How to scan the complete system for vulnerabilities 🛠️ System Security Audit with Lynis | Linux Tutorial

How to do a complete security audit of a Linux, macOS, BSD, Solaris or Unix system with the Lynis tool, to identify vulnerabilities, security problems, wrong configurations or unprotected services, and to be able to solve the problems to harden and protect the system against cybercriminal attacks over the Internet

The Lynis program will make a detailed scan of the system, and all of its security defenses to detect problems or vulnerabilities that may exist and compromise access to the system and data. The results of the scan will be displayed for various categories and services running, indicating whether everything is fine, installed, poorly configured, vulnerable, and suggestions you can make to solve the problem, configure or activate the service.

It is very important that a network administrator and a system or server, perform a professional audit of the system, to improve the security of the system or server, and ensure that the system is not compromised or vulnerable to attacks, does not have services vulnerable to access unauthorized, and able to block cybercriminal attacks via the internet or the local area network (LAN), in order to prevent the system from failing or being the victim of theft of data and stored information.
