NTFS special permissions (Windows NT)


Definition of NTFS Special Permissions (Windows NT) in Network Encyclopedia.

What are NTFS special permissions (Windows NT)?

NTFS Special Permissions are individual permissions granted or denied when NTFS file system standard permissions are not sufficiently granular for specific security purposes.

The special permissions available are the same whether you are securing files or folders, with the exception that when you secure a directory you have the additional option of leaving access unspecified instead of assigning a specific set of special permissions.

How It Works

By selecting different combinations of special permissions, you can create custom sets of permissions for special purposes. In most cases, however, NTFS standard permissions are sufficient for securing files and folders. To use special permissions you must be the object’s owner, have full control of the object, or be a member of the Administrators system group. For information on which sets of special permissions comprise the various standard permissions, see the entry on NTFS permissions (Windows NT).

NOTE
