Share Permissions vs Security

I am sure that this question has been asked thousands of times, but I would
like to re-ask it. I believe I know that share permissions apply to a
share, and that NTFS permissions apply to files and folders.

When I look at the Properties for a share, why do I even see the NTFS
permissions, which I gather is the last tab labelled "Security"?

If we're working in the context of shares, why do we also see NTFS
permissions in the properties?

Sorry if this question sounds odd. I am just trying to get a broader
understanding.

Hello Buck,

They are different, share permissions are for the shared itself and will
win, regardless of which NTFS permissions are set. So if you set the share
permissions to read-only and the NTFS permissions to a security group to
Full control, they still have read-only access.

So share and NTFS permissions must always be set as a combination.

Thanks for the response. But what do the NTFS permissions apply to? Is it
the folder that underlies the share?

Hello news.eternal-september.org,

This is depending on which folder you configure the NTFS settings.
