Briefly describe a demilitarized zone (DMZ).
What will be an ideal response?
A demilitarized zone (DMZ) is a network segment carved out by normally two routers-with firewalls-to provide a special place (a zone) on the network for any servers that need to be publicly accessible from the Internet. By definition, a DMZ uses network segmentation as a mitigation technique against attacks on the network. The most common DMZ design is to create a DMZ by using two routers with firewalls to create a perimeter network. With a perimeter network, the two firewalls carve out areas with different levels of trust.
