You can set the Forum Permissions to not show that forum to your Registered Users usergroup.

Here is some more information about usergroup permissions on forums.

http://www.vbulletin.com/docs/html/forum_forum_permissions

You want to set the unregistered usergroup's permission for 'can view forum' to no and the registered usergroup's permission to yes.
