restrict access to root /
I've just noticed that as any user on my CentOS box I can run
and I can access the root file system. Obviously accessing the other dirs within it isn't possible without the correct permissions, but this is a worry to me.
I don't know how to stop this, and because of the root (account) = root (filesystem) in the eyes of Google I can't find any help on this.
I appreciate your consideration on this, it seems pretty important (to me).
