After cacls, xcacls.vbs, now we have icacls to set file and folder permissions.
Here are some practical examples.
Create a bunch of directories
md d:\apps md d:\profiles md d:\users
Share the directories. Note the offline caching; users are allowed to enable offline caching for their homedirs, other directories are disabled for offline caching.
net share apps=d:\apps /grant:everyone,FULL /CACHE:None net share profiles=d:\profiles /grant:everyone,FULL /CACHE:None net share users=d:\users /grant:everyone,FULL /CACHE:Manual
Now let’s script the ntfs permissions for the apps share:
– “(OI)(CI):F” means Full Control “This Folder, Subfolders and files”
– “(OI)(CI):M” means Modify “This Folder, Subfolders and files”
– “/inheritance:r” means remove all inherited ACL’s from parent
(OI) This folder and files
(CI) This folder and subfolders.
(OI)(CI) This folder, subfolders, and files.
(OI)(CI)(IO) Subfolders and files only.
(CI)(IO) Subfolders only.
(OI)(IO) Files only.
and the permission possibilities
perm is a permission mask and can be specified in one of two forms:
a sequence of simple rights:
N – no access
F – full access
M – modify access
RX – read and execute access
R – read-only access
W – write-only access
D – delete access
a comma-separated list in parentheses of specific rights:
DE – delete
RC – read control
WDAC – write DAC
WO – write owner
S – synchronize
AS – access system security
MA – maximum allowed
GR – generic read
GW – generic write
GE – generic execute
GA – generic all
RD – read data/list directory
WD – write data/add file
AD – append data/add subdirectory
REA – read extended attributes
WEA – write extended attributes
X – execute/traverse
DC – delete child
RA – read attributes
WA – write attributes
Here the discription of all the possible NTFS permissions
| Permission | Description |
|---|---|
| Traverse Folder/Execute File | For folders: Traverse Folder allows or denies moving through folders to reach other files or folders, even if the user has no permissions for the traversed folders. (Applies to folders only.) Traverse folder takes effect only when the group or user is not granted the Bypass traverse checking user right in the Group Policy snap-in. (By default, the Everyone group is given the Bypass traverse checking user right.)
For files: Execute File allows or denies running program files. (Applies to files only). Setting the Traverse Folder permission on a folder does not automatically set the Execute File permission on all files within that folder. |
| List Folder/Read Data | List Folder allows or denies viewing file names and subfolder names within the folder. List Folder only affects the contents of that folder and does not affect whether the folder you are setting the permission on will be listed. (Applies to folders only.)
Read Data allows or denies viewing data in files. (Applies to files only.) |
| Read Attributes | Allows or denies viewing the attributes of a file or folder, such as read-only and hidden. Attributes are defined by NTFS. |
| Read Extended Attributes | Allows or denies viewing the extended attributes of a file or folder. Extended attributes are defined by programs and may vary by program. |
| Create Files/Write Data | Create Files allows or denies creating files within the folder. (Applies to folders only).
Write Data allows or denies making changes to the file and overwriting existing content. (Applies to files only.) |
| Create Folders/Append Data | Create Folders allows or denies creating folders within the folder. (Applies to folders only.)
Append Data allows or denies making changes to the end of the file but not changing, deleting, or overwriting existing data. (Applies to files only.) |
| Write Attributes | Allows or denies changing the attributes of a file or folder, such as read-only or hidden. Attributes are defined by NTFS.
The Write Attributes permission does not imply creating or deleting files or folders, it only includes the permission to make changes to the attributes of a file or folder. In order to allow (or deny) create or delete operations, see Create Files/Write Data, Create Folders/Append Data, Delete Subfolders and Files, and Delete. |
| Write Extended Attributes | Allows or denies changing the extended attributes of a file or folder. Extended attributes are defined by programs and may vary by program.
The Write Extended Attributes permission does not imply creating or deleting files or folders, it only includes the permission to make changes to the attributes of a file or folder. In order to allow (or deny) create or delete operations, see Create Files/Write Data, Create Folders/Append Data, Delete Subfolders and Files, and Delete. |
| Delete Subfolders and Files | Allows or denies deleting subfolders and files, even if the Delete permission has not been granted on the subfolder or file. (Applies to folders.) |
| Delete | Allows or denies deleting the file or folder. If you do not have Delete permission on a file or folder, you can still delete it if you have been granted Delete Subfolders and Files on the parent folder. |
| Read Permissions | Allows or denies reading permissions of the file or folder, such as Full Control, Read, and Write. |
| Change Permissions | Allows or denies changing permissions of the file or folder, such as Full Control, Read, and Write. |
| Take Ownership | Allows or denies taking ownership of the file or folder. The owner of a file or folder can always change permissions on it, regardless of any existing permissions that protect the file or folder. |
| Synchronize | Allows or denies different threads to wait on the handle for the file or folder and synchronize with another thread that may signal it. This permission applies only to multithreaded, multiprocess programs. |
Example: icacls "d:\apps" /grant "domain admins":(OI)(CI)F /inheritance:r icacls "d:\apps" /grant "everyone":(OI)(CI)M /inheritance:r
On the profiles share, only the “domain admins” should be allowed to enter all “Folders, Subfolders and files” (hence the (OI)(CI):F) , everyone else should be able to to ready “this folder only”.
So without an combination of (CI) and/or (OI) it means “this folder only”
icacls "d:\profiles" /grant "domain admins":(OI)(CI)F /inheritance:r icacls "d:\profiles" /grant "everyone":R /inheritance:r
Upon creating a new user, the Domain Admin should manually create a profile folder for the user and add the user with appropriate rights.
The same goes for the users share containing the homedirectories of all users
icacls "d:\users" /grant "domain admins":(OI)(CI)F /inheritance:r icacls "d:\users" /grant "everyone":R /inheritance:r
Want to reset NTFS permissions from the command line? Use this syntax:
icacls “c:\users\jshipp\*” /q /c /t /reset
This is the same as using the GUI command:
Win7 – Replace all child object permissions with inheritable permissions from this object
WinXP – Replace permission entries on all child objects with entries shown here that apply to child objects
Warning: If you leave out the * then the jshipp folder will have the same permissions as the users folder, which is not what the GUI does, and probably not what you want, but it’s nice to know it’s possible.
Example takeown
takeown /f folder_name /r /d y
icacls folder_name /grant username_or_usergroup:F /t /q
