Lynis is a security auditing for UNIX derivatives like Linux, macOS, BSD, and others. It performs an **in-depth security scan** and runs on the system itself. The primary goal is to test security defenses and **provide tips for further system hardening**. It will also scan for general system information, vulnerable software packages, and possible configuration issues. Lynis was commonly used by people in the "blue team" to assess the security defenses of their systems. Nowadays, penetration testers also have Lynis in their toolkit.
We believe software should be **simple**, **updated on a regular basis**, and **open**. You should be able to trust, understand, and have the option to change the software. Many agree with us, as the software is being used by thousands every day to protect their systems.
If you want to run the software as `root`, we suggest changing the ownership of the files. Use `chown -R 0:0` to recursively alter the owner and group and set it to user ID `0` (`root`).
Stable releases of Lynis are packaged and made available as RPM or DEB package. The [CISOfy software repository](https://packages.cisofy.com) can be used to install Lynis on systems running :
