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.

| ListDirectory | ListDirectory | List Folder / Read Data |
| WriteData | CreateFile | Create Files / Write Data |

EXAMPLES
Example 1
PS C:\> Add-NTFSAccess -Path C:\Data -Account 'NT AUTHORITY\Authenticated Users' -AccessRights Read
The above command gives the read permissions to the built-in group of ‘Authenticated users’.
Example 2
PS C:\> Add-NTFSAccess -Path C:\Data -Account 'Contoso\Domain Admins' -AccessRights Full
The above command gives full permissions to the domain administrators group in the contoso active directory.
Example 3
PS C:\> Add-NTFSAccess -Path C:\Data -Account 'NT AUTHORITY\Authenticated Users' -AccessRights CreateFiles -AccessType Deny -AppliesTo ThisFolderOnly
The above command denies the the built-in group of ‘Authenticated users’ from creating files in this folder only.
PARAMETERS
-AccessRights
The AccessRights parameter designates the permissions to assign. There are individual permissions as well as ‘basic’ permissions. See the below table for how the basic permissions permissions map the the advanced permissions in the advanced security window.
Type: FileSystemRights2
Parameter Sets: (All)
Aliases: FileSystemRights
Accepted values: None, ReadData, ListDirectory, WriteData, CreateFiles, AppendData, CreateDirectories, ReadExtendedAttributes, WriteExtendedAttributes, ExecuteFile, Traverse, DeleteSubdirectoriesAndFiles, ReadAttributes, WriteAttributes, Write, Delete, ReadPermissions, Read, ReadAndExecute, Modify, ChangePermissions, TakeOwnership, Synchronize, FullControl, GenericAll, GenericExecute, GenericWrite, GenericRead
Required: True
Position: 3
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-AccessType
The AccessType parameter determines if the ACE allows or denies the permissions assigned.
Type: AccessControlType
Parameter Sets: (All)
Aliases: AccessControlType
Accepted values: Allow, Deny
Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-Account
The Account parameter defines the account or group to apply the permissions to.
Type: IdentityReference2[]
Parameter Sets: (All)
Aliases: IdentityReference, ID
Required: True
Position: 2
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-AppliesTo
The AppliesTo parameter defines where the permissions apply to and if there is any inheritance e.g “this folder only” or “this folder and subfolders”.
Type: ApplyTo
Parameter Sets: PathSimple, SDSimple
Aliases:
Accepted values: ThisFolderOnly, ThisFolderSubfoldersAndFiles, ThisFolderAndSubfolders, ThisFolderAndFiles, SubfoldersAndFilesOnly, SubfoldersOnly, FilesOnly, ThisFolderSubfoldersAndFilesOneLevel, ThisFolderAndSubfoldersOneLevel, ThisFolderAndFilesOneLevel, SubfoldersAndFilesOnlyOneLevel, SubfoldersOnlyOneLevel, FilesOnlyOneLevel
Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-InheritanceFlags
The InheritanceFlags parameter defines the inheritance of the ACLs.
ObjectInherit will apply the ACE to files and folders in the folder defined by the Path parameter.
ContainerInherit will apply the ACE to subfolders but not files.
There is more information on Microsoft Docs here
Type: InheritanceFlags
Parameter Sets: PathComplex, SDComplex
Aliases:
Accepted values: None, ContainerInherit, ObjectInherit
Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-PassThru
The PassThru parameter will return the new permissions as a table. If the PassThru parameter is omitted, there is no information returned if the operation was successful.
Type: SwitchParameter
Parameter Sets: (All)
Aliases:
Required: False
Position: Named
Default value: None
Accept pipeline input: False
Accept wildcard characters: False
-Path
The Path parameter defines where the file or container exists.
Type: String[]
Parameter Sets: PathComplex, PathSimple
Aliases: FullName
Required: True
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName, ByValue)
Accept wildcard characters: False
-PropagationFlags
The PropagationFlags parameter defines how the ACE is propagated to child objects.
Inherit specifies that the ACE is propagated only to child objects. This includes both folder and file child objects.
NoPropagateInherit specifies that the ACE is not propagated to child objects.
None specifies that no inheritance flags are set.
Type: PropagationFlags
Parameter Sets: PathComplex, SDComplex
Aliases:
Accepted values: None, NoPropagateInherit, InheritOnly
Required: False
Position: Named
Default value: None
Accept pipeline input: True (ByPropertyName)
Accept wildcard characters: False
-SecurityDescriptor
The SecurityDescriptor parameter allows passing an security descriptor or an array or security descriptors.
A security descriptor contains information about the owner of the object, and the primary group of an object. The security descriptor also contains two access control lists (ACL). The first list is called the discretionary access control lists (DACL), and describes who should have access to an object and what type of access to grant. The second list is called the system access control lists (SACL) and defines what type of auditing to record for an object.
Type: FileSystemSecurity2[]
Parameter Sets: SDSimple, SDComplex
Aliases:
Required: True
Position: 1
Default value: None
Accept pipeline input: True (ByPropertyName, ByValue)
Accept wildcard characters: False
