SetACL Commands

SetACL

SetACL is a tool for manipulating permissions, or, to be more exact, security descriptors (SDs). SDs are used on operating systems based on Windows NT to control access to securable objects.

SetACL is a tool for manipulating permissions.


SetACL is relatively feature complete and bug free. SetACL has been fast and stable from the very beginning!
SetACL can set permissions on:

• Local or remote directories
• Local or remote files
• Local or remote printers
• Local or remote registry keys
• Local or remote Win32 services
• Local or remote network shares

The following special features distinguish SetACL from similar programs:

• Use all special permissions of Windows 2000 in the file system and in the registry.
• Block the inheritance from the parent object while copying the ACL from the parent object or clearing it.
• Specify how permissions are inherited to child objects: container, object or container + object.
• Set permissions for any type of user or local / domain local / global / universal group.
• Set permissions on any machine; it does not matter whether the target machine is in a trusted domain, an independent domain or a workgroup.
• Use wildcards in object names (only works in the file system).
• Recursively set permissions on any sub-object in the file system and in the registry.
• Set, grant, deny or revoke permissions.

Remarks
The “object name” parameter:

• Files/directories: Can be a relative path (“filename”), absolute path (“c:\dirname”) or a UNC name (“\\machine\share\dirname“).

• Printers: Can be a local (“printername”) or a remote printer (“\\machine\printername“)

• Registry key: Can be a local (“MACHINE\MyKey”) or a remote registry key (“\\machine\MACHINE\MyKey”).The hive keys must be specified like this: “CLASSES_ROOT”, “CURRENT_USER”, “MACHINE”, “USERS”.

• Service: Can be a local (“servicename”) or a remote service (“\\machine\servicename“).

• Share: Can be a local or remote network share. Always specify: “\\machine\share“.  The “action” parameter:

• ”/grant”: Creates a new access-allowed ACE that combines the specified rights with any existing rights of the trustee. The new ACE replaces any existing access-allowed ACE for the trustee. The program also modifies or deletes any existing access-denied ACE for the trustee that denies the specified rights.

• ”/set”: Similar to /grant except that the new access-allowed ACE allows only the specified rights, discarding any existing rights. This flag also removes any existing access-denied ACE for the trustee.

• ”/deny”: Creates a new access-denied ACE that replaces any existing access-denied ACE for the trustee. The new ACE denies the specified rights in addition to any currently denied rights of the trustee. The program also modifies or deletes any existing access-allowed ACE for the trustee that allows the specified rights.

• ”/revoke”: Removes any existing ACEs for the specified trustee. The program ignores the rights specified.

• The action parameters can be abbreviated by using only the first letter, ie. “/g” instead of “/grant”. The “trustee” parameter:

• This is the user or group you want to set the permission for.

• It can be a any type of local or domain user or group (local/domain user, local group, domain local group, global group or universal group).

• Always use the format ‘machine\user’ or ‘domain\user’. If you want to set permissions for a local group on your local machine, please omit the ‘machine\’ part.

• You can use predefined groups, like “EVERYONE” or “GUEST”. If you do this, a machine name should not be specified.

• The following special names can be used:

o ”CREATOR GROUP”: This is used in conjunction with inheritance. When a new object is created, the system replaces this SID with the primary group SID of the user who created the object.
o ”CREATOR OWNER”: This is used in conjunction with inheritance. When a new object is created, the system replaces this SID with the SID of the user who created the object.
o ”CURRENT_USER”: Indicates the owner of the calling thread or process.

• If the optional parameter “/sid” is used the trustee is expected to be a SID (security ID). This can be very useful if you want to set permissions for generic (built-in) users or groups in a language independent way. Example: on an english machine the administrators group is called “Administrators”; on a german machine it is called “Administratoren”. Hint: the SIDs of generic users/groups are always the same, regardless of OS type or language. A list of generic SIDs can be found here.
The “permissions” parameter:

• The permissions you can set on files, directories and registry keys correspond to the standard and special permissions of Windows 2000.

• I added a set of permissions of my own, “/profile”, which sets the permissions needed for a user profile folder on Windows 2000, which are “change” + “set permissions”.

• The permissions you can set on printers, network shares, services and correspond to the standard permissions of Windows 2000.
The “inheritance” parameter:

• Use this with extreme caution, especially on production machines!

• The correct (standard) inheritance flags are always set for you. If you need to, you can use this parameter to specify special, non-standard inheritance flags.

• If you set permissions on a container (for example, a directory) that contains sub-containers and/or objects, permissions are propagated down the tree.

• The following flags can be used:
o ”/cont_obj_inh”: Both container and noncontainer objects that are contained by the specified container inherit the ACE in addition to the container specified.
o ”/cont_inh”: Other containers that are contained by the specified container inherit the ACE in addition to the container specified.
o ”/obj_inh”: Noncontainer objects contained by the specified container inherit the ACE in addition to the container specified.
o ”/inh_only_obj”: The ACE does not apply to the specified container to which the ACL is applied, but objects contained by the specified container inherit the ACE.
o ”/inh_only_cont”: The ACE does not apply to the specified container to which the ACL is applied, but containers contained by the specified container inherit the ACE.
o ”/inh_only_cont_obj”: The ACE does not apply to the specified container to which the ACL is applied, but containers and objects contained by the specified container inherit the ACE.
o ”/no_prop_inh”: The ACE is not propagated down to lower level objects/containers.
The “inherit from parent” parameter:

• ”yes”: This object inherits permissions from its parent objects. This is the normal setting for any type of object. If you do not specify this optional argument, “yes” is always assumed.

• ”no_copy”: This object blocks permissions from its parent objects. The permissions from the parent object are copied to the object specified and then the permissions are set.

• ”no_dont_copy”: This object blocks permissions from its parent objects. The permissions from the parent object are NOT copied to the object specified which results in an ACL that contains only the permissions set with SetACL.
The “recursion” parameter:

• (Only for registry keys and directories) Walk down the tree and set permissions on every key/directory/file. This is only needed on NT4 and in special cases since Windows 2000 progagates permissions down the tree all by itself.

• ”cont_obj”: Recursively set permissions on every container (registry keys and directories) and object (files).

• ”cont”: Recursively set permissions ONLY on containers (registry keys and directories).

• ”obj”: Recursively set permissions ONLY on objects (files).
The “/sid” parameter:

• If the optional parameter “/sid” is used the trustee is expected to be a SID (security ID). This can be very useful if you want to set permissions for generic (built-in) users or groups in a language independent way. Example: on an english machine the administrators group is called “Administrators”; on a german machine it is called “Administratoren”. Hint: the SIDs of generic users/groups are always the same, regardless of OS type or language. A list of generic SIDs can be found here.
The “/silent” parameter:

• If the optional parameter “/silent” is used no output will be generated if the number of parameters passed to the program is correct. This can be useful if SetACL is used in batch files or from scripts. Successful execution can be checked using the return value which is always set.
