I have been asked to set up a file server on a windows OS not using any active directory stuff. Just a simple file sharing stuff in which: Person A will be the only one to put a file into Folder A but will also be able to get files from Folder B & C. And the same will hold for person B and person C - a folder can only be edited by a particular person/group but all can access and get files from it. My question is how will one implement this securely, making sure person B cannot edit files in folder A for example.
File system permissions: ------------------------ Grant read access on the parent folder to "Authenticated Users" or "Everyone", and have the subfolders inherit that ACL. Grant full control on each immediate child folder to just the user who is supposed to be able to write to it. Share permissions: ------------------ Share the parent folder and grant full control to "Authenticated Users" or "Everyone". Actual access is controled by file system permissions anyway, so this setting only has marginal impact on security. The above can be achieved with both Windows or Samba. On Windows I'd suggest to also enable access-based enumeration, so that a user will only see files/folders he can actually access. Note that without an AD you'll need to create all users on the file server.
