In windows driver development, we have minifilters to protect valuable files in its pre write/setfileinformation callbacks, to protect files for example against ransomware attacks.
My question is, what is the equivelant of this in linux? I assume its only possible in kernel mode, but if it is also possible in the user mode of linux, please also let me know.
Basically the question is: is there any callback available in linux for pre-write and pre-setfileinformation of files, either user-mode or kernel-mode?
And does it provide the same,less, or more functionality compare to the windows minifilters for file protection?
