Lynis, the security auditing tool for Unix based systems.

I uploaded new Lynis-2.1.1-1 to Debian archive. Now it is available in Debian Testing.

This new version includes checks for Docker files, new reviewed tests for Debian systems, between others.

Lynis is an auditing tool for Unix. It scans the system configuration and creates an overview of system information

and security issues usable by professional auditors.

You can download from Debian repository: https://packages.debian.org/stretch/lynis

Or better:

# apt-get install lynis
