An Ansible collection providing battle-tested security hardening for Linux, SSH, nginx, and MySQL.
Ansible OS Hardening is an Ansible collection that provides automated security hardening configurations for Linux operating systems, SSH services, nginx web servers, and MySQL databases. It solves the problem of manually implementing and maintaining security best practices across infrastructure by offering battle-tested, compliance-aligned automation. The collection helps organizations reduce their attack surface and maintain consistent security postures.
System administrators, DevOps engineers, and security professionals who manage Linux infrastructure and need to implement security hardening at scale. It's particularly valuable for teams using Ansible for configuration management in production environments.
Developers choose this collection because it provides production-ready, battle-tested security configurations that align with DevSec security baselines. It saves significant time compared to manual hardening while ensuring consistency and compliance across diverse infrastructure components.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Explicitly lists supported OS versions for CentOS, Debian, Ubuntu, and others with detailed compatibility, ensuring hardening works across diverse production environments.
Designed to align with DevSec Inspec baselines for Linux, SSH, nginx, and MySQL, providing a standardized approach for security auditing and compliance checks.
Offers battle-tested Ansible roles that automate security hardening, reducing manual configuration errors and ensuring consistency across infrastructure.
Multiple CI/CD badges in the README show continuous integration workflows, indicating regular testing, maintenance, and reliability for production use.
The README admits that apache_hardening and windows_hardening roles are not functional, limiting its applicability for common web servers and Windows environments.
Requires Ansible >= 2.16, which may force costly upgrades or be incompatible with legacy setups, adding deployment overhead.
For distributions like Amazon Linux and Arch Linux, only 'some roles' are supported, leading to inconsistent hardening and potential security gaps.
Focuses only on OS, SSH, nginx, and MySQL; missing hardening for other critical services like databases or applications, requiring supplementary tools.
