If you manage a Linux server or use it as your daily driver, keeping your system safe from hidden threats is a top priority. One of the best ways to do this is by using Lynis.
What is Lynis?
Lynis is a powerful, open-source security auditing tool designed specifically for Unix-like operating systems. Instead of just doing a basic virus scan, it performs a deep health check on your entire system. It evaluates your software, settings, firewall configurations, and password rules to see if they follow current security best practices.
Once the scan is complete, Lynis gives your system a "hardening index" score. Best of all, it doesn't just point out your flaws it gives you direct, easy-to-understand advice on how to fix the specific vulnerabilities it discovers so you can immediately improve your score.
