Script: Set NTFS Permissions on a Folder via PowerShell

Scenario: You want to set NTFS permissions on a folder via Powershell. You want the permissions to inherit down to SubFolders and files as well.

Scriptlet:

$folder = "\FileSvr1filestest12345"
$user = "DomainJdoe"

# Get the ACL for an existing folder
$existingAcl = Get-Acl -Path $folder

# Set the permissions that you want to apply to the folder
$permissions = $user, 'Read,Modify', 'ContainerInherit,ObjectInherit', 'None', 'Allow'

# Create a new FileSystemAccessRule object
$rule = New-Object -TypeName System.Security.AccessControl.FileSystemAccessRule -ArgumentList $permissions

# Modify the existing ACL to include the new rule
$existingAcl.SetAccessRule($rule)

# Apply the modified access rule to the folder
$existingAcl | Set-Acl -Path $folder
