What is a DMZ and what is it used for?
What is a DMZ and what is it used for? In computer networks, a DMZ, or demilitarized zone, is a physical or logical subnet that separates a local area network (LAN) from other untrusted networks — usually, the public internet. DMZs are also known as perimeter networks or screened subnetworks.
What is the difference between a DMZ and firewall?
Simply, a DMZ is portion of your network carved off and isolated from the rest of your network. A firewall is the appliance that creates that isolation, by restricting traffic both between the intranet and the DMZ and the DMZ and other networks it’s exposed to.
Is DMZ LAN or WAN?
In networking, the demilitarized zone (DMZ) is a buffer between the private LAN and the public Internet or WAN.
Are DMZ still used?
Though DMZ networks still offer a buffer between untrusted users and internal segments, the adoption of cloud services and virtualization means the in-house hosting of web servers isn’t as necessary.
