Network micro-segmentation involves dividing an industrial network into small, isolated
zones based on functional requirements. This prevents a breach in one area, such
as a building management system, from spreading to more critical assets like a water
treatment process. By enforcing security policies at the individual asset level,
organisations can create granular boundaries that block lateral movement by attackers.
