![]() Get-ChildItem -Path C:\docs -Recurse | Get-NTFSAccess -Account 'corp\LMurkowski' -ExcludeInherited |Remove-NTFSAccess -PassThru The next command will remove the permissions for all nested objects in the folder for the given account (inherited permissions will be skipped): Remove-NTFSAccess -Path C:\DOCS -Account 'corp\LMurkowski' -AccessRights FullControl -PassThru To grant permissions only at the top folder level and not to change permissions on the nested objects (folder only), use this command:Īdd-NTFSAccess c:\docs\public -Account corp\LMurkowski -AccessRights Modify -AppliesTo ThisFolderOnly Use the -PassThru parameter to make the command display new ACLs after it is executed. By default, the NTFSSecurity cmdlets do not return any data. $acl.SetAccessRuleProtection($True, $True) # the first $True shows if the folder is protected, the second $True specifies if the current NTFS permissions have to be copied To disable folder inheritance from PowerShell: $targetrule = $rules | where IdentityReference -eq "corp\DSullivan" $rules = $acl.Access | where IsInherited -eq $false To remove the NTFS permission to access a folder for a user or a group: $rule = New-Object -TypeName -ArgumentList $perm $perm = $user, $Permiss, $InheritSettings, $PropogationSettings, $RuleType $InheritSettings = "Containerinherit, ObjectInherit" $Permiss = "Read, ReadAndExecute, ListDirectory" So to add the permissions on an object, you have to use the following complex script: The main problem of using Set-ACL is that the cmdlet is always trying to change the resource owner, even if you just need to change the NTFS permissions. Applies only to directories.To do it, the account must be the owner of the object and have Take Ownership privilege. ACE inherited by containers and objects from the parent container, but does not propagate to nested containers. ACE inherited from the parent container, but does not apply to the object itself. Containers in this parent container will inherit this ACE. Objects in this container will inherit this ACE. Inheritance rights may precede either form: The option is a permission mask that can be specified in one of the following forms:Ī sequence of simple rights (basic permissions):Ī comma-separated list in parenthesis of specific rights (advanced permissions): This command preserves the canonical order of ACE entries as: If you use a numerical form, affix the wildcard character * to the beginning of the SID. SIDs may be in either numerical or friendly name form. r - Disables inheritance and removes only inherited ACEs.d - Disables inheritance and copies the ACEs. ![]() Sets the inheritance level, which can be: Requires using with the parameter.Īpplies stored DACLs from to files in the specified directory. Replaces an existing SID ( sidold) with a new SID ( sidnew). Inheritance options for the integrity ACE may precede the level and are applied only to directories. :d - Removes all occurrences of denied rights to the specified SID.Įxplicitly adds an integrity ACE to all matching files.:g - Removes all occurrences of granted rights to the specified SID.Removes all occurrences of the specified SID from the DACL. ![]() An explicit deny ACE is added for the stated permissions and the same permissions in any explicit grant are removed. Not adding the :r, means that permissions are added to any previously granted explicit permissions.Įxplicitly denies specified user access rights. Permissions replace previously granted explicit permissions. Replaces ACLs with default inherited ACLs for all matching files. Stores DACLs for all matching files into an access control list (ACL) file for later use with /restore.Ĭhanges the owner of all matching files to the specified user.įinds all matching files that contain a DACL explicitly mentioning the specified security identifier (SID).įinds all files with ACLs that are not canonical or have lengths inconsistent with access control entry (ACE) counts. Performs the operation on a symbolic link instead of its destination. Performs the operation on all specified files in the current directory and its subdirectories.Ĭontinues the operation despite any file errors. Specifies the directory for which to display or modify DACLs. Specifies the file for which to display or modify DACLs. This command replaces the deprecated cacls command.
