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https://www.debian.org/doc/manuals/securing-debian-manual/index.en.html They might have some sections that are a little outdated.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. Regards, -Roberto -- Roberto C. Sánchez
