Perimeter, DMZ, and Segmentation
Last updated
What is Perimeter, DMZ, and Segmentation?
These are network security concepts that define how a network is structured to protect its assets. The perimeter is the outer defense line, controlling traffic entering and exiting the network. A DMZ (Demilitarized Zone) hosts publicly accessible services, isolating them from the internal network. Segmentation divides the network into smaller, isolated zones to limit the impact of a security breach.
