If the people accessing the systems also runs at root you cant protect the files from them since you as root can change the permissions to anything you want.

But there is ways to even protect the systems from root. But for that you have to install som accesscomtrol systems like Grsecurity. http://www.grsecurity.org. Which maybe is a little overkill.
