In short: a very good understanding of file and folder permissions. There is no clear answer to this question. Folder and file permissions are very complicated. You can individually control folder and file permissions by right clicking on the folder/file, select properties, click on security and click on 'Edit...'. Be aware that this can have far reaching consequences. I suggest you go to http://technet.microsoft.com/en-us/ and learn about file and folder permissions. It is not easy and very tricky.
