Read the ntfs-3 man page.
Take a look at the man page for ntfs-3g, the section on
Access Handling and Security:
From the ntfs-3g man page:
------------------------------------------------------------
Access Handling and Security
By default, files and directories are owned by the effective
user and group of the mounting process, and ev‐
erybody has full read, write, execution and directory browsing
permissions. You can also assign permissions
to a single user by using the uid and/or the gid options
together with the umask, or fmask and dmask options.
Doing so, Windows users have full access to the files created by
ntfs-3g.
But, by setting the permissions option, you can benefit from the
full ownership and permissions features as
defined by POSIX. Moreover, by defining a Windows-to-Linux
user mapping, the ownerships and permissions are
even applied to Windows users and conversely.
If ntfs-3g is set setuid-root then non-root users will be also
able to mount volumes.
------------------------------------------------------------
You use the defaults option when mounting. I do not know how that
affects access and security for ntfs-3g. I would suggest either using
uid and gid options when mounting instead, or using the
usermapping file that maps Windows users to Debian users.
You need to check which user under Windows owns those folders, which Windows
users have write access to those folders, etc.
As mentioned in the man page, there is a way to map Windows users to
Debian 11 users using the default .NTFS-3G/UserMapping file or a
custom usermapping file with the usermapping mount option.
I used this feature a long time ago, and the format for the usermapping
file is documented in the ntfs-3g man page.
As is said at the beginning of this reply, read the ntfs-3g man page!
HTH,
Chuck
