The Role DMZ in Server Environment In any situations that demand the use of internet interface, security becomes paramount, as there are several risks involved in using the internet through unprotected servers. DMZ is a term derived from the term ‘Demilitarized Zone’ that denotes a perimeter network that links an organization’s servers to untrusted outside networks. Usually, a DMZ comes between the VLAN and the servers of a particular organization (Shinder 191). This essay discusses the features and functionality of the ‘Demilitarized Zone’ (DMZ) in a server environment.

A DMZ operates in such a manner that it acts as an external layer that shields the LAN against unwarranted access by other internet users. This normally occurs during communication where the DMZ does not allow an organizations email and web servers to be accessed by unauthorized individuals. It does so by only allowing the access to the equipment in the stead of the network (Shinder 191).Under ordinary network such hosts as email, web, Local Area Network, and Domain Name System are vulnerable to external attack by internet users.

Therefore, the DMZ provides limited connectivity to such hosts so that they only have access to the DMZ and not external networks. Manu organizations install the internal proxy in their DMZ so that users without the proxy login cannot have access to the network. In addition, the proxy filters the content of the central web. On the other hand, the organization may opt to use a reverse proxy that allows indirect access to the external users. The application layer firewall enables this by focusing on the nature of the network traffic rather than regulating access to the UDC and TCP ports (Shinder 191).
