WikiServer - Securing the Wiki

There are a number of settings and tweaks that can save you grief while maintaining your wiki.

Item #1 try hard not to be bored during the install...

Item #2 disallow edits

by anyone who is not logged in with a valid account. This is done by choosing "Authorised editors only" as the User rights profile.

The default, Open wiki, is pretty much asking for spam & chaos...

Item #3 account creation control.

A good starting point to manage account creation (albeit manually...) is to add $wgGroupPermissions['*']['createaccount'] = false; to your LocalSettings.php (which is hiding out in /etc/var/html/wiki on a stock-standard install)

Using this method, it takes an Administrator to actually create a new account.

Further thoughts

There are a large number of further items in the documentation, including plugins & add-ons to enhance security.

The 3 items listed here are a good starting point tho.
