They protect organizations sensitive data, systems, and resources by keeping internal networks separate from systems that could be targeted by attackers. If we require L2 connectivity between servers in different pods, we can use a VXLAN overlay network if needed. Improved Security. Some of the most common of these services include web, email, domain name system, File Transfer Protocol and proxy servers. This implies that we are giving cybercriminals more attack possibilities who can look for weak points by performing a port scan. Others The use of a demilitarized zone (DMZ) is a common security measure for organizations that need to expose their internal servers to the Internet. A highly skilled bad actor may well be able to breach a secure DMZ, but the resources within it should sound alarms that provide plenty of warning that a breach is in progress. Companies even more concerned about security can use a classified militarized zone (CMZ) to house information about the local area network. I think that needs some help. The main purpose of using a DMZ network is that it can add a layer of protection for your LAN, making it much harder to access in case of an attempted breach.
