Lynis - Security Tool

Introduction

Lynis is an open-source security tool. It scans the system and all the installed software. It performs many individual security control checks. It determines the hardening state of the machine, detects security issues, and provides suggestions to improve the security defense of the system.

cPanel's Technical Support cannot assist in the installation or usage of Lynis. If you're not comfortable with the command line, you may want a qualified systems administrator to assist with the installation and usage of Lynis.
