Thread:Project:Forum/Can Mediawiki be used on private servers

I work in a company and for our group we have a private server for the 10 of us, We are currently using Twiki on this server but I'd like to switch to MediaWiki, the information on this wiki are mostly confidential so it's important only people who can login to our server can view this wiki. Can mediawiki be installed on an intranet?

right now our address is http:our-wiki/twiki/bin/view/Main

I searched intranet and servers and I think there was only 1 thread regarding it and it was not really answered.
