You can set the permissions up so that only certain people can access your page. I know you can do it through certain FTP clients, but I believe that next to your file names in the file manager, there is an icon that looks like a square slip of paper. If you hover over it, it should say 'permissions' or something to that effect. Click on it and you can edit the permissions for that file to only allow the webmaster or selected people to view.
those are file permissions and they dont stop people viewing your webpages
