## What it is
A curated checklist for hardening GNU/Linux production systems, covering partitioning, bootloader, kernel, logging, users, filesystem, SELinux, and network security. It is a documentation-style reference with prioritized recommendations and summary checklists.

## Use cases
- harden a linux production server
- linux server security checklist
- secure bootloader and kernel settings
- configure selinux and auditd
- reduce attack surface of a linux system
- prepare a server for security audit

## When to choose
- you need a structured, prioritized reference for securing GNU/Linux systems
- you want a quick pre-deployment security review checklist
- you are a sysadmin learning hardening best practices

## When to avoid
- you need automated scanning or enforcement rather than a manual checklist
- you need hardening guidance for non-Linux platforms
- you need a tool that applies changes automatically

## Facets
- artifact type: learning-resource
- maturity: maintenance
- function: security, documentation
- domain: security, operating-systems, self-hosted
- platform: -
- tags: hardening, checklist, sysadmin, openscap, best-practices, devops, linux
