## What it is
An evolving, community-maintained how-to guide for securing a Linux server, covering SSH hardening, firewalls, intrusion detection, auditing, and system basics. It is a CC-BY-SA licensed documentation/tutorial resource rather than software.

## Use cases
- harden a fresh linux vps
- secure ssh with keys and 2fa
- set up ufw firewall and fail2ban
- learn linux server security best practices
- reduce attack surface of a self-hosted server
- guide for securing ubuntu/debian server

## When to choose
- you administer a Linux server and want step-by-step hardening instructions with explanations
- you want a curated, actively updated reference covering SSH, firewall, and intrusion detection setup

## When to avoid
- you need automated tooling rather than a manual guide
- you need security guidance for Windows or macOS servers
- you need compliance-audit-grade documentation

## Facets
- artifact type: learning-resource
- maturity: active
- function: security, documentation
- domain: security, operating-systems, self-hosted, developer-tools
- platform: cli
- tags: server-hardening, security-guide, ssh, firewall, fail2ban, ufw, tutorial, linux
