we are working on a new Permission Concept. We created different Security Groups,depending on the Department.

For example:

Finance_List, Finance_Read, Finance_ReadWrite
Controlling_List, Controlling_Read, Controlling_ReadWrite
Planning_List, Planning_Read, Planning_ReadWrite

Now I am searching for a script to automate the process for setting GroupPermissions on specific Folders.

Example:
Folder Finance:
Disable Inheritance and then set new permissions and replace them to all files and subfolders: Group Finance_List (List Folder), Group Finance_Read (Read), Group Finance_ReadWrite (Modify)

CSV Example (Folderpath and the 3 GroupPermissions per Folder):

\\cifs\Finance;Finance_List;Finance_Read;Finance_ReadWrite

I have 300 securitygroups and 100 folders.

Any help would be much appreciated.

Thank You!

The following should get you what you need (make sure that the groups in your CSV match the name of the group in AD or it won't work correctly):

$Folders = Import-Csv "C:\Scripts\Folders.csv" -Delimiter ";" -Header "Path","List","Read","ReadWrite"

ForEach ($F in $Folders) {
    $ACL = Get-Acl $F.Path

    # Set the first parameter to $true to disable inheritance
    # Set the second parameter to $false if you don't want to retain a copy the permissions to this folder.
    # Set the second parameter to $true if you want to retain a copy of the inherited permissions.
    $ACL.SetAccessRuleProtection($true, $true)

    # 'ReadData' grants List Folder / Read Data
    $List = New-object System.Security.AccessControl.FileSystemAccessRule($F.List,"ReadData","Allow")
    $ACL.SetAccessRule($List)

    # 'ReadAndExecute' grants Traverse Folder / Execute File
    # 'Read' only grants List Folder / Read Data
    $Read = New-object System.Security.AccessControl.FileSystemAccessRule($F.List,"ReadAndExecute","Allow")
    $ACL.SetAccessRule($Read)

    $ReadWrite = New-object System.Security.AccessControl.FileSystemAccessRule($F.ReadWrite,"Modify","Allow")
    $ACL.SetAccessRule($ReadWrite)

    $ACL | Set-Acl $F.Path
}
