Change permissions on a mount point

I have an assignment where I have to temporarily change the permissions on a mount point so that an ordinary user can't access it. Can anybody explain how to do this? I know that to change permissions you can use chmod. First I'm not sure which category "ordinary user" would fall under: owner, group, or other users. So I was thinking of just doing chmod 000 DIRECTORY_NAME. However, the permissions that I'm supposed to change are for one of the directories that comes up when I type the command df. However, all of these directories seem to have some sort of protection from changing their permissions. I hope it makes sense what I have to do. Any direction is greatly appreciated!
