## What it is
An Ansible collection of battle-tested hardening roles for Linux operating systems, SSH, nginx, and MySQL/MariaDB. It automates secure configuration and attack-surface reduction, aligned with the DevSec InSpec compliance baselines.

## Use cases
- harden linux servers with ansible
- secure sshd configuration automatically
- apply cis-style hardening to ubuntu and debian servers
- harden nginx and mysql configurations
- automate server security compliance
- reduce attack surface of cloud vms
- enforce secure sysctl kernel settings

## When to choose
- you use Ansible to provision or manage Linux servers and want automated, tested hardening
- you need compliance with DevSec/InSpec baselines or similar security standards
- you want maintained, community-validated secure defaults for SSH, nginx, MySQL, and the OS

## When to avoid
- your infrastructure is not managed with Ansible (consider the Chef or Puppet variants of dev-sec instead)
- you need hardening for Windows servers or other services like Apache or PostgreSQL
- you require fully hands-off compliance certification rather than configuration automation

## Facets
- artifact type: plugin
- maturity: active
- function: security, configuration-management, developer-tools
- domain: security, self-hosted, infrastructure-as-code
- platform: self-hosted, cloud
- tags: ansible, ansible-collection, hardening, ssh-hardening, os-hardening, nginx-hardening, mysql-hardening, sysctl, devsec, compliance, cis-benchmark, devops, linux
