For my small home network I've found that it is easiest to setup network shares with share permissions set to Everyone: Full Control share permission and then configure the NTFS permissions according to my desires. Trying to setup Share and NTFS permissions to match always seemed to cause problems and was a pain due to extra work.
My question is, could this setup result in any security issues such as someone accessing files they shouldn't? Is relying on the NTFS permissions sufficient to secure access to the files?
A couple examples of how things are setup:
This share contains movies, music, etc. Everyone should be able to read from here, but only I should be able to write/delete. The share is configured for full control to everyone. NTFS permissions grant read to the Users group, and Full Control to my user.
\\work-pc\projects and \\laptop\projects
These shares let me transfer work projects between my desktop and laptop. Only I should be able to access anything in these folders. Share permissions are setup for Full Control to everyone. NTFS permissions grant full control to my account. Other accounts / the users group are not listed.
The network consists of a mix of windows 10 / windows 7 machines and my android phone/tablet. Password protected sharing is turned off on all the windows machines.
