Configuring Data Access and Protection - NTFS Permissions

4 important questions on Configuring Data Access and Protection - NTFS Permissions

The 2 different NTFS ACL (Access Control Lists)


DACL (Discretionary Access Control List)
- For controlling access to different resources.

SACL (System Access Control List)
- For controlling auditing of different resources/sources.

Each list has one or more entries.

How does creator / owner access work within NTFS


The creator / owner controls access to the file or folder, but this can be overridden.

The child folders inherit the permissions by default, but this can also be overridden.

"Deny" beats "Allow", however a child folder "Allow" can override a parent folder "Deny".

How does move or copy change permissions on a file or folder


If a folder is moved to a different folder on the same volume, it will keep its permissions.

In all other cases (move or copy) it automatically inherits the permissions from the new parent folder.
