Network segmentation
Dividing a network into walled-off zones to stop an attack from spreading everywhere.
Segmentation consists of dividing a network into separate zones, with controlled communications between them. That way, a hacked machine in one zone does not automatically give access to the rest, especially to sensitive systems. Taken down to each machine, it is called micro-segmentation, often linked to zero trust.
