The command "sudo lynis audit system" is a Linux command that initiates a security audit using the Lynis tool.

Here's a breakdown of the command:

• "sudo": It is used to execute the command with administrative privileges. It allows the user to run the command as the root user or another superuser account.
• "lynis": It is the command-line interface (CLI) tool for performing security audits and hardening systems. Lynis is designed to scan the system for vulnerabilities, configuration issues, and any areas where security improvements can be made.
• "audit": It specifies the Lynis audit mode, which instructs Lynis to assess the system's security posture by scanning various components, including file systems, network settings, software packages, and more.
• "system": It indicates that the Lynis audit should be performed on the entire system. This means it will scan the entire operating system, including all installed software, services, and configurations.

By running this command, Lynis will start evaluating your system's security and generate a report highlighting potential vulnerabilities, recommendations, and suggestions for improving the security configuration of your Linux system.
