[CentOS] Tool to track files

Hi all,
Due to some reason, I will have to stop using Samba as our fileserver,
and instead replace it with SSH access only.
Users will be able to use WinSCP for it.

The question is, is there any tool to track files (what is new files,
deleted files by who, etc)?
In Samba I can do that. I don't know how if it's SSH access.

Thank you
Fajar.
