Is there integrity control in the CIFS/SMB protocol?

Question

linux

Or in other words, can files break when uploading to a shared folder or back, if there are problems with network cards, switches, routers, or just a bad cable? I know there are basic checksums in IP/TCP, but that's not the point. I also know that SMB itself has SecuritySigning technology, but I didn’t go into details (and it is disabled by default), is this checksums or just protection against MITM attacks?

Answer 2

From personal experience, files fought on the ball, and small ones were copied without problems, and large ones fought, a defective memory bar was accidentally discovered. Comp-r worked fine without hangups.
