A New Segmentation Method for Integrated ICS (Short Paper)

International audienceThe paper presents a new segmentation method for Integrated ICS (Industrial Control Systems) with Corporate system. This new method aims at simplifying security zones identification by focusing only on the system's aspects that are really relevant for segmentation taking into account the system's constraints. Multiple research works have studied IICS (Inte-grated ICS) segmentation but their solutions are unfortunately not generic enough and do not sufficiently take into account all of the Integrated ICS specificity. Our new method tries to address the problem more efficiently by providing realistic and pragmatic answers to the issue while remaining sufficiently generic to be applied to different types of Integrated ICS
