## DESCRIPTION

Adds an access control entry (ACE) to an object such as a file or folder. NTFSSecurity allows you to apply basic permission groups (read, read/write, full) or advanced permissions that allow you to get granular with the permissions. See the below table for how the basic permissions map to the advanced permissions, and how NTFSSecurity handles them.

## EXAMPLES

### Example 1

```PowerShell
PS C:\> Add-NTFSAccess -Path C:\Data -Account 'NT AUTHORITY\Authenticated Users' -AccessRights Read
