips to work on a correct segmentation in an environment where different components are involved (OT, IIoT, IT, IoT).
