Operating system (OS) support

We aim to ensure the security and integrity of the Departmental network and wider CUDN by encouraging the installation and use of modern operating systems which are supported by maintenance contracts (where applicable) and which may be kept up-to-date with security patches.

It is assumed that all operating systems have had patches and service packs applied. Some operating systems or versions thereof cannot be patched and made secure so do not connect machines running them to the Departmental network.

This following list is not intended to be exhaustive. If you have a particular need or requirement to run an OS that is not listed, please contact the Computer Officers preferably by email to to discuss the situation.
