For example, a cloud service like Microsoft Azure allows an organization that runs applications on-premises and on virtual private networks VPNs to use a hybrid approach with the DMZ sitting between both. This method can also be used when outgoing traffic needs auditing or to control traffic between an on-premises data center and virtual networks.
Further, DMZs are proving useful in countering the security risks posed by new technology such as Internet-of-Things IoT devices and operational technology OT systems, which make production and manufacturing smarter but create a vast threat surface. A DMZ provides network segmentation to lower the risk of an attack that can cause damage to industrial infrastructure.
It creates a hole in the network protection for users to access a web server protected by the DMZ and only grants access that has been explicitly enabled.
Check out the Fortinet cookbook for more information on how to protect a web server with a DMZ. A DMZ, which is short for a demilitarized zone, is a perimeter network that enables organizations to protect their internal networks. It enables organizations to provide access to untrusted networks, such as the internet, while keeping private networks or local-area networks LANs secure.
A DMZ is usually used to store external-facing resources, servers, and services. The DMZ network itself is not safe. It enables hosts and systems stored within it to be accessible from untrusted external networks, such as the internet, while keeping other hosts and systems on private networks isolated. A DMZ provides an extra layer of security to an internal network.
It restricts access to sensitive data, resources, and servers by placing a buffer between external users and a private network. Other benefits include access control, preventing attackers from carrying out reconnaissance of potential targets, and protecting organizations from being attacked through IP spoofing.
A DMZ can be used on a router in a home network. Some home routers also have a DMZ host feature that allocates a device to operate outside the firewall and act as the DMZ.
All other devices sit inside the firewall within the home network. A gaming console is often a good option to use as a DMZ host. It ensures the firewall does not affect gaming performance, and it is likely to contain less sensitive data than a laptop or PC.
