 We also wanted to replace Inspec with its free distribution [cinc-auditor](https://cinc.sh/). This was surprisingly easy as the people behind cinc made it very easy to install cinc-auditor and use it as a drop-in replacement for Inspec.

 Our mysql-hardening-role relies on a existing installation of MySQL or MariaDB. For this we used geerlingguys mysql-role because it supports many operating systems.
