Permission Inheritance for Files and Folders

By default, when you add a folder or file to an existing folder, the folder or file inherits the permissions of the existing folder. For example, if the Domain Users group has access to a folder and you add a file to this folder, members of the Domain Users group will be able to access the file. Inherited permissions are automatically assigned when files and folders are created.

When you assign new permissions to a folder, the permissions propagate down and are inherited by all subfolders and files in the folder and supplement or replace existing permissions. If you add permissions on a folder to allow a new group to access a folder, these permissions are applied to all subfolders and files in the folder, meaning the additional group is granted access. On the other hand, if you were to change the permissions on the folder so h that, for instance, only members of the Engineering group could access the folder, these per- ^

missions would be applied to all subfolders and files in the folder, meaning only members of the Engineering group would have access to the folder, its subfolders, and its files. °

Inheritance is automatic. If you do not want the permissions of subfolders and files within folders to supplement or replace existing permissions, you must override inheritance starting with the top-level folder from which the permissions are inherited. A top-level folder is referred to as a parent folder. Files and folders below the parent folder are referred to as child files and folders. This is identical to the parent/child structure of objects in Active Directory.

Changing Shaded Permissions and Stopping Inheritance

If a permission you want to change is shaded, the file or folder is inheriting the permission from a parent folder. To change the permission, you must do one of the following:

• Access the parent folder and make the desired changes. These changes will then be inherited by child folders and files.

• Select the opposite permission to override the inherited permission if possible. In most cases, Deny overrides Allow, so if you explicitly deny permission to a user or group for a child folder or file, this permission should be denied to that user or group of users.

• Stop inheriting permissions from the parent folder and then copy or remove existing permissions as appropriate.

To stop inheriting permissions from a parent folder, right-click the file or folder in Windows Explorer, and then select Properties. In the Security tab of the Properties dialog box, click Advanced to display the Advanced Security Settings dialog box shown in Figure 21-17.

Allow inheritable permissions from the parent to propagate to this object and all child objects. Include these with entries explicitly defined here.

Clear Allow Inheritable Permissions From The Parent To Propagate To This Object. As shown in Figure 21-18, you now have the opportunity to copy over the permissions that were previously applied or remove the inherited permission and only apply the permissions that you explicitly set on the folder or file. Click Copy or Remove as appropriate.

Selecting this option means that the parent permission entries that apply to child objects will no longer be applied to this object.

-To copy the permission entries that were previously applied from the parent to this object, click Copy.

-To remove the permission entries that were previously applied from the parent and keep only those permissions explicitly defined here, click Remove.

-To cancel this action, click Cancel.

Resetting and Replacing Permissions

Another way to manage permissions is to reset the permissions of subfolders and files within a folder, replacing their permissions with the current permissions assigned to the folder you are working with. In this way, subfolders and files get all inheritable permissions from the parent folder and all other explicitly defined permissions on the individual subfolders and files are removed.

To reset permissions for subfolders and files of a folder, right-click the file or folder in Windows Explorer, and then select Properties. In the Security tab of the Properties dialog box, click Advanced to display the Advanced Security Settings dialog box shown previously in Figure 21-17.

Select Replace Permission Entries On All Child Objects With Entries Shown Here, and click OK. As shown in Figure 21-19, you will see a prompt explaining that this action will remove all explicitly defined permissions and enable propagation of inheritable permissions. Click Yes.
