Controlling permissions inheritance

Why prevent propagating permissions?

By default, permissions that you grant to a parent folder are inherited by the subfolders and files that are contained in the parent folder. When you create files and folders, and when you format a partition with NTFS, Windows Server 2003 automatically assigns default NTFS permissions.

You can prevent subfolders and files from inheriting permissions that are assigned to the parent folder. When you prevent permissions inheritance, you can either:

■ Copy inherited permissions from the parent folder. - or -

■ Remove the inherited permissions and retain only the permissions that were explicitly assigned.

The folder at which you prevent permissions inheritance becomes the new parent folder, and the subfolders and files that are contained in it inherit the permissions assigned to it.

Permissions inheritance simplifies how permissions for parent folders, subfolders, and resources are assigned. However, you may want to prevent inheritance so that permissions do not propagate from a parent folder to subfolders and files.

For example, you may need to keep all Sales department files in one Sales folder for which everyone in the Sales department has Write permission. However, for a few files in the folder, you may need to limit the permissions to Read. To do so, prevent inheritance so that the Write permission does not propagate to the files contained in the folder.
