I would recommend starting here:

https://www.debian.org/doc/manuals/debian-handbook/security.en.html
https://www.debian.org/doc/manuals/securing-debian-manual/index.en.html

They might have some sections that are a little outdated.  But most of
the principles are still applicable, even if the precise implementation
is a little different as compared to a few years ago.
