Actually the AbuseFilter extension males it possible to do a temp lockdown on your wiki incase of anon vandals (Its best to turn it off after an hour) it also allows you to restrict uploading, creating pages, etc by user rights group. Although it is recomended that you keep it as open as possible and only use filters like this in a crisis.
