Ansible Hardening

Ansible Hardening is an Ansible role that applies security hardening to Linux hosts. It rolls a defined hardening baseline out across every system you manage with Ansible, so the same security settings land consistently on each one.

Because it is plain Ansible, hardening runs as part of your normal provisioning and configuration workflow rather than as a separate manual step. It was originally built for OpenStack-Ansible deployments but applies to general Linux fleets.

It runs entirely within your own Ansible control environment against the hosts you target, with no external service involved. The role is open under the Apache 2.0 license, so the exact changes it makes can be reviewed and tailored before rollout.
