CSCS have a number of different networks in operation, many with specific purposes. Servers can be configured on most of our networks depending on what is required. Most servers and equipment will be connected to our standard internal network which allows access for all internal users, but is not directly accessible from the internet. Other options include a DMZ, the SDHS or a specific departmental network. We will discuss with you the options before commencing configuration of your server.

The Servers within the DMZ will be a PVLAN for isolation with access controlled by Firewall rulesrequire firewall rules for Egress and Ingress.

CSCS can allow servers hosted in our standard network to be accessed via the internet if required. For standard web access using HTTP (TCP 80) or HTTPS (TCP 443) we are able to publish the website through our web proxy appliances which offer a level of protection by scanning incoming web traffic.
