the network and interactively.
NTFS Permissions
NTFS permissions give both network users and interactive users fine-grained access control over
folders and files. Unlike share permissions, which can be configured only on a shared folder,
NTFS permissions can be configured on folders and files. By default, when permissions are con-
figured on a folder, subfolders and files in that folder inherit the permissions. However, inherited
permissions can be changed when needed, making it possible to have different permission set-
tings on files in a folder.
Permissions and permission inheritance, as they pertain to Active Directory objects, were
discussed in Chapter 4, and they work much the same way when applied to NTFS folders and
files. Perhaps the biggest difference between setting Active Directory and NTFS permissions is
that there's no Delegation of Control Wizard for NTFS folders. To view or edit permissions on
an NTFS folder or file, you simply access the Security tab of the object's Properties dialog box.
Unlike share permissions, which have only three permission levels, NTFS folders have six
standard permissions, and NTFS files have five. Folders also have 14 special permissions, and
files have 13. Special permissions aren't completely separate from standard permissions, how-
ever. Each standard permission is really a grouping of special permissions, as you see later.
NTFS standard permissions for folders and files are as follows (see Figure 6-9):
Read —Users can view file contents, copy files, open folders and subfolders, and view file
attributes and permissions. However, unlike the Read permission in share permissions, this
permission doesn't allow users to run applications or scripts.
Read & execute —Grants the same permissions as Read and includes the ability to run
applications or scripts. When this permission is selected, List folder contents and Read are
selected, too.
List folder contents —This permission applies only to folders and grants the same permis-
sion as Read & execute. However, because it doesn't apply to files, Read & execute must
also be set on the folder to allow users to open files in the folder.
