# Audit Linux host hardening drift before exposing SSH or rolling to production
Uses Lynis to run an on-host security audit and turn the findings into a prioritized hardening checklist for an agent or operator. Invoke it when a machine is about to become internet-facing, after base image changes, or whenever you need a quick read on hardening drift instead of a generic vulnerability scan.
## Prerequisites
Shell access to the target UNIX-like host, with root or sudo recommended for fuller audit coverage
## Installation
- Choose whichever fits your setup:
+ Use the upstream install or setup path that matches your environment:
+ - git clone https://github.com/CISOfy/lynis
- 1. Copy this skill folder into your local skills directory.
- 2. Clone the repo and symlink or copy the skill into your agent workspace.
- 3. Add the repo as a git submodule if you manage shared skills centrally.
- 4. Install it through your internal provisioning or packaging workflow.
- 5. Download the folder directly from GitHub and place it in your skills collection.
+ Requirements and caveats from upstream:
+ - Article by TechRepublic, considering Lynis a "must-have" tool: [How to quickly audit a Linux system from the command line](http://www.techrepublic.com/article/how-to-quickly-audit-a-linux-system-from-the-command-line/)
- Install command or upstream instructions:
+ Basic usage or getting-started notes:
+ - There are multiple options available to install Lynis.
+ - ### Software package
+ - For systems running Linux, BSD, and macOS, there is typically a package available. This is the preferred method of obtaining Lynis, as it is quick to install and easy to update. The Lynis project itself also provides...
- ```
- git clone https://github.com/CISOfy/lynis && cd lynis && ./lynis audit system
