How to Use Lynis in Kali Linux: Basic and Advanced Security Auditing

Lynis is an open-source security auditing tool used to ensure that Linux systems are secure. It identifies security vulnerabilities and provides suggestions for improving system security. In this article, we will discuss how to use Lynis in Kali Linux for basic and advanced security auditing.

Installing Lynis in Kali Linux

To install Lynis in Kali Linux, use the following command in the terminal:

sudo apt install lynis

This command downloads and installs the latest version of Lynis on your Kali Linux system.

Basic Usage of Lynis

To run a basic system audit, use the following command:

perlCopy codesudo lynis audit system

This command provides suggestions for improving system security. The output is organized by severity level, with critical suggestions listed first.

Advanced Usage of Lynis

While the basic audit is a great starting point, Lynis also provides advanced features that allow you to perform more detailed audits and customize the output. Here are a few examples of how to use Lynis for more advanced security auditing:

Customizing the Profile

To use a custom profile, create a new profile file and use the “-c” flag to specify the path to the new profile file. For example:

sudo lynis audit system -c /path/to/custom/profile.prf

This will run the system audit using the custom profile file instead of the default profile.

Running Specific Tests

If you want to run a specific test, use the “–tests” flag followed by the test ID or keyword. For example, to run a test for known vulnerable software packages, use the following command:

sudo lynis audit system --tests vulnerabilities

This will run the audit and provide suggestions for known vulnerable software packages.

Generating a Report

Lynis allows you to generate a report of the audit results in various formats, including HTML, text, and JSON. To generate a report, use the “-Q” flag followed by the desired report format. For example, to generate an HTML report, use the following command:

sudo lynis audit system -Q html --output /path/to/report.html

This will generate an HTML report of the audit results and save it to the specified file path.

Conclusion

Lynis is a powerful tool that can help you identify security vulnerabilities and improve the overall security of your Kali Linux system. By using the basic and advanced features of Lynis, you can customize the auditing process and generate detailed reports to help you make informed decisions about system security. Whether you are a novice or an advanced user, Lynis is a valuable addition to your security toolkit.
