Advantages and disadvantages of dual (DMZ) The main advantage of dual (DMZ) is that it provides protection not only from external hackers, it also protects from internal hackers. This means that an intrusion detection system (IDS) or intrusion prevention system (IPS) within a DMZ could be configured to block any traffic other than Hypertext Transfer Protocol Secure (HTTPS) requests to the Transmission Control Protocol (TCP) port 443. They are used to isolate a company's outward-facing applications from the corporate network. Companies even more concerned about security can use a classified militarized zone (CMZ) to house information about the local area network. In case of not doing so, we may experience a significant drop in performance as in P2P programs and even that they do not work. The key to VPN utilization in a DMZ focuses on the deployment of the VPN in the demilitarized zone (DMZ) itself. The lab first introduces us to installation and configuration of an edge routing device meant to handle all internal network traffic between devices, and allow access out to an external network, in our case the Internet.
